ttl电平与cmos电平的区别 晶体管组成了TTL集成电路,TTL大多采用5V电路。用二进制来进行表示的话, 5V正好等于逻辑上的“1”, 0V等于逻辑上的“0”,因此, TTL电平在电路中得以被大星应用。而在此领域中,同样被大量应用的还有CMOS电平。除了逻辑电平范围的不同,TTL电平和CMOS电平之间还有哪些不同呢? 2019-08-19...

There is a substantial difference in the voltage level range for both. For TTL it is 4.75 V to 5.25 V while for CMOS it ranges between 0 to 1/3 VDD at a low level and 2/3VDD to VDD at high levels. CMOS technology ismore economicaland preferred more as compared to the TTL logic....
