SN74ACT534PWR

Flip Flops Overview

The SN74ACT534PWR is an octal edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It belongs to the ACT logic series and operates within a supply voltage range of 4.5 V to 5.5 V. The device features a propagation delay of 11.5 ns, with output drive capabilities of -24 mA for high-level and 24 mA for low-level currents. It utilizes TTL input levels and CMOS output levels, housed in a TSSOP-20 surface-mount package. The component supports through-hole or SMD/SMT installation styles depending on specific variant configurations, though this model specifies SMD/SMT mounting. It functions as an inverting logic element suitable for standard digital applications.

Flip Flops Procurement Notes

Verify that the ordering suffix matches the required package type and temperature rating. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure the supplier provides valid traceability records for automotive or industrial grade variants if applicable. Cross-reference the datasheet revision date to guarantee compatibility with existing design specifications and pinout requirements.

Flip Flops Selection Notes

Select this component when an octal register with tri-state outputs is required for system integration. The ACT series offers superior switching speeds compared to legacy 74LS equivalents while maintaining backward compatibility with TTL inputs. Consider the TSSOP-20 package for space-constrained printed circuit board layouts. Evaluate the 11.5 ns propagation delay against system clock frequencies to ensure adequate timing margins for signal integrity.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74ACT family of logic integrated circuits. The ACT series represents a transition technology between older bipolar logic families and modern low-voltage CMOS technologies. It provides enhanced performance characteristics including faster propagation delays and higher noise immunity. The SN74ACT534 specifically addresses applications requiring multiple synchronized data storage elements with flexible output control capabilities.

Flip Flops Replacement Considerations

SN74ACT534N serves as a direct PDIP alternative offering identical electrical characteristics with a different physical footprint. SN74ACT534PW provides a comparable plastic small-outline package option. Verify pin compatibility and thermal performance when substituting across package types. Ensure that any replacement maintains the same 3-state output functionality and ACT series speed grades.
