Abstract: A separately self-biased transistor-transistor logic (TTL)-to-CMOS input buffer (SSIB) is proposed. Its logic threshold voltage is kept at 1.4 V when supply voltage is changed from 3.3 V to ...

Dallas, TX — Texas Instruments Incorporated (TI) introduced seven pseudo emitter-coupled logic (PECL) and transistor-transistor logic (TTL) translator drivers and receivers, including the industry's ...

The 74HC00 data sheet warns that inputs must not be allowed to float because this makes the output indeterminate. Now, that in itself is a good reason, but there is more… In my previous column, we ...

The logic on-off function allows the user to shut off the converter’s output using a simple TTL logic signal or mechanical switch, and avoids having to turn off the DC input bus. This feature is ...

Self-acclaimed computer nerd [Kevin Koster] was tired of designing new TTL-logic clocks before finishing his previous designs. So he finally buckled down and completed this unique word clock, which ...

I fear the topic of this column is poised to unleash a tsunami of controversy. My engineering accomplice Joe Farr says that this is one of those topics that, when presented to 10 different engineers, ...
