G7 SGS-THOMSON T74LS365A/366A J ivickozsevromics _- T74LS367A/368A 3-STATE HEX BUFFERS DESCRIPTION — These devices are high-speed Hex Butfers with 3- Lier state outputs. They are organized as single 6-bit or , , 2-biv/4-bit, with inverting or non-inverting data (D) iit yy paths. The outputs are designed to drive 15 TTL Unit vy ! Loads or 60 Low Power Schottky loads when the 8} Dt Enable (F) Is LOW. _ (Plastic Package) (Ceramic Package} When the output Enable input (E) is HIGH, the out- . puts are forced toa high impedance “oft” state. I the “ “a outputs of the 3-state devices are tied together, all but one device must be in the high impedence state Mt 1 to avoid high currents that woud exceed the maxi- (Micro Package) (Plastic Chip Carrier) mum ratings. Designers should ensure that Output ORDER CODES : Enable signals to 3-state devices, whose outputs T7ALSXXXX D1 T74L SXXXX C1 are tied together, are designed so there is no over- T7ALSXXXX Bt T74LSXXXX M1 lap.
