3-State Hex Buffers

These devices are high speed hex buffers with 3-state outputs. They

are organized as single 6-bit or 2-bit / 4-bit, with inverting or

non-inverting data (D) paths. The outputs are designed to drive 15

TTL Unit Loads or 60 Low Power Schottky loads when the Enable (E)

is LOW.

When the Output Enable (E) is HIGH, the outputs are forced to a

high impedance “off” state. If the outputs of the 3-state devices are tied

together, all but one device must be in the high impedance state to

avoid high currents that would exceed the maximum ratings.

Designers should ensure that Output Enable signals to 3-state devices

whose outputs are tied together are designed so there is no overlap.
