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 01
F 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.

ABSOLUTE MAXIMUM RATINGS
Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is
not implied. V+ and V- can have a maximum magnitude of +7V, but their absolute addition can not exceed 13 V.
