Product Summary

The HEF4520BP is a dual 4-bit internally synchronous binary counter. The counter has an active HIGH clock input (nCP0) and an active LOW clock input (nCP1), buffered outputs from all four bit positions (nQ0 to nQ3) and an active HIGH overriding asynchronous master reset input (nMR). The HEF4520BP advances on either the LOW-to-HIGH transition of the nCP0 input if nCP1 is HIGH or the HIGH-to-LOW transition of the nCP1 input if nCP0 is low. The HEF4520BP 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 also suitable for use over the full industrial (-40℃ to +85℃) temperature range.

Parametrics

HEF4520BP absolute maximum ratings: (1)supply voltage:-0.5V to +18V; (2)input clamping current:±10mA; (3)input voltage:-0.5V to VDD+0.5V; (4)output clamping current:±10mA; (5)input/output current:±10mA; (6)supply current:50mA; (7)storage temperature per output:-65℃ to +150℃; (8)ambient temperature:-40℃ to +85℃; (9)total power dissipation:750mW; (10)power dissipation:100mW.
