74HCT373D – PHILIPS

Overview

The Nexperia 74HCT373D is an octal D-type transparent latch designed for robust digital signal buffering and data holding in 5V CMOS systems. Its key operational characteristic is the transparent latching mechanism, allowing data to pass through to the output when the enable input is active, and retaining the last state when inactive. A critical design consideration for this device is managing the propagation delay, which, at 14ns, can impact maximum clock frequencies in high-speed synchronous designs, necessitating careful timing analysis to avoid setup and hold time violations.

Key Features

• Octal D-type transparent latch
• 8:8 data bus architecture
• Tri-state output capability
• 4.5V to 5.5V supply voltage range
• 14ns maximum propagation delay
• 20-SOIC (0.295″, 7.50mm Width) surface mount package

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

• Data buffering in embedded system memory interfaces
• Output stage for microcontrollers requiring high-impedance states
