74F540 • 74F541

Octal Buffer/Line Driver with 3-STATE Outputs

General Description

The 74F540 and 74F541 are similar in function to the

74F240 and 74F244 respectively, except that the inputs

and outputs are on opposite sides of the package (see

Connection Diagrams). This pinout arrangement makes

these devices especially useful as output ports for micro-

processors, allowing ease of layout and greater PC board

density.

Features

s 3-STATE outputs drive bus lines

s Inputs and outputs opposite side of package, allowing

easier interface to microprocessors

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
