OCTAL BUFFER/LINE DRIVER WITH 3-STATE OUTPUTS ! The MC74AC540/74ACT540 and MC74AC541/74ACT541 are octal buffer/line drivers designed to be employed as memory and address drivers, clock drivers and bus oriented transmitter/receivers. The MC74AC541/74ACT541 is a noninverting option of the MC74AC540/74ACT540. These devices are similar in function to the MC74AC240/74ACT240 and MC74AC244/74ACT244 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. * 3-State Outputs * Inputs and Outputs Opposite Side of Package, Allowing Easier Interface to Microprocessors * Outputs Source/Sink 24 mA * MC74AC540/74ACT540 Provides Inverted Outputs * MC74AC541/74ACT541 Provides Noninverted Outputs * ACT540 and ACT541 Have TTL Compatible Inputs MC74AC540/74ACT540 OE1 N SUFFIX CASE 738-03 PLASTIC MC74AC541/74ACT541 1 20 VCC 2 19 OE2 3 18 OE1 DW SUFFIX CASE 751D-04 PLASTIC 1 20 VCC 2 19 OE2 3 18 TRUTH TABLE GND 4 17 4 17 5 16 5 16 6 15 6 15 7 14 7 14 8 13 8 13 9 12 9 12 10 11 10 11 GND FACT DATA 5-1 Inputs Outputs OE1 OE2 D 540 541 L H X L L X H L H X X L L Z Z H H Z Z L H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial Z = High Impedance MC74AC540 MC74ACT540 MC74AC541 MC74ACT541 MAXIMUM RATINGS* Symbol Parameter Value Unit -0.5 to +7.0 V V VCC DC Supply Voltage (Referenced to GND) Vin DC Input Voltage (Referenced to GND) -0.5 to VCC +0.5 Vout DC Output Voltage (Referenced to GND) -0.5 to VCC +0.5 V Iin DC Input Current, per Pin 20 mA Iout DC Output Sink/Source Current, per Pin 50 mA ICC DC VCC or GND Current per Output Pin 50 mA Tstg Storage Temperature -65 to +150 C * Maximum Ratings are those values beyond which damage to the device may occur.
