TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC4521BP

Transcription

1 TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic 24-Stage Frequency Divider is frequency divider coisting 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 2 24 = 16,777,216. Since six outputs, 2 18, 2 19, 2 20, 2 21, 2 22, and 2 23 are available besides of 2 24, adjustment of frequency divided output can be achieved. Weight: 1.00 g (typ.)
