CD74HC163E

Counter Dividers Overview

The CD74HC163E is a high-speed CMOS logic integrated circuit manufactured by Harris Corporation, functioning as a 4-bit binary counter with synchronous reset. It operates within a supply voltage range of 2V to 6V and supports clock speeds up to 35MHz. The device is housed in a 16-pin DIP package and is designed for operation across an extended temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Synchronous preset capability allowing parallel data loading
• Synchronous reset function for precise control
• High-speed CMOS technology for low power consumption

Counter Dividers Applications

• Digital counting systems
• Frequency division circuits
• Timing sequence generators

Counter Dividers Procurement Notes

Verify the manufacturer origin, as this component was produced by both Harris Corporation and Texas Instruments. Confirm the specific suffix 'E' corresponds to the 16-DIP package and lead-free status if required. Check RoHS compliance history, as older Harris batches may not meet current environmental standards. Ensure the part number matches the exact functional specifications needed for your design.

Counter Dividers Selection Notes

Select this component when a 4-bit synchronous binary counter with preset functionality is required. It is suitable for designs needing operation at voltages between 2V and 6V. Consider the 16-DIP package for through-hole assembly needs. Verify compatibility with existing logic families and ensure the 35MHz speed meets system timing requirements.

Counter Dividers Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. It is a variant of the standard 74HC163 architecture, originally developed by Harris Corporation before its semiconductor assets were acquired by Texas Instruments. The 'E' suffix typically denotes the plastic DIP package option.

Counter Dividers Replacement Considerations

Compatible substitutes include the Texas Instruments CD74HC163E and generic 74HC163 equivalents from other manufacturers. Ensure pinout compatibility and verify that the replacement maintains the same synchronous reset and preset features.
