MAX232x Dual EIA-232 Drivers/Receivers
1 Features
3 Description
•
The MAX232 device is a dual driver/receiver that
includes a capacitive voltage generator to supply
TIA/EIA-232-F voltage levels from a single 5-V
supply. Each receiver converts TIA/EIA-232-F inputs
to 5-V TTL/CMOS levels. These receivers have a
typical threshold of 1.3 V, a typical hysteresis of 0.5
V, and can accept ±30-V inputs. Each driver converts
TTL/CMOS input levels into TIA/EIA-232-F levels.

9 Detailed Description
9.1 Overview
The MAX232 device is a dual driver/receiver that includes a capacitive voltage generator using four capacitors to
supply TIA/EIA-232-F voltage levels from a single 5-V supply. Each receiver converts TIA/EIA-232-F inputs to 5V TTL/CMOS levels. These receivers have a typical threshold of 1.3 V, a typical hysteresis of 0.5 V, and can
accept ±30-V inputs. Each driver converts TTL/CMOS input levels into TIA/EIA-232-F levels. The driver, receiver,
and voltage-generator functions are available as cells in the Texas Instruments LinASIC™ library. Outputs are
protected against shorts to ground.

9.3 Feature Description
9.3.1 Power
The power block increases and inverts the 5V supply for the RS232 driver using a charge pump that requires
four 1-µF external capacitors.
9.3.2 RS232 Driver
Two drivers interface standard logic level to RS232 levels. Internal pull up resistors on TIN inputs ensures a high
input when the line is high impedance.
9.3.3 RS232 Receiver
Two receivers interface RS232 levels to standard logic levels. An open input will result in a high output on ROUT.
9.4 Device Functional Modes
9.4.1 VCC powered by 5V
The device will be in normal operation.
9.4.2 VCC unpowered
When MAX232 is unpowered, it can be safely connected to an active remote RS232 device.

10 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
10.1 Application Information
For proper operation add capacitors as shown in Figure 6. Pins 9 through 12 connect to UART or general
purpose logic lines. EIA-232 lines will connect to a connector or cable.

11 Power Supply Recommendations
The VCC voltage should be connected to the same power source used for logic device connected to TIN pins.
VCC should be between 4.5V and 5.5V.
12 Layout
12.1 Layout Guidelines
Keep the external capacitor traces short. This is more important on C1 and C2 nodes that have the fastest rise
and fall times.
