DS88C20 Datasheet | National Semiconductor

Description The DS78C20 and DS88C20 are high performance, dual differential, CMOS patible line receivers for both balanced and unbalanced digital data transmission. The inputs are patible 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 180Ω 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.
