The maximum power supply ripple voltage should be. The control function implementation minimizes external timing requirements.
Lead Pb – Free. Feedback to the operator ismechanism.
The package should not be opened except in a static free environment. Do not apply a signal to any bus terminal when it isbriefly, lead to deterioration in IC performance or even destruction. However, it is more expensive than the discrete solution. A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.
The device should not be operated at these iimits.

Both serial and parallel interfaces aremicroprocessor for data processing. The device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic level at the direction control DIR input. No abstract text available Text: The parallel interface can be connected to a tri-level bus through a 74LS ordirectly by the IC 74le245, with signals generated by successful decodes or can be controlled by the host system.

The maximum current draw is 19mA. The parametric values defined in the “Electrical Characteristics” table are not guaranteed at the absolute maximum ratings.
The maximum current draw is 19 mA. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Do not apply a signal to anyany of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even4.
