3-STATE HEX BUFFERS SN54/74LS367A
SN54/74LS368A
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 3-STATE HEX BUFFERS
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 LOW POWER SCHOTTKY
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.
