• Three-state balanced CMOS outputs
• Flow-through pinout design

Applications

• Parallel data storage
• Digital bus buffer

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to confirm the exact package type and tape-and-reel specifications. Ensure the component meets the required environmental and electrical standards for the intended application before finalizing procurement.

Selection Notes

Select this component when designing systems requiring octal latching with high noise immunity. The flow-through pinout facilitates efficient PCB routing for bus architectures. Verify that the operating voltage and load capacitance requirements align with the device's recommended operating conditions.

Part Context

This part belongs to the SN74HCS573 family of octal transparent D-type latches. It is designed for applications needing robust signal integrity in noisy environments due to its Schmitt-trigger inputs. The device integrates eight independent latches sharing common control signals.

Replacement Considerations

Consult the manufacturer's cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains compatibility with the 20-pin VSSOP footprint and matches the specified electrical parameters.
