What are the key features of TRS202EINE4?
- Dual RS-232 line driver and receiver in a single 16-pin DIP package, providing 2 drivers and 2 receivers for full-duplex serial communication
- Schmitt trigger inputs with EIA-232/TIA-232/V.28 compliance ensuring noise-immune reception of RS-232 signals up to ±15V
- 5V single-supply operation with integrated charge pump capacitors, eliminating the need for separate ±12V power rails in RS-232 interface designs
What is TRS202EINE4 used for?
TRS202EINE4 is used in embedded systems, industrial controllers, and legacy serial interfaces requiring RS-232 communication between microcontrollers and external devices such as modems, GPS modules, barcode scanners, and PLCs. It is especially practical in 5V microcontroller designs where a single-supply dual driver/receiver simplifies the interface to RS-232 DB9 connectors without a bipolar power supply.

Frequently Asked Questions
How many RS-232 driver and receiver channels does TRS202EINE4 provide and what supply voltage does it require?
TRS202EINE4 integrates 2 RS-232 line drivers and 2 RS-232 line receivers in a single 16-pin DIP package, operating from a 5V supply. The integrated charge pump generates the ±12V EIA-232 swing from the 5V rail internally, so no external bipolar power supply is needed, simplifying RS-232 interface design in single-supply microcontroller systems.
What noise immunity benefit do the Schmitt trigger inputs of TRS202EINE4 provide in industrial serial communication applications?
The Schmitt trigger inputs of TRS202EINE4 provide hysteresis on the RS-232 receive path, allowing reliable logic-level detection even when the incoming signal has slow edges or superimposed noise from long cable runs typical of factory floors. The max high-level input current of 0.2mA and EIA-232 compliance allow the device to tolerate up to ±15V signal swings from the RS-232 line, making it robust in electrically noisy industrial environments.
For a legacy serial retrofit project, when would TRS202EINE4 in a 16-pin DIP be preferred over a smaller SOIC version?
TRS202EINE4 in 16-pin DIP through-hole format is preferred in legacy retrofit projects where existing PCBs have through-hole RS-232 IC footprints, hand assembly is required, or direct DIP socket replacement of older line transceivers such as MAX232 is needed. The 0.3-inch DIP-16 footprint is pin-compatible with industry-standard RS-232 transceivers, reducing redesign effort when upgrading aging industrial or laboratory serial interfaces.
