M74HC190RM13TR

Counter Dividers Overview

The M74HC190RM13TR is a high-speed CMOS 4-bit synchronous up/down counter fabricated with silicon gate C2MOS technology. It operates within a supply voltage range of 2V to 6V and features asynchronous parallel load, count enable, and direction control inputs. The device provides MAX/MIN terminal count and Ripple Clock outputs for multi-stage applications. It is housed in a 16-pin SOIC package.

Counter Dividers Feature Summary

• Synchronous state changes triggered by the LOW-to-HIGH transition of the clock pulse input.
• Asynchronous parallel load input overrides counting to preset data from the DATA inputs.
• Direction control input determines whether the circuit counts up or down.
• MAX/MIN and Ripple Clock outputs provide overflow/underflow indication.

Counter Dividers Applications

• Programmable counters
• Multi-stage counter systems requiring carry/borrow signal generation
• Digital timing circuits

Counter Dividers Procurement Notes

Counter Dividers FAQ

How does the asynchronous parallel load function interact with the counting process?

The asynchronous parallel load input overrides the counting sequence. When activated, it immediately loads the steady-state data present on the DATA inputs into the flip-flops, regardless of the clock signal.

What is the purpose of the Ripple Clock output?

The Ripple Clock output facilitates the generation of carry/borrow signals in multi-stage counter applications, allowing for cascading multiple counters efficiently.
