ST207EA-ST207EB-ST207EC
15KV ESD PROTECTED 5V RS-232 TRANSCEIVER
1/13January 2005 ESD PROTECTION FOR RS-232 I/O PINS:
±15 KV HUMAN BODY MODEL 230kbps DATE RATE GUARANTEED SLEW RATE 3V/µs (Min) OPERATES FROM A SINGLE 5V POWER
SUPPLY PACKAGED IN SO-24, SSO-24 AND
TSSOP24
DESCRIPTIONThe 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 ±15KV
electrostatic discharge (ESD) shocks. The drivers
and receivers of the ST207E meet all EIA/
TIA-232E and CCITT V.28 specifications at data
rates up to 120Kbps, when loaded in accordance
with the EIA/TIA-232E specification.
The ST207E operates with four 0.1µF capacitors.
It came in 24-pin SO and TSSOP packages.

Table 3: 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.
