General Description

The DS78C20 and DS88C20 are high performance, dual differential, CMOS compatible line receivers for both balanced and unbalanced digital data transmission. The inputs are compatible with EIA and Federal Standards.

Input specifications meet or exceed those of the popular DS7820/DS8820 line receiver, and the pinout is identical.

A response pin is provided for controlling sensitivity to input noise spikes with an external capacitor. Each receiver includes a 180 Ohm terminating resistor, which may be used optionally on twisted pair lines. The DS78C20 is specified over a -55°C to +125°C operating temperature range, and the DS88C20 over a 0°C to +70°C range.

Features

  • Meets requirements of EIA Standards RS-232-C RS-422 and RS-423, and Federal Standards 1020 and 1030
  • Input voltage range of ±15V (differential or common-mode)
  • Separate strobe input for each receiver
  • ½ VCC strobe threshold for CMOS compatibility
  • 5k typical input impedance
  • 50 mV input hysteresis
  • 200 mV input threshold
  • Operation voltage range = 4.5V to 15V
  • DS7830/DS8830 recommended driver
