not implied. V+ and V- can have a maximum magnitude of +7V, but their absolute addition can not exceed 13 V.


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 01mF 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 improved for this device over ±15KV for HUMAN Body Model. The ST207EH cames in 24-pin SO, SSO and TSSOP packages.
