Description

This SN74ALS746 octal buffer and line driver is designed to have the performance of the 4ALS240A and, at the same time, offers a pinout with inputs and outputs on opposite sides of the package. This arrangement facilitates printed-circuit-board layout. In addition, 20-kW resistors have been added between all inputs and VCC. This eliminates adding external resistors in applications where the data bus must be at a high level when all other connecting devices are at a high-impedance state.

The 3-state control gate of SN74ALS746 is a 2-input NOR such that if either output-enable (OE1 or OE2) input is high, all eight outputs are in the high-impedance state.

The SN74ALS746 provides inverted data at the outputs.

The SN74ALS746 is characterized for operation from 0°C to 70°C.
