MC74HC573N is a high-speed octal transparent latch with 3-state outputs, manufactured by Motorola/ON Semiconductor (MOTO/NS).

The MC74HC573N is a high-speed octal transparent latch with 3-state outputs, manufactured by Motorola/ON Semiconductor (MOTO/NS).

Specifications:

  • Logic Type: Octal D-Type Transparent Latch
  • Output Type: 3-State
  • Number of Bits: 8
  • Supply Voltage Range: 2V to 6V
  • High-Level Output Current: -7.8mA
  • Low-Level Output Current: 7.8mA
  • Propagation Delay Time: 13ns (typical at 5V)
  • Operating Temperature Range: -40°C to +85°C
  • Package Type: PDIP-20 (Plastic Dual In-Line Package)
  • Latch Enable (LE) Input: Active High
  • Output Enable (OE) Input: Active Low

Descriptions:

The MC74HC573N is designed for bus-oriented applications, allowing data to be latched when the Latch Enable (LE) input is high. The outputs are controlled by an Output Enable (OE) input, which, when low, allows the data to appear on the outputs. When OE is high, the outputs are in a high-impedance state.

Features:

  • High-speed CMOS technology
  • Low power consumption
  • Balanced propagation delays
  • 3-state outputs for bus interfacing
  • TTL-compatible inputs
  • Wide operating voltage range (2V to 6V)
  • Output drive capability: 10 LSTTL loads

This latch is commonly used in microprocessor and microcontroller systems for data storage and bus driving applications.
