74ALVT16373DL,118

Overview

The 74ALVT16373DL,118 is a 16-bit D-type transparent latch with 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 2.3V to 2.7V and 3V to 3.6V. The device features a propagation delay of 2ns and output currents of 8mA (high) and 24mA/32mA/64mA (low). It is housed in a 48-TSSOP package and functions as two independent 8-bit latches or one 16-bit latch.

Feature Summary

• Transparent data storage allowing direct input-to-output passage when enabled
• Three-state outputs for bus line sharing and isolation
• Dual enable architecture supporting independent 8-bit or combined 16-bit operation

Applications

• High-speed data buffering in digital systems
• Parallel interface data latching
• Memory address/data register stages

Procurement Notes

Verify the specific suffix '118' corresponds to the tape and reel packaging configuration required for automated assembly. Confirm the 48-TSSOP footprint matches the target PCB design. Ensure the 2.3V-3.6V operating voltage aligns with the system power rails. Check RoHS3 compliance status for environmental regulations.

Selection Notes

Select this component for applications requiring high-speed latching with low propagation delay. The ALVT series offers strong drive capability suitable for driving transmission lines. Consider the 48-pin package density for space-constrained designs. Verify compatibility with system logic levels and power supply constraints before integration.

Part Context

This part belongs to the 74ALVT logic family, designed for 2.5V and 3.3V applications. It provides high speed and low power consumption compared to older LVT standards. The transparent latch function is essential for synchronizing data flow in complex digital circuits.

Replacement Considerations

The SN74ALVTH16373DL from Texas Instruments is a documented alternative. Verify pinout compatibility and electrical specifications before substitution.
