SN74ABT574ANSRG4

Flip Flops Overview

The SN74ABT574ANSRG4 is an octal edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 6.6 ns at 5 V with 50 pF load. The device provides high drive capability with output currents of -32 mA (high) and 64 mA (low). It is housed in a 20-SOIC package, supports surface mount installation, and functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage
• Three-state outputs allowing direct connection to bus systems without external buffers
• High-speed performance enabled by ABT technology with low propagation delay
• Strong drive capability supporting heavy capacitive loads on the output lines

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register implementations
• Clock domain crossing synchronization stages
• General-purpose digital logic buffering and latching

Flip Flops Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and manufacturing revisions as defined by Texas Instruments. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the operating environment stays within the specified -40°C to +85°C temperature range. Cross-reference the datasheet revision date to ensure compatibility with current design standards.

Flip Flops Selection Notes

Select this component when an octal latch with tri-state control is required for 5V logic systems. It serves as a suitable replacement for older 74FCT or 74ACT series devices where higher speed and drive strength are needed. Consider the 20-pin SOIC package constraints during layout. Verify that the input voltage levels remain compatible with TTL thresholds if interfacing with legacy logic families.

Flip Flops Part Context

This part belongs to the SN74ABT family of BiCMOS logic devices known for high-speed operation and reduced power consumption compared to standard bipolar technologies. The ABT series bridges the gap between fast Schottky TTL and CMOS flexibility. The SN74ABT574 variant specifically focuses on octal storage applications requiring robust output drivers and precise timing characteristics for synchronous digital designs.

Flip Flops Replacement Considerations

SN74ABT574AN: Same logical function but in a PDIP-20 through-hole package. SN74ABT574ADBR: Same function in a smaller SOIC-20 package. SN74ABT574APWR: Equivalent function in a TSSOP-20 package. SN74ABT574ARGYR: Equivalent function in a VQFN-20 package.
