OCTAL BUFFERS AND LINE DRIVERS WITH 3-STATE OUTPUTS

These octal Buffers and Line Drivers SN54ALS541 SN74ALS540 SN74ALS541 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. 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. By Texas Instruments
