Overview

The PI74FCT162373ATV is a 16-bit transparent latch designed for bus-oriented applications. It is part of Pericom Semiconductor's advanced 0.6 micron CMOS technology logic circuits, offering high speed and low power consumption with high current drive capabilities.

Key Features

• High-speed, low power devices with high current drive.
• Vcc = 5V ±10%.
• Hysteresis on all inputs.
• Available in 48-pin 240 mil wide plastic TSSOP (A) and 48-pin 300 mil wide plastic SSOP (V) packages.

Product Description

The PI74FCT162373ATV is designed with balanced output drivers that provide ±24 mA current drive. It includes current limiting resistors at its outputs to control the output edge rate, resulting in lower ground bounce and undershoot. This feature eliminates the need for external terminating resistors for most interface applications.
