12 This octal line driver/MOS driver is designed 10 11 drive the capacitive input characteristics of MOS devices and to have the performance of the popular SN74ALS240 series. At the same time, this device offers a pinout with inputs and outputs on opposite sides of the package. This arrangement greatly facilitates printed-circuit-board layout.

The 3-state output-control gate a 2-input NOR. If either output-enable or OE2) input is high, all eight outputs are in the high-impedance state. The SN74ALS2541 provides true data at the outputs. The SN74ALS2541 is characterized for operation from to 70°C.

This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
