Dual 4-Stage Binary Ripple Counter W 2, 5 Sections

MC74HC390
Dual 4−Stage Binary
Ripple Counter with
÷ 2 and ÷ 5 Sections
High−Performance Silicon−Gate CMOS
The MC54/74HC390 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
HC390.

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance circuit. For proper operation, Vin and
Vout should be constrained to the
range GND v (Vin or Vout) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.

PIN DESCRIPTIONS
OUTPUTS
QA (Pins 3, 13)
INPUTS
Clock A (Pins 1, 15) and Clock B (Pins 4, 15)
Clock A is the clock input to the ÷ 2 counter; Clock B is
the clock input to the ÷ 5 counter. The internal flip−flops are
toggled by high−to−low transitions of the clock input.
Output of the ÷ 2 counter.
QB, QC, QD (Pins 5, 6, 7, 9, 10, 11)
Outputs of the ÷ 5 counter. QD is the most significant bit.
QA is the least significant bit when the counter is connected
for BCD output as in Figure 4. QB is the least significant bit
when the counter is operating in the bi−quinary mode as in
Figure 5.
CONTROL INPUTS
Reset (Pins 2, 14)
Asynchronous reset. A high at the Reset input prevents
counting, resets the internal flip−flops, and forces QA
through QD low.

APPLICATIONS INFORMATION
Each half of the MC54/74HC390 has independent ÷ 2
and ÷ 5 sections (except for the Reset function). The ÷ 2
and ÷ 5 counters can be connected to give BCD or
bi−quinary (2−5) count sequences. If Output Q A is
connected to the Clock B input (Figure 4), a decade divider
with BCD output is obtained. The function table for the BCD
count sequence is given in Table 1.
To obtain a bi−quinary count sequence, the input signals
connected to the Clock B input, and output QD is connected
to the Clock A input (Figure 5). QA provides a 50% duty
cycle output. The bi−quinary count sequence function table
is given in Table 2.
