Frequently Asked Questions
What is the primary function of this multiplexer chip?
It multiplexes 16 digital lines down to a single output using a 4-bit address code, with data inverted from input to output.
What specific voltage range can I use for operation?
The device supports a wide supply voltage range, operating between 3.0V and 15V.
How is the chip protected from electrostatic damage?
All inputs are protected from static charge by built-in diode clamps connecting to V and GND.
What are the guaranteed noise immunity levels?
It features a guaranteed noise margin of 1.0V for logical ‘1’ state and 0.45V (typ.) for the high impedance state.
Does the output include an override feature?
Yes, the device includes a strobe override function that can place the output in a specific impedance state.
