CY74FCT244DTSOCT

The ’FCT244T devices are octal buffers and line drivers designed to be employed as memory address drivers, clock drivers, and bus-oriented transmitters/receivers. These devices provide speed and drive capabilities equivalent to their fastest bipolar logic counterparts, while reducing power consumption. The input and output voltage levels allow direct interface with TTL, NMOS, and CMOS devices without external components. These devices are fully specified for partial-power-down applications using Io(overline)f(overline). The Io(overline)f(overline) circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
