May 11, 2010 · If the TTL value started at, say, 128 and you see a value of 28, then there were 100 hops between the system where the packet originated and the final destination. My guess …

May 8, 2012 · But the domain is still not getting verified. I've hit the refresh button on the 'Domain Settings' page too but to no avail. The only issue I'm having is that my domain host does not …

Aug 14, 2012 · Often any 5V logic is called TTL, although most circuits nowadays are built as CMOS. Today there are also many circuits that work at 3.3V, which is no longer TTL. With …

Dec 11, 2016 · A TTL UART will output (and input) only TTL levels, essentially 0 bit = 0V and 1 bit = 5V. And many modern-day gadgets (Arduino, et.al.) simply use TTL voltage levels for serial …

Nov 17, 2010 · Which would be different if it were really TTL, as in your question (the microcontroller is HCMOS). TTL outputs are highly asymmetrical: they can only supply little …

The "TTL" on an Arduino board means that the signals are 5 V. There is no TTL logic on an Arduino board at all. The ATMega chip on the Arduino can work at 3.3 V to 5.5 V so that …

ttl：ttl指双极型三极管逻辑电路，也可以指一种电平规范（类似的还有cmos电平等）。淘宝上很多“usb转ttl”模块，实际上是“usb转ttl电平的串口模块”。这种信号0对应0v，1对应3.3v或者5v。 …

Mar 21, 2018 · What is the difference of these two ttl nand gates? If you will carefully look at them they are functionally very same, with bottom having more elaborate circuit, with push-pull …

Feb 10, 2016 · TTL outputs must be able to sink 16 mA with a voltage drop of no more than 0.4 V, and to source 0.4 mA while staying above 2.4 V. (TTL inputs source 1.6 mA, so this is …

Mar 10, 2018 · In TTL 74LS serie, a input signal between 0 and 0.8V is considered “LOW”, and a input signal between 2.0 and 5.0V is considered “HIGH”. Any voltage between 0.8 and 2.0 …
