The ’AC541 is a noninverting option of the ’AC540. This device is similar in function to the ’AC244 while providing flow-through architecture (inputs on opposite side from outputs). This pinout arrangement makes this device especially useful as an output port for microprocessors, allowing ease of layout and greater PC board density. Features n ICC and IOZ reduced by 50% n TRI-STATE outputs n Inputs and outputs opposite side of package, allowing easier interface to microprocessors n Output source/sink 24 mA n ’AC540 provides inverted outputs n Standard Military Drawing (SMD) — ’AC541: 5962-88706 Logic Symbol IEEE/IEC DS100330-3 Truth Table Inputs OE1 L H X L H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial Z = High Impedance Outputs I H X X L H Z Z L OE2 L X H L TRI-STATE ® is a registered trademark of National Semiconductor Corporation.
