When OE is low, the buffer passes A to Y; when OE is high, Y is placed in a high-impedance (3-state) condition. TTL-compatible input, VIH >= 2 V, VIL <= 0.8 V. |-| 2 | A | input | Data input to the buffer. Value is driven to Y when OE is low.

When OE is low, the buffer passes A to Y; when OE is high, the Y output is placed in a high-impedance (3-state) condition.
