CY74FCT377T中文资料具有使能端的八路 D 型触发器数据手册TI规格书

描述 Description

The \\x92FCT377T devices have eight triggered D-type flip-flops with individual data (D) inputs. The common buffered clock (CP) inputs load all flip-flops simultaneously when the clock-enable (CE\\) input is low. The register is fully edge triggered. The state of each D input at one setup time before the low-to-high clock transition is transferred to the corresponding flip-flop output (O). CE\\ must be stable only one setup time prior to the low-to-high clock transition for predictable operation. 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.
