MM74HC373N is a high-speed octal transparent latch with 3-state outputs, manufactured by National Semiconductor (NS).

The MM74HC373N is a high-speed octal transparent latch with 3-state outputs, manufactured by National Semiconductor (NS).

Specifications:

  • Logic Family: HC (High-Speed CMOS)
  • Number of Bits: 8 (Octal)
  • Latch Type: Transparent
  • Output Type: 3-State
  • Supply Voltage Range: 2V to 6V
  • High-Level Input Voltage (Min): 2V
  • Low-Level Input Voltage (Max): 0.8V
  • Operating Temperature Range: -40°C to +85°C
  • Package Type: PDIP-20 (Plastic Dual In-Line Package)
  • Propagation Delay: Typically 13ns at 5V
  • Output Current: ±6mA
  • Input Capacitance: 3.5pF (Typical)

Descriptions:

The MM74HC373N is an octal D-type transparent latch featuring 3-state outputs. It is designed for bus-oriented applications, allowing data to be latched when the latch enable (LE) input is high. When the output enable (OE) is low, the outputs are active; when OE is high, the outputs are in a high-impedance state.

Features:

  • High-Speed Operation: Compatible with TTL levels
  • 3-State Outputs: Allows bus connection
  • Wide Operating Voltage Range: 2V to 6V
  • Low Power Consumption: CMOS technology
  • Balanced Propagation Delays
  • Direct Interface with TTL, NMOS, and CMOS

This device is commonly used in memory address latching, data buffering, and bus interfacing applications.

(Note: Always refer to the official datasheet for precise details.)
