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