74ALVT16373DGG,112

Overview

The Nexperia 74ALVT16373DGG,112 is a 16-bit transparent D-type latch with 3-state outputs housed in a 48-lead TSSOP package. It operates within a supply voltage range of 2.3 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device supports output drive capabilities of +64 mA and -32 mA, ensuring compatibility with 5 V systems and TTL levels. It includes bus-hold data inputs to eliminate external pull-up resistors for unused lines.

Feature Summary

• BiCMOS technology providing high speed and robust output drive capability
• Bus-hold data inputs that maintain logic states without external components
• IOFF circuitry enabling partial power-down mode operation
• Power-up reset and 3-state functionality to prevent initial bus loading

Applications

• High-speed data latching in digital communication interfaces
• Buffering and driving parallel data buses in computing systems
• Interface bridging between low-voltage logic and 5 V tolerant peripherals

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity and packaging variant. Confirm the component status remains active for production use. Ensure the selected package version aligns with the PCB footprint specifications for the SOT362-1 outline.

Selection Notes

Select this component when designing circuits requiring 16-bit storage with simultaneous tri-state control. The wide supply voltage range accommodates both 2.5 V and 3.3 V logic families. The overvoltage tolerance simplifies interfacing with legacy 5 V buses without additional level shifting hardware.

Part Context

This part belongs to the 74ALVT series of advanced low-voltage TTL-compatible logic devices. It serves as a high-performance alternative to standard LVT latches, offering faster propagation delays and higher current drive. The device is manufactured using BiCMOS processes to balance speed and power consumption effectively.

Replacement Considerations

Check for pin-compatible alternatives such as the 74LVT16373ADL from Nexperia or equivalent parts from other manufacturers. Verify that substitute devices meet the same 64 mA/32 mA output drive requirements and 5.5 V input tolerance specifications.
