ST207EH ± 15KV ESD PROTECTED 5V HIGH PERFORMANCE RS-232 TRANSCEIVER ■ ■ ■ ■ ■ ■ ■ SINGLE +5v SUPPLY OPERATION 0.1µF EXTENAL CHARGE PUMP CAPACITORS 500kbps DATE RATE UNDER LOAD LOWER SUPPLY CURRENT 1.5mA (TYP) IDEAL FOR HIGH SPEED RS-232 APPLICATIONS PACKAGED IN SO-24, SSO-24 AND TSSOP24 ESD PROTECTION FOR RS-232 I/O PINS: ±15 KV HUMAN BODY MODEL DESCRIPTION The ST207EH is a high speed enhanced multi-channel RS-232 line transceivers with improved electrical performance. The ST207EH is a superior drop-in replacement to our previous versions as well as popular industry standards. The device feature low-power CMOS construction and the charge pump circuitry that generates the ±10V RS-232 voltag elevels using 01µF charges pump capacitors. The ST207EH include a high transmission rate of 500Kbps, a lower supply current at 1.5mA typical (no load), and a superior ESD performance. The ESD tolerance has been SOP SSOP TSSOP improved for this device over ±15KV for HUMAN Body Model. The ST207EH cames in 24-pin SO, SSO and TSSOP packages.
