SN74AS760NS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS760NS is an octal buffer and line driver featuring open-collector outputs, designed to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers. It eliminates the need for 3-state overlap protection through its specific output configuration. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides a low-level output current capability of 64 mA at VCC = 4.5 V. Propagation delays are specified with a maximum of 18.5 ns from input to output and 7 ns from OE to output under standard test conditions (CL = 50 pF). The component is housed in a 20-pin Small-Outline Package (SOP/NS) and supports operation over a temperature range of 0°C to 70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix 'NS' corresponds to the 20-pin SOP package variant rather than the PDIP or SOIC options. Confirm RoHS compliance status as indicated in the manufacturer's packaging addendum. Ensure the procurement specification matches the commercial temperature grade (0°C to 70°C) required for the application environment. Cross-reference the datasheet revision date against the manufacturing lot traceability requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-density bus interfacing is required without complex tri-state logic management. The open-collector design allows for wired-OR configurations and direct drive of higher voltage loads if necessary. Compare propagation delay specifications against system timing budgets. Evaluate the 64 mA sink capability against the total bus capacitance and load requirements to ensure signal integrity is maintained across all channels.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments AS logic family, characterized by advanced Schottky technology for high-speed operation. It serves as an open-collector alternative to standard 3-state buffers like the SN74ALS244. The SN74AS760 complements other octal drivers such as the SN74AS756 and SN74AS757, offering designers flexibility in choosing between inverting/non-inverting outputs and complementary enable signals for complex bus systems.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the open-collector output configuration affect 3-state overlap protection?

The open-collector outputs eliminate the need for external 3-state overlap protection because they cannot source current, preventing contention between multiple drivers on the same bus line.

What is the maximum propagation delay for the SN74AS760NS?

The maximum propagation delay from input to output is 18.5 ns, and from the output enable (OE) to output is 7 ns, measured under standard test conditions with a 50 pF load.
