CD74HCT4046AM

Product Overview

The CD74HCT4046AM from Harris Corporation is a surface-mount phase-locked loop integrated circuit housed in a 16-SOIC package with a 3.90 mm body width. It provides a single PLL circuit with CMOS input and CMOS output, operating from a 4.5 V to 5.5 V supply. The device supports a maximum frequency of 38 MHz and operates over a temperature range of -55°C to 125°C. Its input-to-output ratio is 1:4, and the differential input/output configuration is non-differential. This part is suited to timing and frequency comparison functions within 4.5 V to 5.5 V CMOS logic systems.

Applications

• Clock and timing circuits that use a single phase-locked loop with CMOS input and output
• Frequency tracking functions in 4.5 V to 5.5 V CMOS logic systems
• Frequency locking circuits operating at frequencies up to 38 MHz
• Phase synchronization in CMOS logic systems operating within the specified supply and temperature limits

Design & Procurement Notes

When selecting the CD74HCT4046AM, confirm that the system supply remains within 4.5 V to 5.5 V and that the target frequency does not exceed 38 MHz. The CMOS input and output levels should match the surrounding logic interface, while the 1:4 input-to-output ratio and non-differential configuration should be reflected in the timing architecture. Because the package is a surface-mount 16-SOIC with 3.90 mm width, PCB land patterns and thermal clearance should be planned for the -55°C to 125°C operating range. For procurement documentation, retain the exact Harris Corporation part number CD74HCT4046AM and the 16-SOIC package designation.
