This datasheet describes high-speed Schottky 8-channel bi-directional transceivers for interfacing TTL/MOS logic to the IEEE Standard 488-1978 General…
The DS75160A and DS75161A are high-speed Schottky 8-channel bi-directional transceivers designed to interface TTL/MOS logic to the IEEE Standard 488-1978 General Purpose Interface Bus (GPIB). The family features PNP inputs for drivers to minimize loading, hysteresis at receiver inputs for noise margin, and internal bus termination with an active turn-off feature. The DS75160A is used for the eight data lines, while the DS75161A implements the management signal lines.
| Supply Voltage (V CC) | 4.75 to 5.25 V |
|---|---|
| Ambient Temperature Range (TA) | 0 to 70 °C |
| Maximum Power Dissipation | 1897 mW (at 25°C) |
| Output High Voltage (VOH) | 2.7 to 3.5 V |
| Output Low Voltage (VOL) | 0.3 to 0.5 V |
They meet the IEEE Standard 488-1978.
Yes, they include on-chip bus terminators that disconnect when V CC is removed.
PNP inputs are used at all driver inputs to minimize loading.
