74AC540 Octal Buffer/Line Driver with 3-STATE Outputs November 1988 Revised March 2005 74AC540 Octal Buffer/Line Driver with 3-STATE Outputs General Description The AC540 is an octal buffer/line drivers designed to be employed as memory and address drivers, clock drivers and bus oriented transmitter/receivers. These devices are similar in function to the AC240 while providing flow-through architecture (inputs on opposite side from outputs). This pinout arrangement makes these devices especially useful as output ports for microprocessors, allowing ease of layout and greater PC board density. Features s ICC and IOZ reduced by 50% s 3-STATE inverting outputs s Inputs and outputs opposite side of package, allowing easier interface to microprocessors s Output source/sink 24 mA Ordering Code: Order Number 74AC540SC 74AC540SJ 74AC540MTC 74AC540PC Package Number M20B M20D MTC20 N20A Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide Pb-Free 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code. Pb-Free package per JEDEC J-STD-020B.
