74ALVT16373DGG,518

Overview

The Nexperia 74ALVT16373DGG,518 is a 16-bit transparent D-type latch with 3-state outputs, housed in a 48-lead TSSOP package (SOT362-1). It operates within a supply voltage range of 2.3 V to 3.6 V and supports an operating temperature from -40 °C to +85 °C. The device features BiCMOS technology for high speed and output drive capabilities, including +64 mA/–32 mA output current. It includes bus-hold inputs, power-up reset, and IOFF circuitry for partial power-down mode operation.

Feature Summary

• BiCMOS high-speed performance with 3-state buffers
• Bus-hold data inputs eliminate external pull-up resistors
• IOFF circuitry enables partial power-down mode operation
• Power-up 3-state functionality prevents initial bus loading

Applications

• Parallel data storage in high-speed digital systems
• Interface bridging between different voltage domains
• Buffering and latching operations in communication buses

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration. Confirm that the component meets RoHS3 compliance standards. Ensure the selected package variant aligns with the PCB footprint specifications for the SOT362-1 outline. Cross-reference the manufacturer's latest datasheet revision to confirm all electrical characteristics remain unchanged.

Selection Notes

Select this component when a 16-bit latch with 3-state outputs is required for 2.5 V or 3.3 V logic systems. The BiCMOS technology provides superior drive strength compared to standard CMOS alternatives. Verify that the input voltage tolerance up to 5.5 V matches the source signal levels. Consider the thermal management requirements for the TSSOP48 package in dense layouts.

Part Context

This part belongs to the 74ALVT series, designed for low-voltage applications requiring high performance. The ALVT family utilizes BiCMOS technology to achieve speeds comparable to older high-voltage families while operating at lower voltages. The 16373 variant specifically provides 16-bit latching capability with independent control sections.

Replacement Considerations

Check for direct pin-compatible substitutes such as the SN74ALVTH16373DL from Texas Instruments. Verify that any replacement maintains the same 3-state output behavior and voltage compatibility. Ensure the alternative device supports the required bus-hold and IOFF features if these are critical to the design.
