32 mA (Com’l), 12 mA (Mil)
• Extended commercial range of −40˚C to +85˚C
Functional Description
The FCT540T inverting buffer/line driver and the FCT541T
non-inverting buffer/line driver are designed to be employed as
memory address drivers, clock drivers, and bus-oriented
transmitters/receivers. The devices provide speed and drive
capabilities equivalent to their fastest bipolar logic
counterparts while reducing power dissipation. The input and
output voltage levels allow direct interface with TTL, NMOS,
and CMOS devices without external components.
The outputs are designed with a power-off disable feature to
allow for live insertion of boards.
