Overview
The 74LVC574APW/S400,1 is an 8-bit positive-edge triggered D-type flip-flop manufactured by Nexperia USA Inc. It features three-state outputs and operates within a supply voltage range of 1.65V to 3.6V. The device provides high noise immunity and low power consumption, complying with JEDEC standards for various voltage levels. It supports propagation delays of 7ns at 3.3V with 50pF load and offers output currents of 24mA for both high and low states. The component is housed in a 20-TSSOP package and functions reliably across temperatures from -40°C to +125°C.
Feature Summary
- Positive-edge triggered data transfer mechanism
- Three-state output capability for bus driving
- Wide operating voltage range supporting multiple logic families
- High ESD protection tolerance
Applications
- Parallel-to-serial data conversion circuits
- I/O buffering and interface isolation
- Digital signal processing register stages
- Microcontroller peripheral control interfaces
Procurement Notes
Verify the specific suffix S400,1 against official Nexperia documentation to confirm tape and reel specifications and moisture sensitivity level. Ensure compatibility with existing PCB footprints for the 20-TSSOP package. Cross-reference RoHS compliance status with current environmental regulations before finalizing procurement orders.
Selection Notes
Select this component when an 8-bit storage element with tri-state outputs is required for low-voltage digital systems. Consider the 20-TSSOP package for surface-mount applications requiring moderate pin density. Evaluate the 7ns propagation delay against system clock speeds to ensure timing margins are met under maximum load conditions.
Part Context
This part belongs to the 74LVC series, designed for low-voltage CMOS applications. It serves as a fundamental building block for sequential logic circuits. The APW variant indicates a specific plastic wave package configuration. Integration into larger systems typically involves connecting clock and data lines to standard logic interfaces.
Replacement Considerations
The 74LVC574ABQ,115 is a documented substitute offering similar functionality in a different 20-VFQFN package. Verify pinout compatibility and thermal characteristics when substituting between TSSOP and QFN form factors.
