PI74VCX16373AE

Latches Overview

The PI74VCX16373AE 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 supports industrial temperatures from -40°C to +85°C. The device features balanced ±24mA drive, I/O tolerance up to 3.6V, and patented noise reduction circuitry ensuring typical VOLP and VOHV below 0.6V at 2.5V. Propagation delay ranges from 0.6ns to 1.4ns depending on voltage. It is housed in a 48-pin TSSOP package.

Latches Feature Summary

• Supports live insertion and power-off high-impedance states
• Patented noise reduction circuitry minimizes ground bounce and undershoot
• I/O tolerant inputs and outputs for mixed-voltage systems
• Balanced output drive capability

Latches Applications

• Buffer registers
• Bidirectional bus drivers
• Working registers
• I/O ports

Latches Procurement Notes

Verify the component status as discontinued or obsolete through official manufacturer channels before procurement planning. Confirm that the specific 'E' suffix denotes Pb-free and Green packaging compliant with RoHS standards. Ensure the 48-pin TSSOP footprint matches the target PCB design requirements.

Latches Selection Notes

Select this component for low-voltage applications requiring transparent latching with 3-state control. It is suitable for mixed 1.8V/3.6V systems due to its I/O tolerance. Consider the propagation delay specifications relative to system timing constraints and verify the thermal performance for the intended operating environment.

Latches Part Context

This part belongs to the PI74VCX family designed for low voltage operation. Originally developed by Pericom Semiconductor Corporation, it is now produced under Diodes Incorporated. The device functions as two independent 8-bit latches or one 16-bit latch, providing flexible configuration for data storage and bus interfacing.
