CD74HCT7046AM Description

Short technical summary and product information.

The CD74HCT7046AM from Texas Instruments is a high-speed CMOS logic Phase-Locked Loop (PLL) IC featuring a Voltage-Controlled Oscillator (VCO) and Lock Detector. This component is designed for applications requiring precise frequency control and synchronization.

 

Key electrical specifications include an operating voltage range of 4.5V to 5.5V for HCT types, with VCO section operating from 3V to 6V and digital section from 2V to 6V. It supports a frequency of 38MHz and offers fanout capabilities of 10 LSTTL loads for standard outputs and 15 LSTTL loads for bus driver outputs. The operating temperature range is wide, spanning from -55°C to 125°C.

 

This PLL IC is suitable for various applications such as FM modulation and demodulation, frequency synthesis and multiplication, frequency discrimination, tone decoding, data synchronization, voltage-to-frequency conversion, and motor-speed control. Its design emphasizes balanced propagation delay and transition times, offering significant power reduction compared to LSTTL logic.

 

The CD74HCT7046AM is available in a 16-SOIC package, designed for surface mounting. The package dimensions are 16-SOIC (0.154", 3.90mm Width).
