74ALVCH16373DL,112

Overview

The Nexperia 74ALVCH16373DL,112 is a 16-bit D-type transparent latch with bus hold inputs and 3-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and supports temperatures from -40 °C to +85 °C. The device features two latch enables (1LE and 2LE) and two output enables (1OE and 2OE), each controlling 8 bits. Propagation delay ranges from 1.0 ns to 5.9 ns depending on voltage. Output drive capability reaches ±24 mA at 3.0 V.

Feature Summary

• Bus hold inputs prevent floating states
• IOFF circuitry prevents backflow current during partial power-down
• MULTIBYTE flow-through architecture for standard pin-out compatibility

Applications

• Parallel data storage in high-speed digital systems
• Interface buffering between microprocessors and memory modules
• Data latching in communication equipment

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the application environment remains within the specified temperature and voltage limits. Ensure ESD protection measures are adequate for the installation site. Check for any recent product change notices affecting the manufacturing site or specifications.

Selection Notes

Select this component when a 16-bit transparent latch with 3-state outputs is required. The bus hold feature simplifies input handling. Verify that the operating voltage aligns with the system's power rails. Consider the TSSOP48 package dimensions for PCB layout constraints.

Part Context

This part belongs to the 74ALVCH series of advanced low-voltage CMOS logic devices. It provides high-speed performance suitable for modern digital applications. The device is designed to interface directly with TTL levels while maintaining low power consumption.

Replacement Considerations

Check for direct pin-compatible alternatives within the same logic family. Verify electrical characteristics match the original design requirements. Ensure the replacement package type is available in the desired quantity.
