CD74HCT4046AE Description

Short technical summary and product information.

The CD74HCT4046AE from HAR is a High Speed CMOS Logic integrated circuit featuring a Phase-Locked-Loop with Voltage-Controlled Oscillator (VCO). This device is designed for applications requiring frequency modulation and demodulation, frequency synthesis, and data synchronization.

It offers a wide operating temperature range from -55°C to 125°C, making it suitable for demanding environments. The digital section operates from 2V to 6V, while the VCO section supports a range of 3V to 6V. The device provides a typical operating frequency range of up to 18MHz at 5V, with a minimum center frequency of 12MHz at 4.5V.

Available in SOIC and PDIP packages, the CD74HCT4046AE offers standard output fanout of 10 LSTTL loads and bus driver output fanout of 15 LSTTL loads. Its HCT technology ensures direct LSTTL input logic compatibility and CMOS input compatibility.

Key features include excellent VCO frequency linearity, VCO-inhibit control for ON/OFF keying and low standby power, and minimal frequency drift. Applications include FM modulation/demodulation, frequency synthesis and multiplication, tone decoding, and voltage-to-frequency conversion.
