TTL levels with the logic threshold pin, VLC, grounded.

Low power consumption: m W at ±5V

Changing the VLC potential will allow direct interface to other

logic families. The performance and characteristics of the Low cost

device are essentially unchanged over the full ±4.5V to

±18V power supply range; power dissipation is only m W with ±5V supplies and is independent of the logic input states.
