CY74FCT2244AT 具有三态输出和串联阻尼电阻的八路缓冲器/线路驱动器

CY74FCT2244AT 描述

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
