SN74HC163NE4

Counter Dividers Overview

The SN74HC163NE4 is a 4-bit synchronous binary counter from the Texas Instruments HC logic family. 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 internal carry look-ahead for high-speed counting, synchronous preset capability, and a ripple-carry output (RCO) for cascading. It utilizes a positive-edge-triggered clock input and includes synchronous clear and load functions.

Counter Dividers Feature Summary

• Synchronous operation with simultaneous flip-flop clocking eliminates output counting spikes.
• Internal carry look-ahead circuitry enables high-speed n-bit cascading without additional gating.
• Fully programmable design allows synchronous presetting to any value between 0 and 15.

Counter Dividers Applications

• High-speed binary counting designs
• n-bit synchronous counter cascading
• Modulo-N frequency division

Counter Dividers Procurement Notes

Verify the specific package type and lead finish against the datasheet ordering information. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement. Ensure the selected variant matches the required operating temperature range and pinout configuration for the target application.

Counter Dividers Selection Notes

Select this component for applications requiring synchronous counting with minimal propagation delay variations. The internal carry look-ahead makes it suitable for multi-stage cascaded counters where speed is critical. Verify that the system voltage falls within the 2 V to 6 V operational range and that the load capacitance requirements are met.

Counter Dividers Part Context

This part belongs to the SN74HC163 series of 4-bit synchronous binary counters. It is manufactured by Texas Instruments in the PDIP-16 package. The 'E4' suffix indicates environmental compliance and lead finish specifications consistent with Texas Instruments manufacturing standards for this product line.

Counter Dividers Replacement Considerations

SN74HC163N is the non-environmental compliant equivalent in the same PDIP-16 package. Other package variants such as SN74HC163DR or SN74HC163NSR offer different form factors but share identical logical functionality.
