Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OE | input | Output enable input (active LOW); a HIGH level on 1OE puts outputs 1Y0 to 1Y3 into the high-impedance OFF-state. |
| 2 | 1A0 | input | Data input 1A0; the device accepts 3.3 V or 5 V driver levels and its inputs are overvoltage tolerant to 5.5 V. |
| 3 | 2Y0 | tri_state | 3-state data output 2Y0 of the 2OE-controlled buffer section; high-impedance when 2OE is HIGH. |
| 4 | 1A1 | input | Data input 1A1; the device accepts 3.3 V or 5 V driver levels and its inputs are overvoltage tolerant to 5.5 V. |
| 5 | 2Y1 | tri_state | 3-state data output 2Y1 of the 2OE-controlled buffer section; high-impedance when 2OE is HIGH. |
| 6 | 1A2 | input | Data input 1A2; the device accepts 3.3 V or 5 V driver levels and its inputs are overvoltage tolerant to 5.5 V. |
| 7 | 2Y2 | tri_state | 3-state data output 2Y2 of the 2OE-controlled buffer section; high-impedance when 2OE is HIGH. |
| 8 | 1A3 | input | Data input 1A3; the device accepts 3.3 V or 5 V driver levels and its inputs are overvoltage tolerant to 5.5 V. |
| 9 | 2Y3 | tri_state | 3-state data output 2Y3 of the 2OE-controlled buffer section; high-impedance when 2OE is HIGH. |
| 10 | GND | power_in | Ground (0 V) reference for all voltages on the device. |
| 11 | 2A3 | input | Data input 2A3; the device accepts 3.3 V or 5 V driver levels and its inputs are overvoltage tolerant to 5.5 V. |
| 12 | 1Y3 | tri_state | 3-state data output 1Y3 of the 1OE-controlled buffer section; high-impedance when 1OE is HIGH. |
| 13 | 2A2 | input | Data input 2A2; the device accepts 3.3 V or 5 V driver levels and its inputs are overvoltage tolerant to 5.5 V. |
| 14 | 1Y2 | tri_state | 3-state data output 1Y2 of the 1OE-controlled buffer section; high-impedance when 1OE is HIGH. |
| 15 | 2A1 | input | Data input 2A1; the device accepts 3.3 V or 5 V driver levels and its inputs are overvoltage tolerant to 5.5 V. |
| 16 | 1Y1 | tri_state | 3-state data output 1Y1 of the 1OE-controlled buffer section; high-impedance when 1OE is HIGH. |
| 17 | 2A0 | input | Data input 2A0; the device accepts 3.3 V or 5 V driver levels and its inputs are overvoltage tolerant to 5.5 V. |
| 18 | 1Y0 | tri_state | 3-state data output 1Y0 of the 1OE-controlled buffer section; high-impedance when 1OE is HIGH. |
| 19 | 2OE | input | Output enable input (active LOW); a HIGH level on 2OE puts outputs 2Y0 to 2Y3 into the high-impedance OFF-state. |
| 20 | VCC | power_in | Power supply; recommended operating range is 1.65 V to 3.6 V (functional down to 1.2 V). |
