SN74AHCT74-EP中文资料具有清零和预置端的增强型产品双路正边沿触发式 D 型触发器数据手册TI规格书

描述 Description

The SN74AHCT74 is a dual positive-edge-triggered D-type flip-flop.

A low level at the preset (PRE)\\ or clear (CLR)\\ inputs sets or resets the outputs, regardless of the levels of the other inputs. When PRE\\ and CLR\\ are inactive (high), data at the data (D) input meeting the setup time requirements is transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of the clock pulse. Following the hold-time interval, data at the D input can be changed without affecting the levels at the outputs.

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. EPIC is a trademark of Texas Instruments.
