MAX232 pinout: Red: power, Blue: outputs, Green: inputs, Yellow: capacitors

The MAX232 is an integrated circuit first created in 1987 by Maxim Integrated Products that converts signals from a TIA-232 (RS-232) serial port to signals suitable for use in TTL-compatible digital logic circuits. The MAX232 is a dual transmitter / dual receiver that typically is used to convert the RX, TX, CTS, RTS signals.

The drivers provide TIA-232 voltage level outputs (about ±7.5 volts) from a single 5-volt supply by on-chip charge pumps and external capacitors. This makes it useful for implementing TIA-232 in devices that otherwise do not need any other voltages.

The receivers reduce TIA-232 inputs, which may be as high as ±25 volts, to standard 5 volt TTL levels. These receivers have a typical threshold of 1.3 volts and a typical hysteresis of 0.5 volts.

The MAX232 replaced an older pair of chips MC1488 and MC1489 that performed similar RS-232 translation. The MC1488 quad transmitter chip required 12 volt and -12 volt power,^[1] and MC1489 quad receiver chip required 5 volt power.^[2] The main disadvantages of this older solution was the +/- 12 volt power requirement, only supported 5 volt digital logic, and two chips instead of one.

Versions[edit]

The later MAX232A is backward compatible with the original MAX232 but may operate at higher baud rates and can use smaller external capacitors – 0.1 μF in place of the 1.0 μF capacitors used with the original device.^[3] The newer MAX3232 and MAX3232E are also backwards compatible, but operates at a broader voltage range, from 3 to 5.5 V.^[4]^[5]

Pin-to-pin compatible versions from other manufacturers are ICL232, SP232, ST232, ADM232 and HIN232. Texas Instruments makes compatible chips, using MAX232 as the part number.

Voltage levels[edit]

The MAX232 translates a TTL logic 0 input to between +3 and +15 V, and changes TTL logic 1 input to between −3 and −15 V, and vice versa for converting from TIA-232 to TTL. (Note that TIA-232 uses opposite voltages for data and control lines, see RS-232 voltage levels.)

TIA-232 line type and logic level	TIA-232 voltage	TTL voltage to/from MAX232
Data transmission (Rx/Tx) logic 0	+3 V to +15 V	0 V
Data transmission (Rx/Tx) logic 1	−3 V to −15 V	5 V
Control signals (RTS/CTS/DTR/DSR) logic 0	−3 V to −15 V	5 V
Control signals (RTS/CTS/DTR/DSR) logic 1	+3 V to +15 V	0 V

Applications[edit]

TIA-232 to TTL converters that use MAX232

The MAX232(A) has two receivers that convert from RS-232 to TTL voltage levels, and two drivers that convert from TTL logic to RS-232 voltage levels. As a result, only two out of all RS-232 signals can be converted in each direction. Typically, the first driver/receiver pair of the MAX232 is used for TX and RX signals, and the second one for CTS and RTS signals.

There are not enough drivers/receivers in the MAX232 to also connect the DTR, DSR, and DCD signals. Usually, these signals can be omitted when, for example, communicating with a PC's serial interface, or when special cables render them unnecessary. If the DTE requires these signals, a second MAX232 or some other IC from the MAX232 family can be used.

Derivatives[edit]

The MAX232 family was subsequently extended by Maxim to versions with four transmitters (the MAX234) and a version with four receivers and four transmitters (the MAX248), as well as several other combinations of receivers and transmitters. A notable addition is the MAX316x which is able to be electrically reconfigured between differential 5 V (RS-422 and RS-485) and single-ended RS-232 albeit at reduced voltage.

Designers of automotive chargers now have the industry’s smallest and lowest-cost solution with the MAX25430 100W USB Power Delivery (PD) buck-boost controller and protector from Maxim Integrated Products, Inc. As the industry’s most integrated solution, the MAX25430 can reduce design size up to 40 percent compared to competitive solutions and offer the industry’s lowest cost for increasing the number of USB PD ports in vehicles.

Automotive multimedia hubs, including rear-seat entertainment modules and head units, are all expanding in capability as more USB PD chargers are integrated into passenger vehicle cabins. However, there are size, cost, and power constraints – and the MAX25430 addresses all of these.

The MAX25430 integrates a USB Type C Port Controller (TCPC) power regulator, V_CONN cable power supply, buck-boost, and protection, thereby eliminating heat-sink requirements and metal box enclosures to further slash design size by 40 percent compared to competitive multi-IC solutions. In addition, bill-of-materials (BOM) costs are also reduced by 25 percent compared to competitive solutions. The MAX25430 runs 20-degrees (Celsius) cooler at full power compared to competitive automotive USB PD solutions. It needs only one microcontroller (MCU) regardless of the number of ports, while competitors require additional MCUs per port.

For a complete solution, Maxim Integrated also offers the MAX25410 automotive USB PD port protector and the MAX25431 automotive 40V H-bridge buck-boost controller, meeting a wide array of USB charger design needs.

Key Advantages

Smallest Size: Integrates TCPC power regulator, V_CONNpower cable supply, buck-boost, and protection to reduce solution size up to 40 percent
Lowest Cost: Eliminates heat sinks, enclosure boxes, and multiple MCUs to yield 25 percent cost savings
Power Performance: Robust performance in harsh automotive environments while running 20 degrees cooler than the closest competitor
