Product data sheet
1. General description
The HEF4046B is a phase-locked loop circuit that consists of a linear Voltage Controlled Oscillator (VCO) and two different phase comparators with a common signal input amplifier and a common comparator input. A 7 V
regulator (Zener) diode is provided for supply voltage regulation if necessary. For a functional description see Section 6.
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.
2. Features and benefits
Fully static operation 5 V, 10 V, and 15 V parametric ratings Standardized symmetrical output characteristics Specified from 40 C to +85 C Complies with JEDEC standard JESD 13-B
3. Ordering information
Table 1. Ordering information All types operate from 40 C to +85 C.
