74ALVT16373DGG,512

Overview

The Nexperia 74ALVT16373DGG,512 is a 16-bit transparent D-type latch with 3-state outputs housed in a TSSOP48 package. It operates on a supply voltage range of 2.3 V to 3.6 V and features BiCMOS technology for high speed and output drive capability. The device supports two independent 8-bit latches or a single 16-bit latch configuration. It includes bus-hold data inputs to eliminate external pull-up resistors and provides overvoltage tolerant inputs up to 5.5 V. The component ensures power-up reset and partial power-down mode operation via IOFF circuitry.

Feature Summary

• BiCMOS high-speed performance with strong output drive capability
• Bus-hold data inputs eliminate the need for external pull-up resistors
• Overvoltage tolerant inputs allow direct interface with 5 V systems
• IOFF circuitry enables partial power-down mode operation

Applications

• Parallel data storage in high-speed digital systems
• Interface between different voltage domains (e.g., 3.3 V to 5 V)
• Buffering and driving large capacitive loads

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel quantity. Confirm the package variant corresponds to the SOT362-1 designation. Ensure the temperature grade aligns with the -40 °C to +85 °C specification. Cross-reference the manufacturer part number against official Nexperia documentation to confirm authenticity and current production status.

Selection Notes

Select this component when a 16-bit transparent latch with 3-state outputs is required. It is suitable for applications needing direct interfacing with 5 V TTL levels while operating at lower supply voltages. Consider the BiCMOS technology for faster propagation delays compared to standard CMOS alternatives. Verify that the TSSOP48 package fits the available PCB footprint constraints.

Part Context

This device belongs to the Nexperia ALVT series, which combines the low power consumption of LVT with the high speed and drive strength of ALVT. The 74ALVT16373 is designed for demanding applications requiring fast data transfer and robust signal integrity. It is part of a broader family of logic ICs intended for complex digital system designs.

Replacement Considerations

Check for pin-compatible alternatives within the same ALVT family. Verify if other manufacturers offer equivalent 16-bit latches with similar 3-state output characteristics. Ensure any substitute maintains the required 5 V tolerance and BiCMOS performance levels.
