Product Summary

The HEF4526BT is a synchronous programmable 4-bit binary down counter with active HIGH and active LOW clock inputs (CP0, CP1), an asynchronous parallel load input (PL), four parallel inputs (A0 to A3), a cascade feedback input (CF), four buffered parallel outputs (Q0 to Q3), a terminal count output (TC), an overriding asynchronous master reset input (MR) and a decoded TC output that can be used for divide-by-n applications. The HEF4526BT operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS(usually ground). Unused inputs must be connected to VDD, VSS, or another input. It is suitable for use over the full industrial (-40℃ to +85℃) temperature range. The applications of the HEF4526BT are Divide-by-n counter, Programmable frequency divider.
