SN74F163ANE4

Counter Dividers Overview

The SN74F163ANE4 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 counting, loading, and clearing functions. Recommended operating conditions specify a supply voltage (VCC) of 4.5 V to 5.5 V and an operating temperature range of 0°C to 70°C. Maximum clock frequency is rated at 90 MHz under maximum voltage conditions.

Counter Dividers Feature Summary

• Internal carry look-ahead circuitry enables fast n-bit cascading without external gating logic.
• Fully synchronous operation ensures all flip-flops are clocked simultaneously to eliminate output counting spikes.
• Synchronous preset capability allows data loading coincident with the clock pulse regardless of enable inputs.
• Independent clock circuit isolates mode changes from existing counter contents until the next clock transition.

Counter Dividers Applications

• High-speed digital counting designs requiring minimal propagation delay.
• N-bit cascaded counter systems utilizing internal carry look-ahead.
• Programmable timing circuits using synchronous clear or load functions.
• Digital state machines requiring precise synchronous data updates.

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'E4' against current Texas Instruments documentation to confirm lead-free compliance and RoHS status. Confirm package availability as manufacturing statuses may change. Ensure the procurement channel provides valid traceability for the PDIP-16 tube packaging format specified in the datasheet.

Counter Dividers Selection Notes

Select this component when synchronous operation is required to prevent ripple-clock glitches common in asynchronous counters. The internal carry look-ahead makes it suitable for applications demanding higher counting speeds than standard ripple counters provide. Verify that the 4.5 V to 5.5 V supply range aligns with the system power architecture.

Counter Dividers Part Context

This part belongs to the SN74F163A family of synchronous 4-bit binary counters manufactured by Texas Instruments. It utilizes the F logic series technology, offering faster switching characteristics compared to LS or HC variants. The device is housed in a standard 16-pin PDIP package designed for through-hole mounting on printed circuit boards.

Counter Dividers Replacement Considerations
