Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | Address input bit 0. Binary-weighted select input; combined with A1 and A2 selects one of eight outputs Y0-Y7. CMOS input, VIH ≥ 0.7·VCC, VIL ≤ 0.2·VCC. |
| 2 | A1 | input | Address input bit 1. Binary-weighted select input; combined with A0 and A2 selects one of eight outputs Y0-Y7. CMOS input, VIH ≥ 0.7·VCC, VIL ≤ 0.2·VCC. |
| 3 | A2 | input | Address input bit 2 (MSB). Binary-weighted select input; combined with A0 and A1 selects one of eight outputs Y0-Y7. CMOS input, VIH ≥ 0.7·VCC, VIL ≤ 0.2·VCC. |
| 4 | E1 | input | Enable input 1, active LOW. All outputs Y0-Y7 are LOW unless E1 = LOW, E2 = LOW, and E3 = HIGH. |
| 5 | E2 | input | Enable input 2, active LOW. All outputs Y0-Y7 are LOW unless E1 = LOW, E2 = LOW, and E3 = HIGH. |
| 6 | E3 | input | Enable input 3, active HIGH. All outputs Y0-Y7 are LOW unless E1 = LOW, E2 = LOW, and E3 = HIGH. |
| 7 | Y7 | output | Decoded output 7 (A2=1, A1=1, A0=1). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V. |
| 8 | GND | power_in | Ground reference (0 V). Connect to system ground. |
| 9 | Y6 | output | Decoded output 6 (A2=1, A1=1, A0=0). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V. |
| 10 | Y5 | output | Decoded output 5 (A2=1, A1=0, A0=1). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V. |
| 11 | Y4 | output | Decoded output 4 (A2=1, A1=0, A0=0). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V. |
| 12 | Y3 | output | Decoded output 3 (A2=0, A1=1, A0=1). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V. |
| 13 | Y2 | output | Decoded output 2 (A2=0, A1=1, A0=0). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V. |
| 14 | Y1 | output | Decoded output 1 (A2=0, A1=0, A0=1). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V. |
| 15 | Y0 | output | Decoded output 0 (A2=0, A1=0, A0=0). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V. |
| 16 | VCC | power_in | Positive supply voltage, 2 V to 6 V (recommended). Decouple with 0.1 µF ceramic capacitor to GND placed close to the pin. |
