You're currently on: Catalog » DIY Kits, Electronics and ICs » 4046 – phase-locked loop (PLL) with VCO, CMOS 4000B, DIP-16 (generic)
The 4046 is a 4000B-series CMOS IC containing a voltage-controlled oscillator (VCO), two phase comparators (an XOR type and an edge-triggered type), a source-follower output and a built-in zener diode. It is used for frequency synthesis, FM demodulation, frequency multiplication, tone decoding and as a simple VCO. Like most 4000-series parts it works over a wide supply range; check the limits in the datasheet for the specific manufacturer and series. It comes in a 16-pin plastic DIP.
Condition: mixed surplus lot, untested. The bag may contain used (pulled) ICs of the same type from different manufacturers, so marking and date code vary. The photo shows one chip from this lot (Motorola MC14046BCP ZZZ8624); only the background was cleaned to white, preserving the marking and leads.
Minimum order: 1 pc.
