General description
The HEF4520B 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 counter 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. Either nCP0 or
nCP1 may be used as the clock input to the counter while the other clock input may be
used as a clock enable input. Schmitt trigger action makes the clock input highly tolerant
of slower clock rise and fall times. A HIGH on nMR resets the counter (nQ0 to
nQ3 = LOW) independent of nCP0 and nCP1.
It operates over a recommended V
DD
power supply range of 3 V to 15 V referenced to V
SS
(usually ground). Unused inputs must be connected to V
DD
, V
SS
, or another input. It is
also suitable for use over the full industrial (
40

C to +85
°
C) temperature range.
