Overview
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.
Connecting the RA and/or RB pins to the (−) input yields an input impedance in the range of 3 kΩ to 7 kΩ and satisfies RS-232-C requirements; leaving RA and/or RB pins unconnected, the input resistance will be greater than 6 kΩ to satisfy MIL-STD-188C.
The output circuitry is TTL/DTL compatible and will allow “collector-dotting” to generate the wired-OR function.
A TTL/ DTL strobe is also provided for each receiver.
