| 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 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 F capacitors. It came in 24-pin SSOP and TSSOP packages. SSOP TSSOP Table 1.
