74HCT4046AD Description

Short technical summary and product information.

The 74HCT4046AD from NXP Semiconductors is a high-speed Si-gate CMOS device designed for phase-locked loop applications with an integrated Voltage Controlled Oscillator (VCO). It operates across a wide supply voltage range, with the VCO section supporting 3.0 V to 6.0 V and the digital section supporting 2.0 V to 6.0 V.

Key features include low power consumption and a VCO-Inhibit control for ON/OFF keying and low standby power. The device offers a typical center frequency of up to 17 MHz at 4.5 V. It provides a choice of three phase comparators: EXCLUSIVE-OR, edge-triggered J-K flip-flop, and edge-triggered RS flip-flop. The VCO exhibits excellent linearity and low frequency drift with supply voltage and temperature variations.

This device is available in an SO16 package and is suitable for surface mount applications. It also features robust ESD protection, exceeding 2 kV for HBM Class 2 and 1 kV for CDM Class C3.

Applications for the 74HCT4046AD include FM modulation and demodulation, frequency synthesis and multiplication, frequency discrimination, tone decoding, data synchronization and conditioning, voltage-to-frequency conversion, and motor-speed control.
