D 3-State Outputs Drive Bus Lines or Buffer
Memory Address Registers
D pnp Inputs Reduce dc Loading D Data Flowthrough Pinout (All Inputs on
Opposite Side From Outputs)
description
These octal buffers and line drivers are designed to have the performance of the popular SN54ALS240A/ SN74ALS240A series and, at the same time, offer a pinout with inputs and outputs on opposite sides of the package. This arrangement greatly facilitates printed circuit board layout.
The 3-state control gate is a 2-input NOR gate such that, if either output-enable (OE1 or OE2) input is high, all eight outputs are in the high-impedance state.
The SN74ALS540 provides inverted data. The ’ALS541 provide true data at the outputs.
