M74HC590B1** is a high-speed CMOS 8-bit binary counter with output registers, manufactured by **STMicroelectronics (ST)**.

The M74HC590B1 is a high-speed CMOS 8-bit binary counter with output registers, manufactured by STMicroelectronics (ST).

Key Specifications:

  • Logic Family: HC (High-Speed CMOS)
  • Supply Voltage Range: 2V to 6V
  • Operating Temperature Range: -40°C to +125°C
  • Output Current: ±5.2mA
  • Propagation Delay: 18ns (typical at 5V)
  • Package Type: DIP-16 (Plastic Dual In-Line)
  • Pin Count: 16

Descriptions:

  • 8-bit synchronous binary counter with a storage register.
  • Parallel outputs are latched, while the counter continues operation.
  • Master Reset (MR) clears the counter but not the output register.
  • Output Enable (OE) controls the tri-state outputs.
  • Clock (CP) and Register Clock (RCK) operate independently.

Features:

  • Synchronous counting with asynchronous master reset.
  • Separate clock inputs for counter and register.
  • Tri-state outputs for bus-oriented applications.
  • Low power consumption (typical CMOS technology).
  • Compatible with TTL input/output levels.

This IC is commonly used in digital counting, frequency division, and data storage applications.
