OCTAL BUFFERS AND LINE DRIVERS

WITH 3-STATE OUTPUTS

SDAS025D – APRIL 1982 – REVISED MARCH 2002

POST OFFICE BOX 655303 • DALLAS, TEXAS 75265

3-State Outputs Drive Bus Lines or Buer

pnp Inputs Reduce dc Loading

Data Flowthrough Pinout (All Inputs on

Opposite Side From Outputs)

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.
