54FCT540

Octal Buffer/Line Driver with TRI-STATE^®Outputs

General Description

The ’FCT540 is an octal buffer/line drivers designed to be

employed as memory and address drivers, clock drivers and

bus oriented transmitter/receivers.

Features

n TRI-STATE inverting outputs

n Inputs and outputs opposite side of package, allowing

easier interface to microprocessors

n TTL input and output level compatible

n CMOS power consumption

n Output sink capability of 48mA, source capability of 12

These devices are similar in function to the ’FCT240 while

providing flow-through architecture (inputs on opposite side

from outputs). This pinout arrangement makes these devices

especially useful as output ports for microprocessors, allow-

ing ease of layout and greater PC board density.
