Part Description: 74AC540 Octal Buffer Line Driver with 3-STATE Outputs

Part Details:

74AC November 1988 Revised March 2005 540 Oct 74AC540 al Buf Octal Buffer/Line Driver with 3-STATE Outputs fer General Description Features /Li The AC540 is an octal buffer/line drivers designed to be s ICC and IOZ reduced by 50% employed as memory and address drivers, clock drivers ne s 3-STATE inverting outputs and bus oriented transmitter/receivers. s Inputs and outputs opposite side of package, allowing Dri These devices are similar in function to the AC240 while easier interface to microprocessors providing flow-through architecture (inputs on opposite side ver s from outputs). This pinout arrangement makes these Output source/sink 24 mA devices especially useful as output ports for microproces- w sors, allowing ease of layout and greater PC board density. ith 3- Ordering Code: ST Order Number Package Number Package Description AT 74AC540SC M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide E 74AC540SJ M20D Pb-Free 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide O 74AC540MTC MTC20 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide utput 74AC540PC N20A 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Device also available in Tape and Reel.
