Dual 4-Stage Binary
Ripple Counter with
÷ 2 and ÷ 5 Sections
High–Performance Silicon–Gate CMOS
The MC54/74HC390A 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 4–bit counters, each composed
of a divide–by–two and a divide–by–five section. The divide–by–two and
divide–by–five counters have separate clock inputs, and can be cascaded to
implement various combinations of ÷ 2 and/or ÷ 5 up to a ÷ 100 counter.
Flip–flops internal to the counters are triggered by high–to–low transitions
of the clock input. A separate, asynchronous reset is provided for each 4–bit
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.
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2 to 6 V
Low Input Current: 1 µA
High Noise Immunity Characteristic of CMOS Devices
In Compliance with the Requirements Defined by JEDEC Standard
No 7A
Chip Complexity: 244 FETs or 61 Equivalent Gates
