CD74HC4046AM Description

Short technical summary and product information.

The CD74HC4046AM from Texas Instruments is a high-speed silicon-gate CMOS Phase-Locked-Loop (PLL) circuit featuring a linear Voltage-Controlled Oscillator (VCO). It is pin-compatible with the CD4046B series and offers excellent VCO frequency linearity.

 

This PLL IC supports a wide operating supply voltage range from 3V to 6V for the VCO section and 2V to 6V for the digital section. It operates across a temperature range of -55°C to 125°C. The device provides three phase comparators: EXCLUSIVE-OR, Edge-Triggered JK Flip-Flop, and Edge-Triggered RS Flip-Flop. Standard outputs offer a fanout of 10 LSTTL loads, while bus driver outputs support 15 LSTTL loads.

 

The CD74HC4046AM is suitable for applications such as FM modulation and demodulation, frequency synthesis and multiplication, frequency discrimination, tone decoding, data synchronization and conditioning, voltage-to-frequency conversion, and motor-speed control. It is supplied in a 16-SOIC surface mount package.

 

Key electrical characteristics include an operating frequency range up to 18MHz typically at 5V, with a minimum center frequency of 12MHz at 4.5V. The input and output interfaces are CMOS compatible.
