资 源 简 介

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.
