description

The SN75146 is a dual differential line receiver designed to meet ANSI Standards EIA/TIA-422-B and -423-B.

The receiver is designed to have a constant impedance with input voltages of ±3 V to ±25 V allowing it to meet

the requirements of EIA/TIA-232-E and ITU recommendation V.28 with the addition of an external bias resistor.

This receiver is designed for low-speed operation below 355 kHz and has a built-in 5-MHz low-pass filter to

attenuate high-frequency noise. The inputs are compatible with either a single-ended or a differential line

system and the outputs are TTL compatible. This device operates from a single 5-V power supply and is

supplied in both the 8-pin dual-in-line and small-outline packages.

The SN75146 is characterized for operation from 0°C to 70°C.
