SN74F163ADR

Counter Dividers Overview

The SN74F163ADR is a synchronous, presettable 4-bit binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device features internal carry look-ahead circuitry for high-speed counting applications. It utilizes a buffered clock input that triggers flip-flops on the rising edge, ensuring simultaneous output changes to eliminate counting spikes. The component is housed in a 16-pin SOIC package and is supplied in tape and reel format.

Counter Dividers Feature Summary

• Internal carry look-ahead circuitry enables high-speed counting without additional external gating.
• Fully synchronous operation ensures all flip-flops are clocked simultaneously to prevent output counting spikes.
• Synchronous clear and load functions allow easy modification of count length and presetting to any value between 0 and 15.

Counter Dividers Applications

• High-speed counting designs requiring fast propagation
• N-bit cascading applications utilizing ripple-carry outputs
• Programmable counters with synchronous preset capabilities

Counter Dividers Procurement Notes

Verify the active production status and RoHS compliance directly with Texas Instruments before procurement. Confirm the specific tape and reel packaging details and moisture sensitivity level ratings required for your assembly process. Ensure the ordering suffix matches the desired package type and quantity specifications.

Counter Dividers Selection Notes

Select this component when synchronous operation is required to avoid the timing issues associated with asynchronous ripple counters. The internal carry look-ahead makes it suitable for designs demanding higher clock frequencies compared to standard counters. Verify that the logic family characteristics align with the system's power and speed requirements.

Counter Dividers Part Context

This part belongs to the SN74F163A series of synchronous 4-bit binary counters. It is distinct from asynchronous variants by its simultaneous clocking mechanism. The 'DR' suffix indicates the SOIC package variant supplied in a tape and reel configuration, distinguishing it from tube-packaged versions like the SN74F163AD.
