CD40193BE

Counter Dividers Overview

The CD40193BE is a synchronous, positive edge-triggered, 4-bit bidirectional binary counter from the 4000/14000/40000 series. It utilizes CMOS technology and features separate clocks for up and down counting operations. The device supports asynchronous reset and parallel load functions. It operates within a supply voltage range of 3 V to 18 V and withstands operating temperatures from -55 °C to 125 °C. The component is housed in a 16-pin DIP package.

Counter Dividers Feature Summary

• Synchronous operation with positive edge triggering for both up and down counting directions.
• Dual clock inputs allow independent control of count direction without external gating logic.
• Asynchronous master reset and synchronous parallel load capabilities for flexible state management.

Counter Dividers Applications

• Digital frequency division circuits
• Timekeeping and digital clock systems
• Event counting applications

Counter Dividers Procurement Notes

Verify the manufacturer origin carefully, as Texas Instruments holds the primary rights to the CD40193BE designation. Harris Corporation documentation may refer to legacy or specific regional variants. Confirm RoHS compliance status and exact pinout compatibility before integration, as packaging suffixes can indicate significant electrical or mechanical differences between production eras.

Counter Dividers Selection Notes

Select this component when a bidirectional synchronous counter is required with minimal external logic. The dual-clock architecture simplifies design compared to single-clock reversible counters. Ensure the system power supply remains stable within the 3 V to 18 V range to maintain timing integrity across the full industrial temperature spectrum.

Counter Dividers Part Context

This part belongs to the standard 4000-series CMOS logic family, known for wide voltage tolerance and high noise immunity. While Texas Instruments is the dominant producer of the CD40193BE, historical data indicates Harris Corporation also manufactured compatible versions under similar naming conventions, often sharing identical functional specifications and pinouts.
