CD4522BE

The Texas Instruments CD4522BE is a versatile 4-bit programmable BCD divide-by-N counter from the CD4000 logic family. Designed for flexibility, it supports a wide operating voltage range from 3V to 18V and operates reliably in extreme temperatures from -55°C to 125°C.

This counter features standard CMOS input and push-pull output types, with a count rate of 8 MHz. It supports both positive and negative trigger types and includes an asynchronous reset function. The device is internally synchronous for high internal and external speeds, incrementing on positive clock transitions or negative clock inhibit transitions.

Packaged in a 16-DIP through-hole configuration, the CD4522BE is suitable for various applications including frequency synthesizers, phase-locked loops, programmable down counters, and programmable frequency dividers. Its design includes balanced outputs and a positive input clamp diode for enhanced performance.

Key specifications include a 4-bit count, divide-by-N logic type, and a wide operating temperature range. The maximum input current is rated at 1 µA at 18V over the full package temperature range, and 100 nA at 18V and 25°C. This component meets JEDEC Tentative Standard No. 13B.
