MC74HC390A Dual 4-Stage Binary Ripple Counter with ÷ 2 and ÷ 5 Sections High−Performance Silicon−Gate CMOS http://onsemi.com 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 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.

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. _C 260 Stresses exceeding those listed in the Maximum Ratings table may damage the device.

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 5. QB is the least significant bit when the counter is operating in the bi−quinary mode as in Figure 6. 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.

The ÷ 2 and ÷ 5 counters can be connected to give BCD or bi−quinary (2−5) count sequences. If Output QA 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 6). QA provides a 50% duty cycle output.
