Typical Applications (continued)

Figure 15. Universal Logic Level Shifter

The two 10 kΩ resistors bias the input to half of the input logic supply level to set the threshold in the mid-point of

the input logic levels. Only one shared output pull-up resistor is needed and may be connected to any pull-up

voltage between 0 V and 5.5 V. The pullup voltage should match the driven logic input "high" level.

10.2.6 One-Shot Multivibrator

Figure 16. One-Shot Multivibrator

A monostable multivibrator has one stable state in which it can remain indefinitely. It can be triggered externally

to another quasi-stable state. A monostable multivibrator can thus be used to generate a pulse of desired width.

non-inverting input from being driven below ground.
