MC74HC390A
Dual 4Stage Binary Ripple
Counter with
÷
2 and
÷
5
Sections
HighPerformance SiliconGate CMOS
The MC74HC390A is identical in pinout to the LS390. The device
inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LSTTL outputs.
This device consists of two independent 4bit counters, each
composed of a dividebytwo and a dividebyfive section. The
dividebytwo and dividebyfive counters have separate clock
inputs, and can be cascaded to implement various combinations of
÷
2
and/or
÷
5 up to a
÷
100 counter.
Flipflops internal to the counters are triggered by hightolow
transitions of the clock input. A separate, asynchronous reset is
provided for each 4bit counter. State changes of the Q outputs do not
occur simultaneously because of internal ripple delays. Therefore,
decoded output signals are subject to decoding spikes and should not
be used as clocks or strobes except when gated with the Clock of the
HC390A.
