WebFeb 27, 2012 · The TTL gate will output between 2.4v [V OH min.] and 3.3v [V OH max.] for a high level (depending on the logic family). The CMOS gate requires a minimum of 3.7 volts to register a high. The Pull-Up resistor increases the output voltage from the TTL driver. The resistor allows the TTL chip to deive a CMOS chip. WebApr 8, 2024 · 对于芯片的电路设计不仅仅只是面向的是模拟电路,更多的是数模混合电路,对于数字电路而已,使用的cmos电路是比ttl电路要更加优越一些,因为它的静态功耗极低,对于ttl而言,以与非门为例,它需要对bjt管子进行电流偏置,才可以让它实现与非门的功能,而cmos却可以做到不使用静态功耗的前提 ...
