ST232ECN

ST202EB, ST202EC, ST232EB, ST232EC ±15 kV ESD-protected 5 V RS-232 transceiver Datasheet - production data Description The ST202EB, ST202EC, ST232EB, and ST232EC are two-driver, two-receiver devices designed for RS-232 and V.28 communications in harsh environments. Each transmitter output and receiver input is protected against ± 15 kV electrostatic discharge (ESD) shocks. The drivers meet all EIA/TIA-232E and CCITT V.28 specifications at data rates up to 230 kbps, when loaded in accordance with the EIA/TIA-232E specification. The ST202EB, ST202EC, ST232EB, and ST232EC use a single 5 V supply voltage. Features ESD protection for RS-232 I/O pins: ± 15 kV human body model Guaranteed 230 kbps date rate Guaranteed slew rate range 3 to 30 V/µs Operates from a single 5 V power supply March 2017 The ST232EB and ST232EC operate with four 1 µF capacitors, while the ST202EB and ST202EC operate with four 0.1 µF capacitors, further reducing cost and board space.
