Overview
The SN74ABT16373ADGGRG4 is a 16-bit transparent D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features non-inverting logic with three-state outputs. The device provides a propagation delay of 5.4 ns at 5 V, with low-level output current capability of 32 mA and high-level output current of -32 mA. It is housed in a TSSOP-48 package and supports surface mount installation. The component functions across an operating temperature range from -40°C to +85°C.
Feature Summary
- Provides 16-bit data storage via transparent D-type latching mechanism
- Features three-state outputs for bus-oriented memory operations
- Supports non-inverting logic polarity for direct signal transmission
Applications
- Bus-oriented memory register implementations
- Temporary storage of address or data information on system buses
- Parallel-to-serial conversion circuits requiring latched input states
Procurement Notes
Verify the complete part number including the G4 suffix to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm that the TSSOP-48 package matches your PCB footprint requirements. Check datasheet specifications for static current and power dissipation limits relative to your thermal design constraints before finalizing procurement.
Selection Notes
Select this component when a 5 V logic family solution is required for high-speed 16-bit latching applications. The ABT series offers faster propagation delays compared to standard ALS or LVC families while maintaining robust drive currents. Ensure the operating environment stays within the specified -40°C to +85°C temperature range and that the supply voltage remains strictly between 4.5 V and 5.5 V.
Part Context
This part belongs to the SN74ABT16373A series of 16-bit transparent latches. It is the RoHS-compliant, lead-free version (indicated by the G4 suffix) of the SN74ABT16373ADGGR. The device is designed for high-performance digital systems requiring reliable data retention and fast switching speeds in a compact surface-mount package.
