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 ...

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 ...

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 ...

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, ...

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 ...
