Asserts LOW when address inputs A3:A0 = 0000 and both enables are LOW; HIGH otherwise. |+| 2 | Y1 | output | Decoded active-LOW output 1. Asserts LOW when A3:A0 = 0001 and both enables are LOW. |+| 3 | Y2 | output | Decoded active-LOW output 2. Asserts LOW when A3:A0 = 0010 and both enables are LOW. |+| 4 | Y3 | output | Decoded active-LOW output 3. Asserts LOW when A3:A0 = 0011 and both enables are LOW. |+| 5 | Y4 | output | Decoded active-LOW output 4. Asserts LOW when A3:A0 = 0100 and both enables are LOW. |+| 6 | Y5 | output | Decoded active-LOW output 5. Asserts LOW when A3:A0 = 0101 and both enables are LOW. |+| 7 | Y6 | output | Decoded active-LOW output 6. Asserts LOW when A3:A0 = 0110 and both enables are LOW. |+| 8 | Y7 | output | Decoded active-LOW output 7. Asserts LOW when A3:A0 = 0111 and both enables are LOW. |+| 9 | Y8 | output | Decoded active-LOW output 8. Asserts LOW when A3:A0 = 1000 and both enables are LOW. |+| 10 | Y9 | output | Decoded active-LOW output 9. Asserts LOW when A3:A0 = 1001 and both enables are LOW. |+| 11 | Y10 | output | Decoded active-LOW output 10. Asserts LOW when A3:A0 = 1010 and both enables are LOW. |+| 12 | GND | power_in | Ground reference (0 V). Supply return for all internal logic. |+| 13 | Y11 | output | Decoded active-LOW output 11. Asserts LOW when A3:A0 = 1011 and both enables are LOW. |+| 14 | Y12 | output | Decoded active-LOW output 12. Asserts LOW when A3:A0 = 1100 and both enables are LOW. |+| 15 | Y13 | output | Decoded active-LOW output 13. Asserts LOW when A3:A0 = 1101 and both enables are LOW. |+| 16 | Y14 | output | Decoded active-LOW output 14. Asserts LOW when A3:A0 = 1110 and both enables are LOW. |+| 17 | Y15 | output | Decoded active-LOW output 15. Asserts LOW when A3:A0 = 1111 and both enables are LOW. |+| 18 | E2 | input | Active-LOW enable input 2. Both E1 and E2 must be LOW to enable the decoder; otherwise all Y outputs are forced HIGH. |+| 19 | E1 | input | Active-LOW enable input 1. Both E1 and E2 must be LOW to enable the decoder; otherwise all Y outputs are forced HIGH. |+| 20 | A3 | input | Binary address input bit 3 (MSB). CMOS-level logic input selecting one of the sixteen Y outputs when the device is enabled. |+| 21 | A2 | input | Binary address input bit 2. CMOS-level logic input selecting one of the sixteen Y outputs when the device is enabled. |+| 22 | A1 | input | Binary address input bit 1. CMOS-level logic input selecting one of the sixteen Y outputs when the device is enabled. |+| 23 | A0 | input | Binary address input bit 0 (LSB). CMOS-level logic input selecting one of the sixteen Y outputs when the device is enabled. |+| 24 | VCC | power_in | Positive supply voltage input, 2 V to 6 V operating range.
