CD40103BE 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 | CP | input | Clock input, edge-triggered on the LOW-to-HIGH transition; the counter decrements on each positive-going CP transition. |
| 2 | MR | input | Asynchronous master reset, active LOW; when LOW it clears the counter to its maximum count (decimal 255) regardless of the other inputs. |
| 3 | TE | input | Terminal enable, active LOW; counting is inhibited while TE is HIGH, and TC goes LOW at zero count only when TE is LOW. |
| 4 | P0 | input | Jam input 0, least significant bit of the 8-bit preset word P0 to P7; inputs include clamp diodes so current-limiting resistors can be used for voltages above VCC. |
| 5 | P1 | input | Jam input 1, bit 1 of the 8-bit preset word P0 to P7; inputs include clamp diodes so current-limiting resistors can be used for voltages above VCC. |
| 6 | P2 | input | Jam input 2, bit 2 of the 8-bit preset word P0 to P7; inputs include clamp diodes so current-limiting resistors can be used for voltages above VCC. |
| 7 | P3 | input | Jam input 3, bit 3 of the 8-bit preset word P0 to P7; inputs include clamp diodes so current-limiting resistors can be used for voltages above VCC. |
| 8 | GND | power_in | Ground (0 V) reference for all voltages. |
| 9 | PL | input | Asynchronous preset enable, active LOW; when LOW, the jam data P0 to P7 is asynchronously forced into the counter regardless of PE, TE or CP. |
| 10 | P4 | input | Jam input 4, bit 4 of the 8-bit preset word P0 to P7; inputs include clamp diodes so current-limiting resistors can be used for voltages above VCC. |
| 11 | P5 | input | Jam input 5, bit 5 of the 8-bit preset word P0 to P7; inputs include clamp diodes so current-limiting resistors can be used for voltages above VCC. |
| 12 | P6 | input | Jam input 6, bit 6 of the 8-bit preset word P0 to P7; inputs include clamp diodes so current-limiting resistors can be used for voltages above VCC. |
| 13 | P7 | input | Jam input 7, most significant bit of the 8-bit preset word P0 to P7; inputs include clamp diodes so current-limiting resistors can be used for voltages above VCC. |
| 14 | TC | output | Terminal count output, active LOW; goes LOW when the count reaches zero (if TE is LOW) and stays LOW for one full clock period, and is used for cascading. |
| 15 | PE | input | Synchronous preset enable, active LOW; when LOW, the jam data is clocked into the counter on the next LOW-to-HIGH CP transition. |
| 16 | VCC | power_in | Positive supply voltage; recommended supply range is 2.0 V to 6.0 V with respect to GND. |
