description
The CY74FCT2244T is an octal buffer and line driver that includes on-chip 25-
terminating resistors at each
of the outputs to minimize noise resulting from reflections or standing waves in high-performance applications.
The on-chip resistors reduce overall board space and component count. Designed to be employed as a memory
address driver, clock driver, and bus-oriented transmitter/receiver, this device provides speed and drive
capabilities commensurate with its fastest bipolar logic counterparts, while reducing power dissipation. The
input and output voltage levels allow direct interface with TTL, NMOS, and CMOS devices, without the need
for external components.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
