1. M MOTOROLA 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 GUARANTEED OPERATING RANGES FAST AND LS TTL DATA 5 1 SN54 74LS365A SN54 74LS366A SN54 74LS367A SN54 74LS368A 3 STATE HEX BUFFERS LOW POWER SCHOTTKY J SUFFIX CERAMIC CASE 620 09 N SUFFIX PLASTIC CASE 648 08 D SUFFIX SOIC CASE 751B 03 ORDERING INFORMATION SN54LSXXXJ Ceramic SN74LSXXXN Plastic SN74LSXXXD SOIC SN54 74LS365A SN54 74LS366A SN54 74LS367A SN54 74LS368A SN54 74LS365A SN54 74LS366A HEX 3 STATE BUFFER WITH HEX 3 STATE INVERTER BUFFER COMMON 2 INPUT NOR ENABLE WITH COMMON 2 INPUT NOR ENABLE INPUTS E OUTPUT L L H X SN54 74LS367A SN54 74LS368A HEX 3 STATE BUFFER HEX 3 STATE INVERTER BUFFER SEPARATE 2 BIT AND 4 BIT SECTIONS SEPARATE 2 BIT AND 4 BIT SECTIONS TRUTH2.
