... 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– ...

... MC54/74HC390 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. CONTROL INPUTS Reset (Pins 2, 14) Asynchronous reset. A high at the Reset input prevents counting, resets the internal flip– ...

... MC54/74HC390 Each half of the MC54/74HC390 has independent 5 sections (except for the Reset function). The counters can be connected to give BCD or bi–quinary (2–5) count sequences. If Output 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 ...
