HEF4046BT Nexperia

HEF4046B Phase-locked loop Rev. 5 18 November 2011 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 V power supply range of 3 V to 15 V referenced to V DD SS (usually ground). Unused inputs must be connected to V , V , or another input. DD SS 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.
