Product Description

The TRS3253E is a three-driver and five-receiver RS-232 interface device, with split supply pins for mixed-signal operations. All RS-232 inputs and outputs are protected to ±8 kV using the IEC 61000-4-2 Air-Gap Discharge method, ±8 kV using the IEC 61000-4-2 Contact Discharge method, and ±15 kV using the Human-Body Model.
The charge pump requires only four small 0.1-µF capacitors for operation from a 3.3-V supply. The TRS3253E is capable of running at data rates up to 1000 kbps, while maintaining RS-232-compliant output levels.
The TRS3253E has a unique VL pin that allows operation in mixed-logic voltage systems. Both driver in (DIN) and receiver out (ROUT) logic levels are pin programmable through the VL pin. This eliminates the need for additional voltage level shifter while interfacing with low-voltage microcontroller or UARTs. The TRS3253E is available in a space-saving QFN package (4 mm × 4 mm RSM).
Auto-powerdown plus can be disabled when FORCEON and FORCEOFF are high. With auto-powerdown plus enabled, the device activates automatically when a valid signal is applied to any receiver or driver input. INVALID is high (valid data) if any receiver input voltage is greater than 2.7 V or less than –2.7 V, or has been between –0.3 V and 0.3 V for less than 30 µs. INVALID is low (invalid data) if all receiver input voltages are between –0.3 V and 0.3 V for more than 30 µs. Refer to for receiver input levels.
