DS9627 - Dual Line Receiver

General Description

The DS9627 is a dual-line receiver which meets the electrical interface specifications of EIA RS-232C and MIL-STD-188C.

The input circuitry accommodates ± 25V input signals and the differential inputs allow user selection of either inverting or non-inverting logic for the receiver operation.

DS9627 Dual Line Receiver February 1996 DS9627 Dual Line Receiver General Description The DS9627 is a dual-line receiver which meets the electrical interface specifications of EIA RS-232C and MIL-STD-188C. The input circuitry accommodates ± 25V input signals and the differential inputs allow user selection of either inverting or non-inverting logic for the receiver operation. The DS9627 provides both a selectable hysteresis range and selectable receiver input resistance. When pin 1 is tied to V−, the typical switching points are at 2.6V and −2.6V, thus meeting RS-232-C requirements. When pin 1 is open, the typical switching points are at 50 µA and −50 µA, thus satisfying the requirements of MIL-STD-188C LOW level interface.
