description
The CY74FCT2541T is an octal buffer and line driver designed to be employed as a memory-address driver,
clock driver, and bus-oriented transmitter/receiver. On-chip termination resistors at the outputs reduce system noise
caused by reflections. The CY74FCT2541T can replace the CY74FCT541T to reduce noise in an existing design.
The speed of the CY74FCT2541T is comparable to bipolar logic counterparts, while reducing power dissipation.
Input and output voltage levels allow direct interface with TTL and CMOS devices without 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.

Stresses beyond those listed under absolute maximum ratingsmay cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditionsis not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The package thermal impedance is calculated in accordance with JESD 51-7.
