MC74HC4040ANG

Counter Dividers Overview

The MC74HC4040ANG is a 12-stage binary ripple counter manufactured by onsemi in the 74HC series. It operates within a supply voltage range of 2.0 V to 6.0 V and supports a maximum clock frequency of 50 MHz at 6.0 V. The device features asynchronous active-high reset, negative-edge triggered clocking, and outputs directly interfacing with CMOS, NMOS, and TTL logic families. Packaged in a 16-lead PDIP (N Suffix), it functions as a high-performance silicon-gate CMOS component.

Counter Dividers Feature Summary

• Consists of 12 master-slave flip-flops where each output divides the preceding frequency by two
• State counter advances on the negative-going edge of the Clock input
• Asynchronous active-high Reset forces all Q outputs low immediately
• Outputs provide drive capability for 10 LSTTL loads

Counter Dividers Applications

• Time-base generator circuits requiring precise frequency division
• Digital counting applications utilizing binary state progression
• Frequency divider stages in signal processing systems

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'N' corresponds to the 16-lead Plastic Dual In-line Package (PDIP) before procurement. Confirm that the 'G' suffix indicates a lead-free package compliant with RoHS standards. Ensure the selected variant matches the required shipping quantity, such as 2000 units per box for this specific package type.

Counter Dividers Selection Notes

Select this component when a 12-bit binary ripple counter is required within the 74HC logic family specifications. Consider the internal ripple delays which cause non-simultaneous state changes; decoded signals may require gating with the Clock for designs sensitive to decoding spikes. Verify compatibility with the target system's voltage levels and noise immunity requirements.

Counter Dividers Part Context

This part belongs to the MC74HC4040A product line, which is identical in pinout to the standard CMOS MC14040. The device inputs are compatible with standard CMOS outputs and can interface with LSTTL outputs using pullup resistors. It represents a high-performance silicon-gate CMOS implementation designed for general-purpose digital counting tasks.

Counter Dividers Replacement Considerations

Public confirmed substitute part numbers include CD74HC4040E and SN74HC4040N from Texas Instruments.
