74LVTH244SJ

低压带3态输出的八路缓冲器/线路驱动器 Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs

General Description

The LVT244 and LVTH244 are octal buffers and line drivers designed to be employed as memory address drivers, clock drivers and bus oriented transmitters or receivers which provide improved PC board density.

The LVTH244 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.

Features

■Input and output interface capability to systems at 5V VCC
