FAQ: Logic and Voltage Translation > Monostable Multivibrators >> Current FAQ
The above functional block diagram shows generally how a monostable multivibrator (MMV, or one-shot) works. Not all of them have every part shown, but this is the most common…
FAQ: Logic and Voltage Translation > Logic Technology >> Current FAQ
It's very common for people to refer to "TTL logic" and to actually mean "5V logic" -- but how are they different?
The key difference is in the input and output voltages. This graphic…
FAQ: Logic and Voltage Translation > Timing Parameters >> Current FAQ
The difference in delay between the individual channels on an individual part is referred to as channel-to-channel skew or output skew. This is typically not covered as a datasheet…

The High-speed CMOS (HC) logic family was created as a direct replacement for older bipolar junction transistor based transistor…
FAQ: Logic and Voltage Translation > Input Parameters >> Current FAQ
The most common example of this question comes from the fact that Standard Logic devices are specified at 1.65V, 3V, and 4.5V, however most engineers use our devices at 1.8V, 3.3V…
FAQ: Logic and Voltage Translation > Quality and Manufacturing >> Current FAQ
TI's General Quality Guideline (page 7) describes our official policy on obsoleting a device. This policy is summarized below.
TI's Product withdrawal/discontinuance process…
FAQ: Logic and Voltage Translation > Voltage Translators >> Current FAQ
Some of the TI translators have requirements during normal operation mode to have Vcca <= Vccb ( TXS/ TXB01xx) or Vrefb>= VrefA+0.8V(LSF). However, the TI translation devices do…
FAQ: Logic and Voltage Translation > Logic Technology >> Current FAQ
The I OFF specification guarantees the I/O ports are in high impedance whenever either one of the power supply is at pulled to ground (0V) or close to gnd(<100mV as specified for the…
FAQ: Logic and Voltage Translation > Voltage Translators >> Current FAQ
For the TXB family, unused I/O ports are recommended to be tied to GND through a weak pulldown resistors (>=100kohm).
For TXS devices, the internal 10kohm pull-ups resistors will…
