SN74LVC1G373DCKR

Latches Overview

The SN74LVC1G373DCKR is a single D-type transparent latch from the Texas Instruments LVC logic family, housed in an SC-70-6 surface-mount package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports I/O port implementation, buffer registers, and bidirectional bus drivers. The device features non-inverting outputs where Q follows D when the latch enable (LE) input is high, latching data when LE is low. Key electrical parameters include a maximum propagation delay of 5.4 ns at 3.3 V and 4 ns at 5 V, with output drive capabilities of ±32 mA. Static current is limited to 10 µA, and it functions reliably across temperatures from -40°C to +125°C.

Latches Feature Summary

• Transparent latch operation allows Q output to follow D input while LE is high, capturing state when LE goes low
• Supports local power-down protection via Ioff feature preventing reverse driving during partial power-off
• Utilizes Texas Instruments NanoFree packaging technology for compact footprint integration

Latches Applications

• I/O port expansion circuits
• Buffer register implementations
• Bidirectional bus driver applications

Latches Procurement Notes

Verify the specific suffix 'DCKR' corresponds to the SC-70-6 package variant and reel/cut-tape availability. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the ordering part number matches the required tape and reel quantity specifications for your manufacturing process.

Latches Selection Notes

Select this component for designs requiring a single-channel D-latch with wide voltage compatibility ranging from 1.65 V to 5.5 V. Consider its low static current consumption and robust output drive strength for efficient power management. Verify that the SC-70-6 package dimensions fit your PCB layout constraints and thermal requirements.
