Description

These octal buffers and line drivers of SN54ALS541 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-circuitboard layout.

The 3-state control gate 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 SN74ALS540 provides inverted data. The 4ALS541 provide true data at the outputs. The -1 versions of SN74ALS540 and SN74ALS541 are identical to the standard versions, except that the recommended maximum IOL is increased to 48 mA. There is no -1 version of the SN54ALS541.

The SN54ALS541 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74ALS540 and SN74ALS541 are characterized for operation from 0°C to 70°C.
