CD74HC93M from Texas Instruments, in a SOIC-14. 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 | CP1 | input | Active-low clock input of the divide-by-eight section, with state changes on the HIGH-to-LOW transition; Q0 must be connected externally to it for a 4-bit counter. |
| 2 | MR1 | input | Asynchronous master reset input, gated AND with MR2; when both are high it overrides both clocks and resets all flip-flops (Q0 to Q3 low). |
| 3 | MR2 | input | Asynchronous master reset input, gated AND with MR1; when both are high it overrides both clocks and resets all flip-flops (Q0 to Q3 low). |
| 4 | NC | unconnected | No internal connection. |
| 5 | VCC | power_in | Positive supply voltage, 2 V to 6 V for HC types, with a 0.1-µF bypass capacitor recommended close to the pin. |
| 6 | NC | unconnected | No internal connection. |
| 7 | NC | unconnected | No internal connection. |
| 8 | Q2 | output | Divide-by-four output of the 4-bit ripple counter (third bit), driving up to 10 LSTTL loads for standard outputs. |
| 9 | Q1 | output | Divide-by-two output of the divide-by-eight section (second bit of the 4-bit ripple counter). |
| 10 | GND | power_in | Ground reference (0 V) for the supply. |
| 11 | Q3 | output | Divide-by-eight output of the divide-by-eight section (fourth bit of the 4-bit ripple counter, divide-by-16 overall). |
| 12 | Q0 | output | Output of the divide-by-two section (divide-by-2 from CP0); must be connected externally to CP1 for 4-bit counting. |
| 13 | NC | unconnected | No internal connection. |
| 14 | CP0 | input | Active-low clock input of the divide-by-two section, with state changes on the HIGH-to-LOW transition. |
