Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OE | input | Buffer 1 output enable, active high. When high, buffer 1 output (1Y) follows 1A; when low, 1Y is placed in the high-impedance (Z) state. Schmitt-trigger input, 5.5V tolerant. |
| 2 | 1A | input | Buffer 1 data input. Schmitt-trigger input, 5.5V tolerant. Propagated to 1Y when 1OE is high. |
| 3 | 1Y | tri_state | Buffer 1 3-state data output. Sinks/sources 8mA at VCC = 4.5V. High-Z when 1OE is low. |
| 4 | 2OE | input | Buffer 2 output enable, active high. When high, 2Y follows 2A; when low, 2Y is placed in the high-impedance (Z) state. Schmitt-trigger input, 5.5V tolerant. |
| 5 | 2A | input | Buffer 2 data input. Schmitt-trigger input, 5.5V tolerant. Propagated to 2Y when 2OE is high. |
| 6 | 2Y | tri_state | Buffer 2 3-state data output. Sinks/sources 8mA at VCC = 4.5V. High-Z when 2OE is low. |
| 7 | GND | power_in | Ground reference (0 V). Continuous current through GND rated to -75 mA (abs. max). |
| 8 | 3Y | tri_state | Buffer 3 3-state data output. Sinks/sources 8mA at VCC = 4.5V. High-Z when 3OE is low. |
| 9 | 3A | input | Buffer 3 data input. Schmitt-trigger input, 5.5V tolerant. Propagated to 3Y when 3OE is high. |
| 10 | 3OE | input | Buffer 3 output enable, active high. When high, 3Y follows 3A; when low, 3Y is placed in the high-impedance (Z) state. Schmitt-trigger input, 5.5V tolerant. |
| 11 | 4Y | tri_state | Buffer 4 3-state data output. Sinks/sources 8mA at VCC = 4.5V. High-Z when 4OE is low. |
| 12 | 4A | input | Buffer 4 data input. Schmitt-trigger input, 5.5V tolerant. Propagated to 4Y when 4OE is high. |
| 13 | 4OE | input | Buffer 4 output enable, active high. When high, 4Y follows 4A; when low, 4Y is placed in the high-impedance (Z) state. Schmitt-trigger input, 5.5V tolerant. |
| 14 | VCC | power_in | Positive supply voltage. Recommended operating range 2.0V to 5.5V; absolute maximum -0.5V to +7.0V. Continuous current through VCC rated to 75 mA (abs. max). |
