74LVCH16373APAG

Latches Overview

The IDT74LVCH16373APAG is a 16-bit transparent D-type latch manufactured by Renesas Electronics under the IDT brand. It operates within a voltage range of 1.65 V to 3.6 V and features three-state outputs for bus-oriented applications. The device utilizes LVCH logic series technology and is housed in a TSSOP-48 package. It includes bus hold functionality on data inputs to eliminate external pull-up resistors. The component supports mixed-mode signal operations, allowing interfacing with 5 V devices while operating at lower supply voltages.

Latches Feature Summary

• Provides 16-bit transparent latching with separate enable controls for each octal section
• Features three-state outputs suitable for high-speed bus architectures
• Incorporates bus hold circuitry to maintain input states without external components
• Supports mixed-mode operation between 3.3 V and 5 V logic levels

Latches Applications

• Bus-oriented memory address latching systems
• I/O port buffering in mixed-voltage environments
• High-speed data storage in portable electronic devices
• Temporary data holding in communication interfaces

Latches Procurement Notes

This component is officially discontinued and marked as End-of-Life (EOL) by the manufacturer. Current availability is restricted, with some distributors reporting limited stock or no sales in certain regions. Verification of genuine sourcing is critical due to potential obsolescence. Buyers should confirm the specific manufacturing date code and check for valid RoHS compliance documentation before procurement. Alternative sources may only offer surplus inventory rather than new production units.

Latches Selection Notes

Engineers selecting this part must account for its discontinued status when designing long-term products. The device offers low power consumption and wide supply voltage flexibility, making it suitable for battery-operated equipment. Its TSSOP-48 package requires appropriate PCB footprint design. Designers should evaluate current market availability against projected production volumes to mitigate supply chain risks associated with obsolete logic families.

Latches Part Context

The 74LVCH16373A belongs to the LVCH logic family, designed for low-voltage CMOS applications. This specific part number represents the 16-bit variant packaged in TSSOP-48. It serves as a successor to older ABT functions, offering improved speed and reduced power dissipation. The IDT branding indicates its origin from Integrated Device Technology, now part of Renesas Electronics.
