CD74HCT574-EP中文资料增强型产品高速 Cmos 逻辑八路正边沿触发式 D 型触发器，具有数据手册TI规格书

描述 Description

The CD74HCT574 is an octal D-type flip-flop with 3-state outputs and the capability to drive 15 LSTTL loads. The eight edge-triggered flip-flops enter data into their registers on the low-to-high transition of the clock (CP). The output enable (OE)\\ controls the 3-state outputs and is independent of the register operation. When OE\\ is high, the outputs are in the high-impedance state.

Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits.
