HEF4516BT,653

Counter Dividers Overview

The HEF4516BT,653 is a CMOS binary up/down counter in a 16-lead SO plastic small outline package (SOT109-1). It features an edge-triggered synchronous architecture with four parallel inputs and outputs. The device operates on a recommended supply voltage range of 3 V to 15 V referenced to ground. It includes dedicated control pins for clock input, count enable, and direction selection. An asynchronous master reset input allows immediate clearing of the internal state.
