CD74AC163E-NG

Counter Dividers Overview

The CD74AC163E-NG is a 4-bit synchronous binary counter from the Texas Instruments AC logic family, housed in a 16-pin PDIP package. It features internal carry look-ahead for high-speed counting and supports parallel presetting via synchronous LOAD inputs. The device operates on a supply voltage range of 1.5 V to 5.5 V with an operating temperature range of -55°C to 125°C. It includes synchronous clear functionality and ripple-carry outputs (RCO) for cascading multiple stages without external gating.

Counter Dividers Feature Summary

• Synchronous operation eliminates output counting spikes associated with ripple-clock counters by clocking all flip-flops simultaneously.
• Internal carry look-ahead circuitry enables fast n-bit cascading applications without additional external gating components.
• Fully programmable architecture allows presetting to any value between 0 and 15 synchronously with the clock pulse.

Counter Dividers Applications

• High-speed synchronous counting designs requiring precise timing control
• Cascaded multi-stage digital counters utilizing internal carry look-ahead
• Programmable frequency dividers and event counters

Counter Dividers Procurement Notes

Verify that the ordering suffix 'NG' aligns with the standard catalog designation CD74AC163E in the PDIP-16 tube configuration. Confirm the specific manufacturer source matches the datasheet documentation. Ensure compatibility with the specified -55°C to 125°C industrial temperature range and 1.5 V to 5.5 V supply requirements before finalizing procurement.

Counter Dividers Selection Notes

Select this component when synchronous reset and parallel load capabilities are required within a 4-bit binary counting application. The AC logic series offers balanced propagation delay characteristics suitable for moderate-speed digital systems. Consider the PDIP-16 through-hole package if prototyping or legacy board layouts necessitate non-surface mount integration.

Counter Dividers Part Context

This device belongs to the CD74AC163 family of 4-bit synchronous binary counters manufactured by Texas Instruments. It shares functional similarities with the CD74AC161 but differs in its reset mechanism, offering synchronous clear instead of asynchronous. The part is designed for general-purpose digital logic applications requiring reliable, glitch-free counting operations.

Counter Dividers Replacement Considerations

CD74AC163E serves as the direct equivalent for the CD74AC163E-NG variant. For alternative sourcing, verify cross-compatibility with other manufacturers producing 74AC163 devices, ensuring pinout and electrical specifications match the original design requirements.
