Latches Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance and lead-free status. Ensure the ordering code matches the specific DGGR package variant. Confirm that the intended application environment falls within the specified -40°C to +85°C operating temperature range. Validate power supply requirements against the 2V to 5.5V operational limits before procurement.

Latches Selection Notes

Select this component when designing systems requiring 16-bit parallel latching with three-state control. The AHCT series is appropriate for designs needing interface compatibility between CMOS logic and TTL-level signals. Consider the 48-TSSOP package dimensions for PCB layout constraints. Evaluate the 1ns propagation delay against system timing requirements to ensure signal integrity at target clock speeds.

Latches Part Context

This device belongs to the SN54/74AHCT16373 family of 16-bit transparent latches. It shares functional similarities with other members like the SN74AHC16373 but differs in input threshold characteristics to support TTL compatibility.
