2 I0 input Data input 0, 5V tolerant (VI up to 5.5V), with unused inputs required to be held HIGH or LOW.
3 I1 input Data input 1, 5V tolerant (VI up to 5.5V), with unused inputs required to be held HIGH or LOW.
4 I2 input Data input 2, 5V tolerant (VI up to 5.5V), with unused inputs required to be held HIGH or LOW.
5 I3 input Data input 3, 5V tolerant (VI up to 5.5V), with unused inputs required to be held HIGH or LOW.
6 I4 input Data input 4, 5V tolerant (VI up to 5.5V), with unused inputs required to be held HIGH or LOW.
7 I5 input Data input 5, 5V tolerant (VI up to 5.5V), with unused inputs required to be held HIGH or LOW.
8 I6 input Data input 6, 5V tolerant (VI up to 5.5V), with unused inputs required to be held HIGH or LOW.
9 I7 input Data input 7, 5V tolerant (VI up to 5.5V), with unused inputs required to be held HIGH or LOW.
10 GND power_in Ground pin; DC ground current per ground pin is limited to ±100 mA.

16 O2 tri_state 3-STATE non-inverting output 2 following I2, with ±24 mA drive at VCC = 3.0V and 5V tolerant when in 3-STATE.
17 O1 tri_state 3-STATE non-inverting output 1 following I1, with ±24 mA drive at VCC = 3.0V and 5V tolerant when in 3-STATE.
18 O0 tri_state 3-STATE non-inverting output 0 following I0, with ±24 mA drive at VCC = 3.0V and 5V tolerant when in 3-STATE.
19 OE2 input 3-STATE output enable input 2; outputs are enabled only when OE1 and OE2 are both LOW, and a HIGH on either puts the outputs in high impedance.
20 VCC power_in Supply voltage, 2.0V to 3.6V recommended operating (2.3V-3.6V specified), absolute maximum -0.5 to +7.0V.
