Latches Procurement Notes

Verify the complete part number including suffixes such as 'AMTCX' against manufacturer datasheets to ensure correct package type and tape-and-reel specifications. Confirm voltage ratings and temperature ranges match your specific application requirements before ordering. Cross-reference with current Fairchild or ON Semiconductor documentation to validate availability and any potential obsolescence notices.

Latches Selection Notes

Select this component when designing systems requiring octal latching with TTL-compatible inputs at low voltages. Ensure the operating voltage aligns with the 2.0V to 3.6V specification. Consider the TSSOP package size for space-constrained designs. Verify that the required propagation delay and output drive strength meet system timing constraints compared to alternative logic families.

Latches Part Context

This component belongs to the 74VHCT series of high-speed CMOS logic devices. It serves as a critical interface element between microprocessors and peripheral devices. The VHCT technology bridges the gap between older TTL standards and modern low-voltage CMOS implementations. This specific model provides reliable data retention and transfer capabilities essential for synchronous digital design architectures.

Latches Replacement Considerations

Check for equivalents from ON Semiconductor, which acquired Fairchild's logic division. Verify pin compatibility and electrical parameters against datasheets for potential substitutes like the 74VHCT573ATC or similar octal latches. Ensure voltage levels and package dimensions are identical to avoid redesign efforts.
