TI 的 CD74HCT74 是一款 具有设置和复位功能的高速 CMOS 逻辑双通道上升沿 D 触发器。 查找参数、订购和质量信息.

To simplify interfacing of TTL outputs to high-speed CMOS inputs, Texas Instruments (TI) introduced HCT circuits, a subgroup of its HC family. HCT features and functions are identical to HC devices with the exception of modified input circuitry, which makes the input threshold voltage compatible with TTL circuits.

TI’s SN74HCT74 is a Dual D-Type Positive-Edge-Triggered Flip-Flops With Clear and Preset. Find parameters, ordering and quality information.

The CD74HCT30 can drive a load with a total capacitance less than or equal to the maximum load listed in the Section 6.5 connected to a high-impedance CMOS input while still meeting all of the datasheet specifications. Larger capacitive loads can be applied, however it is not recommended to exceed the provided load value.

请问下有没有人用过74hctXX系列 想要用这个升压 请问有没有相关的电路图可以学习下呢？ 就是DSP3.3V想要用来升压到12V来给下面的图腾柱电路的的VCC端的

2019年3月15日 · RESET是开机上电复位信号，当开机上电复位电源电压不稳定的时候，一直为低电平，从而D991输入为低，输出为高，错误信号ERROR为高电平，无错误。 当电压稳定时，若各路监测信号无故障，D906各路输入电平为高电平，输出为低电平。 然后D906的8脚输出为高（非运算特性），这时候由于D911 的4，5脚输入为高，而D911的1,2脚就是D90..._74hcxx与非门.
