POST OFFICE BOX 655303
DALLAS, TEXAS 75265
PRINCIPLES OF OPERATION
The digital inputs of these devices provide TTL compatibility when operated from a supply voltage of 5V. These
devices can operate with any supply voltage in the range from 5V to 15V; however, input logic levels are not
TTL-compatible above 5V.
