CD74HC390E

lingxingic · Counters, Dividers · DIP-16

CD74HC390E from lingxingic, in a DIP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 0CP1 input Clock input of the divide-by-2 section, triggered on the HIGH-to-LOW edge.
2 1MR input Asynchronous master reset input, active HIGH; a HIGH overrides the clocks and sets the outputs LOW.
3 1Q0 output Flip-flop output nQ0; in BCD decade operation it is connected to the nCP1 input of the divide-by-5 section.
4 1CP1 input Clock input of the divide-by-5 section, triggered on the HIGH-to-LOW edge.
5 1Q1 output Flip-flop output nQ1 of the counter section.
6 1Q2 output Flip-flop output nQ2 of the counter section.
7 1Q3 output Flip-flop output nQ3 of the counter section; in bi-quinary operation it is connected to the nCP0 input.
8 GND power_in Ground reference (0 V) for all voltages.
9 2Q3 output Flip-flop output nQ3 of the second counter section; in bi-quinary operation it is connected to the nCP0 input.
10 2Q2 output Flip-flop output nQ2 of the second counter section.
11 2Q1 output Flip-flop output nQ1 of the second counter section.
12 1CP2 input Clock input of the divide-by-5 section (second counter), triggered on the HIGH-to-LOW edge.
13 2Q0 output Flip-flop output nQ0 of the second counter section; in BCD decade operation it is connected to the nCP1 input of its divide-by-5 section.
14 2MR input Asynchronous master reset input, active HIGH; a HIGH overrides the clocks and sets the outputs LOW.
15 0CP2 input Clock input of the divide-by-2 section (second counter), triggered on the HIGH-to-LOW edge.
16 VCC power_in Supply voltage; recommended range 2.0 V to 6.0 V, absolute maximum 7.0 V.
