CD74HCT4040M

Counter Dividers Overview

The CD74HCT4040M is a 12-bit asynchronous binary counter manufactured by Texas Instruments, utilizing HCT CMOS logic technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum counting rate of 25 MHz. The device features negative-edge triggering for its internal flip-flops and provides an asynchronous reset function. Designed for surface-mount applications, it is housed in a 16-SOIC package with a width of 0.154 inches (3.90 mm). The component is rated for operation across an extended temperature range from -55°C to +125°C.

Counter Dividers Feature Summary

• Integrates twelve cascaded D-type flip-flops configured as a single 12-bit asynchronous binary counter.

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting sequences in control systems
• Timing and delay generation modules

Counter Dividers Procurement Notes

Verify the manufacturer designation on the datasheet, as the CD74HCT4040M is primarily produced by Texas Instruments. Confirm that the specific orderable part number matches the required SOIC-16 package and HCT logic family specifications. Ensure compliance with RoHS3 standards if environmental regulations apply to the target assembly process.

Counter Dividers Selection Notes

Select this component when a 12-bit asynchronous count sequence is required with TTL-compatible input levels provided by the HCT series. The 25 MHz maximum frequency rating suits moderate-speed digital timing applications. Verify that the 16-SOIC footprint aligns with the PCB layout constraints and that the operating temperature range meets the environmental requirements of the final system.

Counter Dividers Part Context

This device belongs to the CD74HCT4040 family of high-speed CMOS logic counters. It serves as a fundamental building block for sequential logic designs requiring binary accumulation or frequency division. The HCT variant ensures compatibility with standard TTL logic families while maintaining the low power consumption characteristics inherent to CMOS technology.
