CD74HCT4046AE Description

Short technical summary and product information.

The CD74HCT4046AE from Texas Instruments is a High Speed CMOS Logic Phase-Locked-Loop (PLL) with Voltage-Controlled Oscillator (VCO). This IC is designed for applications requiring precise frequency control and synthesis.

 

Key electrical specifications include a typical operating frequency range up to 18MHz at 5V, with a minimum center frequency of 12MHz at 4.5V. The VCO section operates from 3V to 6V, while the digital section operates from 2V to 6V. It supports direct LSTTL input logic compatibility for HCT types.

 

This device features a choice of three phase comparators, excellent VCO frequency linearity, and a VCO-inhibit control for ON/OFF keying and low standby power. It is suitable for applications such as FM modulation and demodulation, frequency synthesis, tone decoding, and voltage-to-frequency conversion.

 

The CD74HCT4046AE is available in a 16-PDIP package and is designed for through-hole mounting. It operates over a wide temperature range of -55°C to 125°C.
