Integrated Circuit
TTL − Hex Bus Driver with 3−State Outputs
Description:
The NTE74367 is a hex bus driver in a 16−Lead plastic DIP type package designed specifically to
improve both the performance and density of three−state memory address drivers, clock drivers, and
bus oriented receivers and transmitters. The designer has a choice of selected combinations of inverting and non−inverting outputs, symmetrical G (active−low control) inputs.
This device features high fan−out, improved fan−in, and can be used to drive terminated lines down
to 133 ohms.
Features:
D 3−State Outputs Drive Bus Lines or Buffer Memory Address Registers
D Non−Inverting Outputs
