TC4521BP 24-Stage Frequency Divider
TC4521BP
TC4521BP is frequency divider consisting of 24 stages of
flip-flop. The input section is equipped with an inverter to enable
to use either RC oscillator circuit or crystal oscillator circuit and
to accept pulse from external clock source.
Each flip-flop is inverted by the falling edge of the output of
previous stage flip-flop and this can count up to the maximum of
2²⁴ = 16,777,216.
Since six outputs, 2¹⁸, 2¹⁹, 2²⁰, 2²¹, 2²², and 2²³ are available
besides of 2²⁴, adjustment of frequency divided output can be
achieved.
