1 P54FCT241T/74fct241t OCTAL BUFFER/LINE DRIVER WITH 3-STATE OUTPUTS FEATURES Function, Pinout and Drive Compatible with the FCT and F Logic FCT-A speed at 5.1ns max (MIL) Reduced VOH (typically = 3.3V) versions of equivalent FCT functions Edge-rate control circuitry for significantly improved noise characteristics ESD protection exceeds 2000V Power-off disable feature Matched rise and fall times Fully compatible with TTL input and output logic levels 48 ma sink current, 12 ma source current (MIL) DESCRIPTION The P54/74FCT241T is a non-inverting octal buffer and line driver designed to be employed as memory address drivers, clock drivers and bus-oriented transmitters/receivers. The device provides speed and drive capabilities equivalent to the fastest bipolar logic counterparts while reducing power dissipation by using advanced CMOS technoloy. The input and output voltage levels allow direct interface with TTL, NMOS and CMOS devices without external components.
