SN74ALS760DWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS760DWRE4 is an octal buffer and line driver from the Texas Instruments ALS logic family. It features eight non-inverting inputs driving open-collector outputs, designed to improve performance in 3-state memory address drivers and bus-oriented receivers. The device operates on a supply voltage (VCC) ranging from 4.5 V to 5.5 V. It provides a low-level output current (IOL) of up to 24 mA at VCC = 4.5 V. Propagation delays are specified between 5 ns and 16 ns depending on the input-to-output path and load conditions (CL = 50 pF). The component is housed in a 20-pin Small-Outline (DW) package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix matches the required tape-and-reel packaging configuration. Confirm the RoHS compliance status and lead finish details against the latest Package Option Addendum. Ensure the selected variant aligns with the intended operating temperature range and moisture sensitivity level requirements for the assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with open-collector outputs to simplify bus arbitration. The ALS technology offers a balance of speed and power consumption compared to standard TTL. Consider the 24 mA sink capability for direct bus interfacing without additional pull-up resistors if the system design accommodates the open-collector topology.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74ALS760 series, which includes variants such as the SN74ALS760DWG4 and SN74ALS760N. It serves as an open-collector alternative to the 3-state SN74ALS244. The DW package designation indicates a plastic small-outline integrated circuit format, distinct from the through-hole PDIP options available in the same logical family.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the open-collector output structure benefit bus applications?

The open-collector outputs allow multiple devices to share a common bus line without electrical conflict, effectively eliminating the need for separate 3-state overlap protection logic.

What is the maximum low-level output current capability?

The device can sink up to 24 mA of low-level output current when the supply voltage is 4.5 V.
