CD4046AF/3

Overview

The CD4046AF/3 is a Phase Locked Loop (PLL) integrated circuit manufactured by Harris Corporation. It utilizes CMOS technology and is housed in a 16-lead Ceramic Dual-In-Line Package (CDIP). The device operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55°C to +125°C, suitable for military-grade environments.

Feature Summary

• Integrates two distinct phase detectors: an exclusive OR gate type with triangular characteristics and a digital edge-triggered type.

Applications

• Frequency synthesis systems requiring stable reference generation.
• Motor speed control loops utilizing the internal voltage-controlled oscillator.

Procurement Notes

Verify the specific suffix 'F3A' confirms the hermetic ceramic package construction required for the application environment. Confirm RoHS compliance status as the component may not meet current environmental directives. Validate that the manufacturer designation aligns with Harris Corporation specifications rather than subsequent licensees.

Selection Notes

Select this component when a wide supply voltage range up to 18 V is necessary compared to standard 5 V logic families. Ensure the design accommodates the 16-pin ceramic DIP footprint and thermal requirements associated with military-grade temperature ratings.

Part Context

This part belongs to the CD4046 family of PLL circuits. The 'F3A' suffix specifically denotes the 16-lead hermetic ceramic dual-in-line package variant produced by Harris Corporation, distinguishing it from plastic or small-outline package versions found in commercial series.
