3 1Y tri_state 3-state data output of buffer 1, which can sink or source 8mA at VCC = 4.5V.
4 2OE input Active-low data enable for buffer 2; a high level on this pin places output 2Y in the high-impedance state.
5 2A input Data input for buffer 2; the input is Schmitt-trigger action and is tolerant to 5.5V.
6 2Y tri_state 3-state data output of buffer 2, which can sink or source 8mA at VCC = 4.5V.
7 GND power_in Ground reference for the device.
8 3Y tri_state 3-state data output of buffer 3, which can sink or source 8mA at VCC = 4.5V.
9 3A input Data input for buffer 3; the input is Schmitt-trigger action and is tolerant to 5.5V.
10 3OE input Active-low data enable for buffer 3; a high level on this pin places output 3Y in the high-impedance state.
11 4Y tri_state 3-state data output of buffer 4, which can sink or source 8mA at VCC = 4.5V.
12 4A input Data input for buffer 4; the input is Schmitt-trigger action and is tolerant to 5.5V.
13 4OE input Active-low data enable for buffer 4; a high level on this pin places output 4Y in the high-impedance state.
14 VCC power_in Supply voltage, specified from 2.0V to 5.5V.
