74HC573A** is a high-speed octal transparent latch with 3-state outputs, manufactured by **Toshiba (TOS)**.

The 74HC573A is a high-speed octal transparent latch with 3-state outputs, manufactured by Toshiba (TOS).

Key Specifications:

  • Logic Type: Octal D-type transparent latch
  • 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
  • Propagation Delay (max): 24 ns at 4.5V
  • Output Current (High/Low): ±7 mA at 4.5V
  • Latch-Up Performance: Exceeds 250 mA

Descriptions:

The 74HC573A is an 8-bit transparent latch with 3-state outputs. It features a latch enable (LE) input and an output enable (OE) input. When LE is high, data passes through to the outputs. When LE is low, the data is latched. The outputs can be disabled using the OE input.

Features:

  • High-Speed Operation: Suitable for high-performance applications
  • Low Power Consumption: CMOS technology ensures low power dissipation
  • 3-State Outputs: Allows bus-oriented applications
  • Wide Operating Voltage Range: 2V to 6V
  • Pin-Compatible with 74LS573: Drop-in replacement for LS-TTL versions
  • ESD Protection: HBM: 2000V, MM: 200V

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