HC161 is a high-speed CMOS 4-bit binary counter manufactured by Texas Instruments (TI).

The HC161 is a high-speed CMOS 4-bit binary counter manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features:

Specifications:

  • Logic Family: HC (High-Speed CMOS)
  • Supply Voltage Range: 2V to 6V
  • Operating Temperature Range: -40°C to +85°C
  • Maximum Clock Frequency: ~50 MHz (at 5V)
  • Low Power Consumption: Typically a few µA in static mode
  • Output Drive Capability: 10 LSTTL loads
  • Propagation Delay: ~10 ns (typical at 5V)
  • Package Options: PDIP, SOIC, TSSOP

Description:

The HC161 is a synchronous 4-bit binary counter with an asynchronous reset. It features parallel load capability, allowing preset data to be loaded when the load input is active. The counter advances on the rising edge of the clock signal when enabled.

Features:

  • Synchronous Counting: Operates with a clock signal for precise timing.
  • Asynchronous Reset: Clears all outputs to zero independently of the clock.
  • Parallel Load: Allows preloading a 4-bit value via data inputs.
  • Carry Output: Provides a ripple carry signal for cascading multiple counters.
  • High Noise Immunity: CMOS technology ensures robust performance.
  • Wide Operating Voltage: Supports 2V to 6V, making it versatile for various applications.

This information is based on TI's official datasheet for the HC161. For detailed electrical characteristics and timing diagrams, refer to the manufacturer's documentation.
