SN75C3222E

SN65C3222E, SN75C3222E SLLS725B – JUNE 2006 – REVISED AUGUST 2021 3-V to 5.5-V Multichannel RS-232 Line Drivers and Receivers with ±15-kV ESD Protection 1 Features ESD Protection for RS-232 bus pins – ±15-kV Human-body model (HBM) – ±8-kV IEC 61000-4-2, Contact discharge – ±15-kV IEC 61000-4-2, Air-gap discharge Meet or exceed the requirements of TIA/EIA-232-F and ITU v.28 standards Operate with 3-V to 5.5-V VCC supply Operate up to 1000 kbit/s Two drivers and two receivers Low standby current . . . 1 μA Typ External capacitors . . . 4 × 0.1 μF Accepts 5-V Logic Input with 3.3-V supply 2 Applications Industrial PCs Wired Networking Data center and networking equipment Notebooks Hand-held equipment 3 Description The SN65C3222E and SN75C3222E consist of two line drivers, two line receivers, and a dual chargepump circuit with ±15-kV ESD protection pin to pin (serial-port connection pins, including GND). The devices meet the requirements of TIA/EIA-232F and provide the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply. The devices operate at typical data signaling rates up to 1000 kbit/s and are improved drop-in replacements for industry-popular '3222 twodriver, two-receiver functions. The SN65C3222E and SN75C3222E can be placed in the power-down mode by setting the power-down ( PWRDOWN) input low, whi...
