DESCRIPTION
The
HCC/HCF4541B
Programmable Timeriscom-
posed of a 16-stage binary counter, an oscillator
controlled by2 external resistorsandacapacitor, an
output control logic and an automatic power-on
reset circuit. The counter varies on positive-edge
clock transation and it can be cleared by the MAS-
TER RESET input. The output from this timer is the
Q or Q output from the 8th, 13th, or 16th counter
stage.The choice ofthe stagedepends onthetime-
selectinputs Aor B(see frequency selection table).
The output is available inone of the two modes that
can be selected via the MODE input, pin 10 (see
truth table). The output turns out as a continuous
squarewave,withafrequencyequal totheoscillator
frequency divided by 2
