SN75C3221 - 3-V to 5.5-V Single-Channel RS-232 Compatible Line Driver/Receiver
Description
The SN65C3221 and SN75C3221 consist of one line driver, one line receiver, and a dual chargepump circuit with ±15-kV ESD protection pin to pin (serial-port connection pins, including GND).
Features
Operate with 3-V to 5.5-V VCC supply.
Operate up to 1 Mbit/s.
Low standby current : 1 μA typical.
External capacitors : 4 x 0.1 μF.
Accepts 5-V logic input with 3.3-V supply.
RS-232 bus-pin ESD protection exceeds ±15 kV
using human-body model (HBM).
Auto-powerdown feature automatically disables
drivers for power savings
