SN74HC151N from XBLW SN74HC151N XBLW, in a DIP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I3 | input | Data input 3. One of eight multiplexer data inputs selected by S0-S2 and routed to output Y when enable E is LOW. |
| 2 | I2 | input | Data input 2. One of eight multiplexer data inputs selected by S0-S2 and routed to output Y when enable E is LOW. |
| 3 | I1 | input | Data input 1. One of eight multiplexer data inputs selected by S0-S2 and routed to output Y when enable E is LOW. |
| 4 | I0 | input | Data input 0. One of eight multiplexer data inputs selected by S0-S2 and routed to output Y when enable E is LOW. |
| 5 | Y | output | Multiplexer output. Non-inverting output presenting the value of the selected data input (I0-I7) when E is LOW; forced LOW when E is HIGH. |
| 6 | ~Y | output | Complementary multiplexer output. Inverted version of Y; forced HIGH when E is HIGH. |
| 7 | ~E | input | Active-LOW enable input. When HIGH the multiplexer is disabled (Y=LOW, ~Y=HIGH); when LOW the selected data input is routed to the outputs. |
| 8 | GND | power_in | Ground reference, 0 V. |
| 9 | S2 | input | Common data select input, bit 2 (MSB). With S0/S1 selects which of I0-I7 is routed to the output. |
| 10 | S1 | input | Common data select input, bit 1. With S0/S2 selects which of I0-I7 is routed to the output. |
| 11 | S0 | input | Common data select input, bit 0 (LSB). With S1/S2 selects which of I0-I7 is routed to the output. |
| 12 | I7 | input | Data input 7. One of eight multiplexer data inputs selected by S0-S2 and routed to output Y when enable E is LOW. |
| 13 | I6 | input | Data input 6. One of eight multiplexer data inputs selected by S0-S2 and routed to output Y when enable E is LOW. |
| 14 | I5 | input | Data input 5. One of eight multiplexer data inputs selected by S0-S2 and routed to output Y when enable E is LOW. |
| 15 | I4 | input | Data input 4. One of eight multiplexer data inputs selected by S0-S2 and routed to output Y when enable E is LOW. |
| 16 | VCC | power_in | Positive supply voltage. Recommended operating range 2.0 V to 6.0 V (typical 5.0 V); absolute max +7.0 V. |
