INFORMATION

The SN65C1167E and SN65C1168E consist of dual

drivers and dual receivers with

±15-kV ESD (Human

Body Model [HBM]) and

±8-kV ESD (IEC61000-4-2

Air-Gap

Discharge

and

Contact

Discharge)

for

RS-422

bus

pins.

The

devices

meet

the

requirements

of

TIA/EIA-422-B

and

ITU

recommendation V.11.

The SN65C1167E combines dual 3-state differential

line drivers and 3-state differential line receivers,

both of which operate from a single 5-V power

supply. The driver and receiver have active-high and

active-low

enables,

respectively,

which

can

be

connected together externally to function as direction

control.

SN65C1168E drivers have individual active-high

enables.
