ST207EB ST207EC ± 15 kV ESD protected 5 V RS-232 transceiver Features ■ ESD protection for RS-232 i/o pins: ±15 kV human body model ■ 230kbps data rate ■ Guaranteed slew rate 3 V/ms (min.) ■ Operates from a single 5 V power supply ■ Packaged in SSO-24 and TSSOP24 Description SSOP TSSOP The ST207E is a 5 driver and 3 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 and receivers of the ST207E meet all EIA/TIA232E and CCITT V.28 specifications at data rates up to 120 Kbps, when loaded in accordance with the EIA/TIA-232E specification. The ST207E operates with four 0.1 µF capacitors. It came in 24-pin SSOP and TSSOP packages. Table 1.
