Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1A | input | Channel 1 Schmitt-trigger inverter input; accepts 0V to VCC with hysteresis ΔVT (min 0.2V at 2V, typical 0.6V at 2V supply) |
| 2 | 1Y | output | Channel 1 inverted output (Y = NOT A) with balanced CMOS push-pull output; sources/sinks continuous up to ±25 mA |
| 3 | 2A | input | Channel 2 Schmitt-trigger inverter input; accepts 0V to VCC with hysteresis ΔVT (min 0.2V at 2V, typical 0.6V at 2V supply) |
| 4 | 2Y | output | Channel 2 inverted output (Y = NOT A) with balanced CMOS push-pull output; sources/sinks continuous up to ±25 mA |
| 5 | 3A | input | Channel 3 Schmitt-trigger inverter input; accepts 0V to VCC with hysteresis ΔVT (min 0.2V at 2V, typical 0.6V at 2V supply) |
| 6 | 3Y | output | Channel 3 inverted output (Y = NOT A) with balanced CMOS push-pull output; sources/sinks continuous up to ±25 mA |
| 7 | GND | power_in | Ground; 0V reference and maximum output sink current terminal for all output stages |
| 8 | 4Y | output | Channel 4 inverted output (Y = NOT A) with balanced CMOS push-pull output; sources/sinks continuous up to ±25 mA |
| 9 | 4A | input | Channel 4 Schmitt-trigger inverter input; accepts 0V to VCC with hysteresis ΔVT (min 0.2V at 2V, typical 0.6V at 2V supply) |
| 10 | 5Y | output | Channel 5 inverted output (Y = NOT A) with balanced CMOS push-pull output; sources/sinks continuous up to ±25 mA |
| 11 | 5A | input | Channel 5 Schmitt-trigger inverter input; accepts 0V to VCC with hysteresis ΔVT (min 0.2V at 2V, typical 0.6V at 2V supply) |
| 12 | 6Y | output | Channel 6 inverted output (Y = NOT A) with balanced CMOS push-pull output; sources/sinks continuous up to ±25 mA |
| 13 | 6A | input | Channel 6 Schmitt-trigger inverter input; accepts 0V to VCC with hysteresis ΔVT (min 0.2V at 2V, typical 0.6V at 2V supply) |
| 14 | VCC | power_in | Positive power supply voltage; operating range 2V minimum to 6V maximum with 5V nominal (source current limit ±50 mA continuous through VCC) |
