CD40103BDR

lingxingic · Counters, Dividers · SOP-16

CD40103BDR 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 CP input Clock input; the counter decrements on each LOW-to-HIGH (positive-going) clock transition.
2 MR input Asynchronous master reset input, active LOW; when LOW it clears the counter to its maximum count (decimal 255) regardless of the other inputs.
3 TE input Terminal enable input, active LOW; counting is inhibited while this input is HIGH.
4 P0 input Jam input 0 (least significant bit of the 8-bit preset word), loaded into the counter when PE or PL is LOW.
5 P1 input Jam input 1 of the 8-bit preset word, loaded into the counter when PE or PL is LOW.
6 P2 input Jam input 2 of the 8-bit preset word, loaded into the counter when PE or PL is LOW.
7 P3 input Jam input 3 of the 8-bit preset word, loaded into the counter when PE or PL is LOW.
8 GND power_in Ground (0 V) reference for all voltages.
9 PL input Asynchronous preset enable input, active LOW; when LOW, data at P0 to P7 is forced asynchronously into the counter regardless of the state of PE, TE or CP.
10 P4 input Jam input 4 of the 8-bit preset word, loaded into the counter when PE or PL is LOW.
11 P5 input Jam input 5 of the 8-bit preset word, loaded into the counter when PE or PL is LOW.
12 P6 input Jam input 6 of the 8-bit preset word, loaded into the counter when PE or PL is LOW.
13 P7 input Jam input 7 (most significant bit of the 8-bit preset word), loaded into the counter when PE or PL is LOW.
14 TC output Terminal count output, active LOW; goes LOW when the count reaches zero (if TE is LOW) and remains LOW for one full clock period.
15 PE input Synchronous preset enable input, active LOW; data at P0 to P7 is clocked into the counter on the next LOW-to-HIGH CP transition regardless of TE.
16 VCC power_in Positive supply voltage; recommended operating range is 2.0 V to 6.0 V referenced to GND.
