PI74VCX16373A

Latches Overview

The PI74VCX16373A is a 16-bit transparent D-type latch with 3-state outputs manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.8V to 3.6V and features I/O tolerance up to 3.6V, supporting mixed-signal environments. The device contains two independent octal latches, providing balanced ±24mA drive capability. It utilizes patented noise reduction circuitry to minimize output ground bounce and undershoot. The component is housed in a 48-pin TSSOP package and supports live insertion for system upgrades.

Latches Feature Summary

• Supports live insertion into active systems without disrupting operation
• Features patented noise reduction circuitry for low ground bounce
• Provides balanced high-current drive capability for bus lines
• Ensures power-off high-impedance state for inputs and outputs

Latches Applications

• Buffer registers in digital logic circuits
• I/O port expansion modules
• Bidirectional bus drivers
• Working registers in data processing systems

Latches Procurement Notes

Verify the specific ordering suffix 'A' corresponds to the standard 48-pin TSSOP package configuration. Confirm that the procurement source provides the Pb-free and Green compliant version if environmental regulations require it. Ensure the supplier documentation matches the PI74VCX16373A part number exactly to avoid confusion with similar VCX family members.

Latches Selection Notes

Select this component when designing systems requiring 16-bit data storage with tri-state control. It is suitable for applications needing interface between 1.8V and 3.6V logic domains due to its I/O tolerance. Consider this device for designs prioritizing signal integrity through reduced ground bounce and undershoot characteristics compared to standard CMOS latches.

Latches Part Context

This component belongs to the PI74VCX family of low-voltage logic devices from Diodes Incorporated (formerly Pericom). The family is designed for modern portable and battery-operated electronics requiring efficient power management. The 16373 variant specifically addresses the need for wide-width latching with high-speed performance in compact surface-mount packages.
