74191 Up/Down Binary Counter 5V 65mA IC DIP-16

Description

74191 Up/Down Binary Counter 5V 65mA IC DIP-16 The 74191 Up/Down Binary Counter is a synchronous digital logic integrated circuit designed to count binary values from 0 to 15. It supports both upward and downward counting, with direction controlled by a dedicated input. Its synchronous architecture allows the counter stages to update together in response to the clock signal. The IC includes parallel data inputs for presetting a starting count, along with control and status outputs useful for cascading counters and building larger counting systems. The DIP-16 through-hole package makes it suitable for PCB assembly, digital logic experiments, frequency dividers, and electronic control applications.
