SN74ALS534ADWR

Flip Flops Overview

The SN74ALS534ADWR is an octal D-type edge-triggered flip-flop from the Texas Instruments ALS logic series. It features eight independent D-type flip-flops with positive-edge triggering and three-state outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 16 ns, a high-level output current of -2.6 mA, and a low-level output current of 24 mA. It is housed in a 20-SOIC package and supports TTL input levels.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage
• Positive-edge triggering mechanism synchronized with clock signal transitions
• Three-state output capability allowing direct bus line connections without external buffers
• Inverting polarity design compatible with standard TTL input logic levels

Flip Flops Applications

• Parallel data storage registers in digital systems
• Shift register configurations for serial-to-parallel conversion
• Buffering interfaces between microprocessors and peripheral devices
• State holding elements in sequential logic circuits

Flip Flops Procurement Notes

Verify that the ordering suffix ADWR corresponds to the SOIC-20 surface mount package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply voltage constraints remain strictly within the 4.5 V to 5.5 V operational window to maintain specified timing characteristics and prevent device malfunction during operation.

Flip Flops Selection Notes

Select this component when an octal storage solution with three-state outputs is required for bus-oriented architectures. The ALS series offers faster switching speeds compared to standard LS logic while maintaining lower power consumption than AS variants. Consider the 16 ns propagation delay and specific drive currents when designing for high-speed data transfer requirements or heavy capacitive loads on the output lines.

Flip Flops Part Context

This part belongs to the SN74ALS5xx family of octal logic devices manufactured by Texas Instruments. It shares the 20-SOIC footprint and 5V operating environment with related components like the SN74ALS537 and SN74ALS574. The ALS technology provides a performance balance suitable for general-purpose digital applications requiring moderate speed and reliable data retention capabilities.
