DS26C32AT/DS26C32AM Quad Differential Line Receiver

Check for Samples: DS26C32AM, DS26C32AT

FEATURES

DESCRIPTION

The DS26C32A is a quad differential line receiver

• CMOS Design for Low Power

designed to meet the RS-422, RS-423, and Federal

• ±0.2V Sensitivity over Input Common Mode

Standards 1020 and 1030 for balanced and

Voltage Range

unbalanced digital data transmission, while retaining

• Typical Propagation Delays: 19 ns

the low power characteristics of CMOS.

• Typical Input hysteresis: 60 mV

The DS26C32A has an input sensitivity of 200 mV

over the common mode input voltage range of ±7V.

• Inputs Won't Load Line When V

= 0V

The DS26C32A features internal pull-up and pull-

• Meets the Requirements of EIA Standard RS-

down resistors which prevent output oscillation on

422

unused channels.

• TRI-STATE Outputs for Connection to System

The DS26C32A provides an enable and disable

Buses

function common to all four receivers. It also features

• Available in Surface Mount

TRI-STATE outputs with 6 mA source and sink

• Mil-Std-883C Compliant

capability. This product is pin compatible with the

DS26LS32A and the AM26LS32.
