This datasheet details the National Semiconductor DS75160A, DS75161A, and DS75162A high-speed Schottky 8-channel bi-directional transceivers for IEEE-488…
The document describes a family of high-speed Schottky 8-channel bi-directional transceivers designed to interface TTL/MOS logic with the IEEE Standard 488-1978 General Purpose Interface Bus (GPIB). The family includes three specific devices: DS75160A for data lines, and DS75161A or DS75162A for management lines in single or multi-controller systems respectively. Key features include internal bus termination that disconnects when power is removed to prevent loading, PNP inputs for minimum loading, and hysteresis at receiver inputs.
| Supply Voltage (Vcc) | 4.75 to 5.25 V |
|---|---|
| Operating Temperature Range | 0°C to +70°C |
| Storage Temperature Range | -65°C to +150°C |
| Number of Channels | 8-channel bi-directional |
| Logic Standard | IEEE Standard 488-1978 |
The operating supply voltage (Vcc) ranges from a minimum of 4.75 V to a maximum of 5.25 V.
Yes, the IEEE-488 required bus termination is provided internally with an active turn-off feature.
DS75160A is implemented for the 8 data lines, while DS75161A or DS75162A are used for the 8 management signal lines.
