SN74ACT574PW

Flip Flops Overview

The SN74ACT574PW is an octal D-type flip-flop from the Texas Instruments ACT logic family, housed in a 20-pin TSSOP surface-mount package. It features non-inverting outputs with three-state capability and TTL-compatible inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V, supporting a propagation delay of 11 ns. Output drive capabilities include -24 mA at high levels and 24 mA at low levels, ensuring robust signal integrity for digital data storage applications.

Flip Flops Feature Summary

• Octal configuration providing eight independent edge-triggered D-type flip-flops in a single integrated circuit
• Three-state output architecture enabling direct bus connections and efficient system interconnect management
• TTL-compatible input structure allowing seamless integration with legacy logic families without additional level shifting

Flip Flops Applications

• Parallel-to-serial data conversion circuits requiring precise timing control
• Register files within microprocessor-based systems for temporary data holding
• High-speed buffering stages in digital communication interfaces

Flip Flops Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-20 surface-mount package variant rather than through-hole alternatives. Confirm RoHS compliance status and check for automotive or industrial temperature grade requirements against standard commercial specifications before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when a 5V logic interface requires high-speed octal latching with bus isolation. Compare propagation delays against LVTH or ABT series variants if lower voltage operation or faster switching speeds are critical for the target application design constraints.

Flip Flops Part Context

This part belongs to the broader SN74ACT574 series of octal flip-flops. Related packages include the through-hole SN74ACT574N and the tape-and-reel SN74ACT574PWR. All variants share identical electrical characteristics but differ in physical mounting style and factory packaging format.

Flip Flops Replacement Considerations

SN74ACT574N (PDIP-20) and SN74ACT574PWR (TSSOP-20 Reel) offer equivalent electrical performance with different mechanical footprints or packaging formats.
