Flip Flops datasheet and documents for SN74HC574PWT
Flip Flops Overview
The SN74HC574PWT is an octal edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It belongs to the HC logic series and operates within a supply voltage range of 2 V to 6 V. The device features non-inverting inputs and outputs, with a typical propagation delay of 265 ns at 5 V. Output drive capabilities include -7.8 mA for high level and 7.8 mA for low level. It is housed in a 20-TSSOP package (0.173" width) and supports surface-mount installation. The operating temperature range spans from -40 °C to +85 °C.
Flip Flops Feature Summary
- Octal configuration providing eight independent D-type flip-flops sharing a common clock and output enable.

Flip Flops Procurement Notes
Verify the specific suffix 'PWT' against official Texas Instruments documentation to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with standard 20-TSSOP footprints during PCB layout. Confirm RoHS compliance status through current manufacturer declarations prior to procurement.
Flip Flops Selection Notes
Select this component for designs requiring octal data storage with tri-state bus interfacing capabilities. The HC series offers CMOS compatibility with TTL input levels. Consider the 265 ns propagation delay for timing constraints. Verify that the 2 V to 6 V supply range aligns with system power requirements.
Flip Flops Part Context
This part is part of the SN74HC574 family of octal edge-triggered D-type flip-flops. It shares functional similarities with variants like SN74HC574PWR and SN74HC574AN but differs in packaging and specific electrical characteristics defined by the manufacturer's datasheet for the PWT suffix.
Flip Flops Replacement Considerations
SN74HC574PWR is a documented alternative with identical logical function in a TSSOP-20 package. Verify pinout compatibility and electrical parameters before substitution.
