74HCT 系列 5 V 表面贴装 单路 总线缓冲器/线路驱动器 三态 - TSSOP-5
The is a high-speed Si-gate CMOS Bus Buffer/Line Driver with 3-state output. The 3-state output is controlled by the output enable input pin OE. A HIGH level at pin OE causes the output to assume a high-impedance OFF-state. The bus driver output currents are equal compared to the 74HCT125.
