Phase−Locked Loop

High−Performance Silicon−Gate CMOS

The MC74HC4046A is similar in function to the MC14046 Metal gate CMOS device. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

Features

• Output Drive Capability: 10 LSTTL Loads

• Low Power Consumption Characteristic of CMOS Devices

• Operating Speeds Similar to LSTTL

• Wide Operating Voltage Range: 3.0 to 6.0 V

• Low Input Current: 1.0 μA Maximum (except SIGIN and COMPIN)

• In Compliance with the Requirements Defined by JEDEC Standard No. 7A

• Low Quiescent Current: 80 μA Maximum (VCO disabled)

• High Noise Immunity Characteristic of CMOS Devices

• Diode Protection on all Inputs

• Chip Complexity: 279 FETs or 70 Equivalent Gates
