Overview
The CD4017BPWR is a 5-stage Johnson counter integrated circuit produced by Texas Instruments. It is part of the CMOS 4000 series and is commonly referred to as a decade counter/divider. This IC features 10 decoded outputs and is designed for various counting, dividing, and sequencing applications in electronic circuits.
The CD4017BPWR operates with a fully static design, meaning it does not rely on dynamic clock signals, and it supports medium-speed operation with a typical frequency of 10 MHz at a supply voltage of 10 V. The IC includes inputs for CLOCK, RESET, and CLOCK INHIBIT signals, with Schmitt trigger action in the CLOCK input circuit for pulse shaping.
