74ALVCH162373TX

Latches Overview

The Fairchild Semiconductor 74ALVCH162373TX is a low-voltage, high-speed CMOS device containing sixteen non-inverting transparent latches with three-state outputs. Designed for bus-oriented applications, it features byte control to manage data flow efficiently. The component operates within a supply voltage range of 1.65 V to 3.6 V and supports a wide operating temperature range from -40°C to +85°C. It utilizes a TSSOP-48 surface-mount package, ensuring compatibility with modern PCB layouts while maintaining signal integrity in high-density digital systems.

Latches Feature Summary

• Contains sixteen non-inverting transparent latches with three-state outputs for efficient bus management
• Features byte control architecture to optimize data handling in parallel interfaces
• Incorporates bus hold functionality on data inputs to eliminate the need for external pull-up or pull-down resistors

Latches Applications

• Bus-oriented digital systems requiring parallel data storage
• High-speed memory interface circuits
• Data acquisition systems with byte-controlled input requirements

Latches Procurement Notes

Verify the specific manufacturer source, as this component may be listed under ON Semiconductor following corporate restructuring. Confirm the lifecycle status, as some listings indicate an obsolete or end-of-life condition. Ensure the package type matches the required TSSOP-48 footprint and check for RoHS compliance documentation before finalizing procurement decisions.

Latches Selection Notes

Select this component when designing systems that require sixteen-bit parallel latching with tri-state output capability. It is suitable for applications demanding low power consumption and operation at supply voltages between 1.65 V and 3.6 V. Consider the byte control feature if the design requires managing data in 8-bit segments rather than full 16-bit words simultaneously.

Latches Part Context

This part belongs to the ALVCH family of low-voltage CMOS logic devices, which are optimized for high-speed performance and low power dissipation. The 74ALVCH162373TX is functionally similar to other 16-bit latch variants but offers specific voltage and speed characteristics tailored for modern low-voltage digital environments. It serves as a critical interface element in systems bridging different voltage domains.

Latches Replacement Considerations

Direct substitutes include the 74VCX162373MTD and 74LCX162373MEA. Verify pinout compatibility and electrical specifications, particularly supply voltage ranges and drive strengths, before substituting. Note that the 74LCX variant may have different switching characteristics compared to the ALVCH series.
