Overview
The CD4046BNSR is a CMOS Micropower Phase-Locked Loop (PLL) produced by Texas Instruments. This device is part of the CD4046B family and is supplied in a 16-lead small-outline package (NSR suffix). The CD4046B PLL consists of a low-power, linear voltage-controlled oscillator (VCO) and two different phase comparators, along with a common signal-input amplifier and a common comparator input. It also includes a 5.2-V zener diode for supply regulation if necessary. Despite being discontinued by Texas Instruments, the CD4046B remains a versatile component for various analog and digital applications.
