Flip Flops datasheet and documents for SN74ALS574BDW

SN74ALS574BDW

Flip Flops Overview

The SN74ALS574BDW is an octal D-type edge-triggered flip-flop with three-state outputs manufactured by Texas Instruments. It belongs to the ALS logic series and features a non-inverting polarity. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 14 ns. It provides a low-level output current of 24 mA and a high-level output current of -2.6 mA. Designed for surface-mount applications, it is housed in a SOIC-20 package and functions within a temperature range of 0°C to +70°C.

Flip Flops Feature Summary

Octal configuration containing eight independent D-type edge-triggered flip-flops
Three-state outputs enabling direct bus line connections without additional interface hardware
Advanced Schottky (ALS) logic series providing reduced power dissipation compared to standard TTL

Flip Flops Applications

Parallel data storage and buffering in digital systems
Bus-oriented memory register implementations
I/O port buffering for microprocessor-based designs

Flip Flops Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors due to end-of-life status. Confirm RoHS compliance details as specified in the datasheet. Ensure the SOIC-20 package variant matches the required PCB footprint. Validate that the specific ordering suffix corresponds to the tube packaging format rather than tape-and-reel alternatives.

Flip Flops Selection Notes

Select this component when designing systems requiring octal storage with tri-state capability. The ALS series offers a balance of speed and power consumption suitable for general-purpose logic applications. Ensure the input voltage levels are compatible with TTL standards. Verify that the thermal operating range meets the environmental requirements of the target application.

Flip Flops Part Context

This part is a member of the SN74ALS574B family, representing the wide-body version of the SN74LS574. It serves as a standard octal flip-flop solution within the Texas Instruments logic portfolio. The device is designed for compatibility with existing 54/74 logic circuits while offering improved performance characteristics typical of the Advanced Low-power Schottky technology.
