DESCRIPTION

TheHCC/HCF4541B Programmable Timer is com-

posed of a 16-stage binary counter, an oscillator

controlled by2 external resistorsand a capacitor, 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 of the stagedepends on the time-

select inputs A or B (see frequency selection table).

The output is available in one 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, with a frequency equal to theoscillator

frequency divided by 2^N. When this MODE input is
