description

These octal buers and line drivers are designed

to have the performance of the popular

SN54ALS240A/SN74ALS240A series and, at

the same time, oer 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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
