MC14536BDWR2G from onsemi, in a SOIC-16-300mil. 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 | SET | input | A high on Set asynchronously forces Decode Out high and resets the 24 flip-flop stages, and while high it disables the on-chip RC oscillator. |
| 2 | RESET | input | A high on Reset asynchronously forces Decode Out low and resets all 24 flip-flop stages to low, and it also disables the on-chip RC oscillator. |
| 3 | IN1 | input | The internal counters advance on the negative-going edge of this input, which can be an external clock or part of an RC oscillator with OUT1 and OUT2. |
| 4 | OUT1 | output | Buffered output used with IN1 to form an RC oscillator; when an external clock is used it may be left unconnected or drive 1 LSTTL or several CMOS loads. |
| 5 | OUT2 | output | Buffered output used with IN1 to form an RC oscillator; when an external clock is used it may be left unconnected or drive 1 LSTTL or several CMOS loads. |
| 6 | 8-BYPASS | input | A high on this input bypasses the first eight flip-flop stages, leaving a 16-stage counter with all 16 stages selectable by A, B, C and D. |
| 7 | CLOCK INHIBIT | input | A high on this input disconnects the first counter stage from the clocking source, holding the present count while the clocking source may keep running. |
| 8 | VSS | power_in | Ground reference pin; all voltages in the datasheet are referenced to VSS. |
| 9 | A | input | Together with B, C and D, selects the flip-flop stage connected to Decode Out as given in the truth tables. |
| 10 | B | input | Together with A, C and D, selects the flip-flop stage connected to Decode Out as given in the truth tables. |
| 11 | C | input | Together with A, B and D, selects the flip-flop stage connected to Decode Out as given in the truth tables. |
| 12 | D | input | Together with A, B and C, selects the flip-flop stage connected to Decode Out as given in the truth tables. |
| 13 | DECODE OUT | output | Output function depends on configuration; with the monostable disabled it is a 50% duty cycle square wave during free run. |
| 14 | OSC INHIBIT | input | A high level stops the RC oscillator for very low-power standby operation, and it can also be used with an external clock much like Clock Inhibit. |
| 15 | MONO-IN | passive | Timing pin for the on-chip monostable: tying it to VSS disables the monostable, while a resistor to VDD enables it, with the resistor limited to 5 k to 100 k and the external capacitor to a maximum of 1000 pF. |
| 16 | VDD | power_in | Positive supply pin; the device supply range is 3.0 Vdc to 18 Vdc, with a maximum DC supply rating of −0.5 to +18.0 V referenced to VSS. |
