SN74HC163DR

Counter Dividers Overview

The SN74HC163DR is a 4-bit synchronous binary counter from the Texas Instruments SN74HC163 series. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40°C to +85°C. The device features a synchronous reset mechanism and counts in an upward direction on the positive edge of the clock signal. It is housed in a 16-SOIC surface-mount package with a maximum counting rate of 36 MHz.

Counter Dividers Feature Summary

• Synchronous four-bit binary up-counter architecture
• Positive-edge triggered clock input for precise timing control
• Synchronous clear function allowing controlled reset operations

Counter Dividers Applications

• Digital frequency division circuits
• Sequential logic state machines
• Timing pulse generation systems

Counter Dividers Procurement Notes

Verify the specific suffix 'DR' corresponds to the SOIC-16 package and tape-and-reel shipping configuration. Confirm RoHS compliance status and ensure the component meets the required industrial temperature specifications for the intended application environment before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter is required with a wide voltage operating range. It is suitable for designs needing positive-edge triggering and synchronous reset capabilities. Ensure the design accommodates the 16-SOIC footprint and thermal requirements for operation between -40°C and +85°C.

Counter Dividers Part Context

This part belongs to the SN74HC163 family of high-speed CMOS logic devices manufactured by Texas Instruments. The HC series offers compatibility with standard TTL logic levels while providing improved noise immunity and lower power consumption compared to older logic families, making it suitable for modern digital systems.
