MC14046BFEL

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC14046BFEL is a Phase Locked Loop (PLL) integrated circuit manufactured by onsemi, housed in a 16-pin SOIC-16 Wide Body surface-mount package. It integrates two phase comparators, a voltage-controlled oscillator (VCO), a source follower, and a zener diode. The device operates within a supply voltage range of 3.0 V to 18.0 V and supports an operating temperature range from -55°C to +125°C. It features buffered outputs compatible with Low-Power TTL logic levels and includes diode protection on all inputs.
