CY54FCT373T中文资料具有三态输出的八路透明 D 类锁存器数据手册TI规格书

描述 Description

The \\x92FCT373T devices consist of eight latches with 3-state outputs for bus-organized applications. When the latch-enable (LE) input is high, the flip-flops appear transparent to the data. Data that meets the required setup times are latched when LE transitions from high to low. Data appears on the bus when the output-enable (OE\\) input is low. When OE\\ is high, the bus output is in the high-impedance state. In this mode, data can be entered into the latches. These devices are 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.
