Drivers

RS-2323T5RSplit logic supply1 MbpsAuto-powerdownVQFN-32

TRS3253EIRSMR is a compact 3-driver, 5-receiver RS-232 transceiver for systems that need 1.65 V to VCC logic-side compatibility and a 3 V to 5.5 V charge-pump supply.

Best for

  • Mixed-voltage UART or logic interfaces requiring RS-232 signaling
  • Portable or battery-powered equipment using auto-powerdown
  • RS-232 connector interfaces needing enhanced ESD protection

Avoid if

  • An isolated RS-232 interface is required
  • The system cannot support the required external charge-pump capacitors
  • More than three RS-232 transmit drivers are needed

Check before use

  • Set VL to the actual logic-domain voltage within 1.65 V to VCC
  • Use capacitor values specified for the chosen VCC voltage
  • Confirm package assembly, thermal-pad, and MSL handling requirements
  • Revalidate lifecycle and current supply status

Questions & answers

TRS3253EIRSMR is a Texas Instruments RS-232 interface IC with three RS-232 drivers and five RS-232 receivers. It uses a split logic supply pin, VL, so the logic-side interface can operate from 1.65 V up to VCC.
