SN74ALS74ADB

Flip Flops Overview

The SN74ALS74ADB is a dual positive-edge-triggered D-type flip-flop from Texas Instruments' ALS logic series. It features TTL-compatible inputs and outputs, housed in a 14-pin SSOP package for surface-mount installation. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to +70°C. Key electrical specifications include a propagation delay of 4.5 ns, a low-level output current of 8 mA, and a high-level output current of -400 µA.

Flip Flops Feature Summary

• Dual positive-edge-triggered D-type flip-flops with dedicated clear and preset functions
• TTL-compatible input and output structures ensuring direct interface compatibility
• Advanced Low-power Schottky (ALS) technology providing high speed with reduced power consumption

Flip Flops Applications

• High-speed digital data storage and register applications
• Parallel-to-serial and serial-to-parallel data conversion circuits
• Timing control and synchronization logic in digital systems

Flip Flops Procurement Notes

Verify the specific suffix 'ADB' confirms the SSOP surface-mount package variant rather than the standard DIP version. Confirm RoHS compliance status through official manufacturer documentation or component markings. Ensure design compatibility with the specified 4.5V to 5.5V operating voltage range and industrial temperature limits before integration.

Flip Flops Selection Notes

Select this component when surface-mount space constraints require an SSOP footprint instead of through-hole packaging. Choose this ALS-series device for applications demanding faster switching speeds compared to standard LS logic while maintaining lower power dissipation. Verify that the required dual flip-flop configuration with independent clear and preset controls matches the system architecture needs.

Flip Flops Part Context

This part belongs to the SN74ALS74A family of dual D-type flip-flops. The 'SN74' prefix indicates standard logic functionality, 'ALS' denotes Advanced Low-power Schottky technology, and '74' identifies the dual flip-flop function. The 'A' suffix typically signifies enhanced specifications or revisions within the series, while 'DB' specifies the SSOP package type.

Flip Flops Replacement Considerations

SN74ALS74AN (DIP package), SN74ALS74AD (SOIC package). These parts share identical logical functionality but differ in physical package dimensions and mounting style.
