CD4026BM

lingxingic · Counters, Dividers · SOP-16

CD4026BM from lingxingic, in a SOP-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 CLK input Clock input; the function table shows the counter advancing on the rising edge of CLK when CLKN is LOW.
2 CLKN input Clock inhibit input; the function table shows it must be LOW for the counter to advance, and it is used with CLK for the falling-edge count.
3 DIS_EI input Display enable input; when LOW the decoded outputs are blanked (all segment outputs go LOW), per the function table.
4 DIS_EO output Display enable output, which goes LOW for the decade state that blanks the display, per the function table.
5 CARRY output Carry output that pulses to indicate the counter has reached the carry state, used to clock the next stage.
6 F output Segment output F of the decoded 7-segment display.
7 G output Segment output G of the decoded 7-segment display.
8 VSS power_in Ground supply voltage; all voltages are referenced to VSS (0 V).
9 D output Segment output D of the decoded 7-segment display.
10 A output Segment output A of the decoded 7-segment display.
11 E output Segment output E of the decoded 7-segment display.
12 B output Segment output B of the decoded 7-segment display.
13 C output Segment output C of the decoded 7-segment display.
14 UCS output Ungated C segment output, the C segment driven without display blanking, per the function table.
15 RST input Reset input; the function table shows the counter returns to 0 when RST is HIGH.
16 VDD power_in Supply voltage; the recommended operating range is 3 V to 15 V.
