Flip Flops datasheet and documents for SN74AHCT574DW

SN74AHCT574DW

Flip Flops Overview

The SN74AHCT574DW is an octal edge-triggered D-type flip-flop with three-state outputs from the Texas Instruments AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The device provides a maximum propagation delay of 10.6 ns at 5 V with 50 pF load, supporting clock frequencies up to 115 MHz. It utilizes a 20-SOIC surface-mount package and functions reliably across an industrial temperature range of -40°C to +125°C.

Flip Flops Feature Summary

Octal configuration providing eight independent D-type flip-flops in a single integrated circuit
Three-state outputs allowing direct bus-driven connections without external buffers
TTL-compatible input thresholds enabling seamless interfacing with legacy logic systems

Flip Flops Applications

Parallel-to-serial data conversion circuits
Register file implementations in microprocessor systems
High-speed buffering for digital signal processing interfaces

Flip Flops Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 package variant rather than tape-and-reel configurations like 'DWR'. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management aligns with the specified operating temperature limits during system design.

Flip Flops Selection Notes

Select this component when TTL-level input compatibility is required alongside high-speed performance. The AHCT series bridges CMOS speed with TTL voltage levels. Consider the SOIC-20 footprint constraints and verify that the 8 mA output drive capability meets the load requirements of the destination circuitry.

Flip Flops Part Context

This part belongs to the SN74AHCT574 family of octal D-type flip-flops. It shares functional architecture with variants such as SN74AHCT574N and SN74AHCT574DR but differs in physical packaging. The DW designation specifically identifies the plastic small-outline package format used for surface-mount assembly processes.
