Latches Procurement Notes

Verify the specific suffix AM96-HC against manufacturer documentation to confirm packaging and temperature grade details. Ensure compatibility with existing board layouts for the PDSO24 footprint. Confirm RoHS status and lead times through authorized distributors, as this component may be subject to availability constraints due to its age or discontinuation status.

Latches Selection Notes

Select this component when an octal latch with fast CMOS performance is required for 5V logic systems. Consider the 6.8 ns propagation delay for timing-critical designs. Verify that the 0°C to +70°C operating range meets environmental requirements. Compare output drive capabilities against load specifications to ensure signal integrity across the bus.

Latches Part Context

This part belongs to the Harris FCT series, designed for high-speed digital applications. It serves as a successor to earlier TTL-compatible logic families, offering improved speed and lower power consumption. The device is part of a broader ecosystem of FCT logic components used in computing and telecommunications equipment.

Latches Replacement Considerations

Check for direct pin-to-pin replacements such as the SN74FCT843 or equivalent parts from other manufacturers like Texas Instruments. Verify electrical characteristics and package dimensions before substitution.
