MC74AC540 MC74ACT540 MC74AC541 MC74ACT541 OCTAL BUFFER/LINE DRIVER WITH 3-STATE OUTPUTS Octal Buffer/Line Driver with 3State 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 MC74AC541/74ACT541 N SUFFIX CASE 738-03 PLASTIC DW SUFFIX CASE 751D-04 PLASTIC VCC OE2 OE1 1 2 3 4 5 6 7 8 9 20 19 18 17 16 15 14 13 12 11 VCC OE2 OE1 1 2 3 4 5 6 7 8 9 20 19 18 17 16 15 14 13 12 11 TRUTH TABLE Inputs OE1 L H X L OE2 L X H L D H X X L Outputs ′540 L Z Z H ′541 H Z Z L H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial Z = High Impedance GND 10 GND 10 FACT DATA 5-1 MC74AC540 MC74ACT540 MC74AC541 MC74ACT541 MAXIMUM RATINGS* Symbol VCC Vin Vo……
