SN74F163ANG4

Counter Dividers Overview

The SN74F163ANG4 is a synchronous, presettable 4-bit binary counter from the Texas Instruments SN74F163A series. It operates on a positive-going clock edge and features internal carry look-ahead circuitry for high-speed cascading. The device supports fully synchronous clear and load functions, allowing count modification without output spikes. Recommended operating conditions specify a supply voltage of 4.5 V to 5.5 V and an operating temperature range of 0°C to 70°C.

Counter Dividers Feature Summary

• Internal carry look-ahead circuitry enables fast counting and n-bit cascading without additional gating logic.
• Fully synchronous operation ensures all flip-flops are clocked simultaneously, eliminating output counting spikes associated with asynchronous counters.
• Synchronous clear and load inputs allow the counter to be reset or preset to any value between 0 and 15 coincident with the clock pulse.

Counter Dividers Applications

• High-speed digital counting designs requiring precise timing synchronization
• N-bit cascaded counter systems utilizing internal carry look-ahead
• Programmable frequency dividers and timing circuits

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'G4' against current Texas Instruments documentation, as standard datasheets list variants such as SN74F163AN. Confirm package type, lead finish, and RoHS compliance status directly with the manufacturer or authorized distributors to ensure compatibility with current production standards and environmental regulations.

Counter Dividers Selection Notes

Select this component for applications requiring synchronous 4-bit binary counting with minimal propagation delay. The internal carry look-ahead reduces cascading complexity compared to ripple-carry alternatives. Ensure the design environment stays within the 0°C to 70°C temperature range and utilizes a 5 V power supply for optimal electrical characteristics.

Counter Dividers Part Context

This part belongs to the SN74F163A family of synchronous 4-bit binary counters. It is distinct from asynchronous (ripple) counters by its simultaneous flip-flop triggering. The device is designed for use in digital logic systems where predictable timing and high-speed operation are critical requirements.

Counter Dividers Replacement Considerations

Direct substitutes include SN74F163AD and SN74F163AN. Verify pinout compatibility and electrical specifications before substitution.
