CD54HC4046AF3A

The CD54HC4046AF3A is a High Speed CMOS Logic device featuring a Phase-Locked-Loop (PLL) with a Voltage-Controlled Oscillator (VCO). Manufactured by Texas Instruments, this IC is designed for applications requiring frequency synthesis, modulation, and synchronization.

Key electrical characteristics include a wide operating supply voltage range, with the VCO section supporting 3V to 6V and the digital section operating from 2V to 6V. The device offers an operating frequency range up to 18MHz typically at 5V, with a minimum center frequency of 12MHz at 4.5V. It provides standard and bus driver outputs with fanout capabilities of 10 and 15 LSTTL loads, respectively. High noise immunity is ensured with NIL and NIH ratings of 30% of VCC at 5V.

This component is housed in a CDIP (J) package with an area of 135.3552 mm². It is rated for military applications and operates across a broad temperature range of -55°C to 125°C. The design includes features like VCO-inhibit control for ON/OFF keying and low standby power, along with excellent VCO frequency linearity and minimal frequency drift.

Applications for the CD54HC4046AF3A include FM modulation and demodulation, frequency synthesis and multiplication, frequency discrimination, tone decoding, data synchronization and conditioning, and motor-speed control. Its balanced propagation delay and transition times, combined with significant power reduction compared to LSTTL logic, make it a versatile choice for various electronic designs.
