The receiver hysteresis is specified at 300 mV. The 28-TSSOP footprint is a common 4.40 mm body width, compatible with standard SOIC-28 land patterns after adjusting for the finer pitch. ## Supply flexibility — one part for 3.3V and 5V rails The wide supply tolerance also helps with unregulated rails. ## Active lifecycle — no end-of-life pressure for new designs ROHS3 compliance is confirmed, so it passes EU and global material restrictions without an exemption expiry concern.","metaTitle":"TRS3238EIPWR RS-232 Transceiver, 5/3 Drivers, 400 kbps","metaDescription":"TI TRS3238EIPWR full-duplex RS-232 transceiver with 5 drivers and 3 receivers. 400 kbps data rate, 3V to 5.5V supply, -40°C to 85°C.
