Key Features
- 8-channel IEEE-488 (GPIB) compliant octal transceiver with Schmitt trigger inputs for noise-immune line reception on instrument bus systems
- 3-state output control on all 8 channels enables bus sharing among multiple talkers and listeners in GPIB measurement setups
- 24-pin SOIC package with standard TTL compatibility simplifies direct interfacing with legacy GPIB instruments and test equipment controllers
Applications
The SN75162BDWG4 is designed for IEEE-488 (GPIB) bus interface circuits in laboratory instruments, automated test equipment (ATE) controllers, and measurement systems requiring 8-bit parallel data transfer. Its Schmitt trigger inputs provide noise immunity on long GPIB cable runs, while 3-state outputs allow multiple devices to share the 8-line bus without bus contention. The 24-pin SOIC package suits both new instrument designs and board-level replacements in legacy ATE systems.

Frequently Asked Questions
What bus standard does the SN75162BDWG4 support, and how many signal lines does it handle simultaneously?
The SN75162BDWG4 implements the IEEE-488 (GPIB) standard and drives or receives 8 bidirectional data lines simultaneously using its octal transceiver architecture. Each channel has a 3-state output, allowing the device to release all 8 lines to high impedance when not acting as talker, which is mandatory for multi-device IEEE-488 bus configurations.
How do the Schmitt trigger inputs of the SN75162BDWG4 improve reliability on long GPIB cable runs?
GPIB cables can extend up to 20 meters and accumulate capacitive loading that degrades signal edges. The Schmitt trigger inputs on the SN75162BDWG4 provide hysteresis of approximately 0.4 V to 0.8 V, converting slow-rising or noisy edges into clean digital transitions at TTL thresholds and preventing multiple triggering that would corrupt 8-bit parallel data transfers.
For a benchtop ATE system, why choose the SN75162BDWG4 over separate TTL buffer and line-driver ICs for the IEEE-488 data bus?
Implementing 8 bidirectional IEEE-488 lines with discrete TTL buffers and 3-state drivers requires at least 2 to 3 separate ICs and careful enable logic to avoid bus contention. The SN75162BDWG4 consolidates all 8 channels plus directional control and Schmitt trigger receivers in a single 24-pin SOIC, reducing PCB area by approximately 60% and eliminating inter-IC timing mismatches that can cause setup violations on the 8-bit GPIB data byte.
