SN75146
SN75146 is DUAL DIFFERENTIAL LINE RECEIVER manufactured by Texas Instruments.
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 remendation V.28 with the addition of an external bias resistor. This receiver is designed for low-speed operation below 355 k Hz and has a built-in 5-MHz low-pass filter to attenuate high-frequency noise. The inputs are patible with either a single-ended or a differential line system and the outputs are TTL patible. 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. logic symbol†
