Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OE | input | Output enable input for buffer 1; when low, 1Y is driven by 1A; when high, 1Y is in high impedance. |
| 2 | 1A | input | Input data A for buffer 1; output 1Y follows the level of 1A when 1OE is low. |
| 3 | 1Y | tri_state | Three-state output of buffer 1; driven by 1A when 1OE is low, high impedance when 1OE is high. |
| 4 | 2OE | input | Output enable input for buffer 2; when low, 2Y is driven by 2A; when high, 2Y is in high impedance. |
| 5 | 2A | input | Input data A for buffer 2; output 2Y follows the level of 2A when 2OE is low. |
| 6 | 2Y | tri_state | Three-state output of buffer 2; driven by 2A when 2OE is low, high impedance when 2OE is high. |
| 7 | GND | power_in | Ground connection. |
| 8 | 3Y | tri_state | Three-state output of buffer 3; driven by 3A when 3OE is low, high impedance when 3OE is high. |
| 9 | 3A | input | Input data A for buffer 3; output 3Y follows the level of 3A when 3OE is low. |
| 10 | 3OE | input | Output enable input for buffer 3; when low, 3Y is driven by 3A; when high, 3Y is in high impedance. |
| 11 | 4Y | tri_state | Three-state output of buffer 4; driven by 4A when 4OE is low, high impedance when 4OE is high. |
| 12 | 4A | input | Input data A for buffer 4; output 4Y follows the level of 4A when 4OE is low. |
| 13 | 4OE | input | Output enable input for buffer 4; when low, 4Y is driven by 4A; when high, 4Y is in high impedance. |
| 14 | VCC | power_in | Positive power supply, operating voltage range 1.65 V to 3.6 V. |
