MC74AC4040DR2G

Counter Dividers Overview

The MC74AC4040DR2G is a 12-stage binary ripple counter and serial-in/parallel-out shift register manufactured by onsemi. It operates within a supply voltage range of 2 V to 6 V and utilizes CMOS logic technology from the 74AC series. The device features asynchronous reset functionality and negative-edge triggered clock inputs. It is housed in a 16-SOIC surface-mount package with an operating temperature range of -40°C to +85°C. Propagation delays are specified at 11 ns and 8 ns under standard test conditions.

Counter Dividers Feature Summary

• Integrates a 12-stage binary counter and serial-in parallel-out shift register in a single CMOS IC
• Provides asynchronous reset capability for immediate state initialization
• Supports operation across a wide 2 V to 6 V power supply range
• Delivers high-speed performance with low propagation delay characteristics

Counter Dividers Applications

• Digital frequency division circuits
• Serial-to-parallel data conversion systems
• Timing and counting applications in consumer electronics
• Address generation for memory or I/O devices

Counter Dividers Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm RoHS compliance documentation matches current regulatory requirements. Validate that the SOIC-16 package dimensions align with PCB footprint specifications. Ensure storage conditions prevent moisture damage prior to reflow soldering processes.

Counter Dividers Selection Notes

Select this component when a combined counter and shift register function is required in space-constrained designs. The 74AC series offers faster switching speeds compared to HC equivalents while maintaining compatible pinouts. Consider the 2 V to 6 V operating range for flexibility in varying supply voltages. Evaluate the 12-bit depth against application timing requirements before finalizing the design.

Counter Dividers Part Context

This part belongs to the MC74AC4040 family of 12-stage binary counters. It shares functional compatibility with other 74AC series logic devices, allowing mixed-logic system integration. The DR2G suffix indicates tape-and-reel packaging suitable for automated assembly. It serves as a digital logic building block for sequential circuit implementations requiring binary counting or data shifting capabilities.

Counter Dividers Replacement Considerations

MC74AC4040MELG: Alternative SOEIAJ package variant with identical electrical characteristics. MC74HC4040ADR2G: HC series equivalent offering slower speed but wider temperature range. Verify pinout compatibility and voltage thresholds when substituting with non-AC series components.
