CD4518BCN – TEXAS INSTRUMENTS

Overview

The Texas Instruments CD4518BCN is a dual, BCD (Binary Coded Decimal) up-counter integrated circuit designed for digital counting applications. Its primary function is to increment a BCD count upon detecting a rising clock edge, with independent control over each of its two counters. A critical design consideration for this CMOS device is its susceptibility to static discharge and potential for latch-up in high-voltage transient conditions, necessitating careful PCB layout and handling procedures to ensure long-term operational integrity, especially in noise-sensitive environments.

Key Features
