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 in cludes a 180Ωterminating 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)
