The Input Low Voltage (V
read a ’0’ at a voltage level above this. All designs should be to the specification since device to
device (and to a much lesser extent pin to pin) variations will cause this level to vary.
The Input High Voltage (V
read a ’1’ at a voltage level below this. All designs should be to the specification since device to
device (and to a much lesser extent pin to pin) variations will cause this level to vary.
The I/O pins with TTL levels are shown with two specifications. One is the industry standard TTL
specification, which is specified for the voltage range of 4.5V to 5.5V. The other is a specification
that operates over the entire voltage range of the device. The better of these two specifications
may be used in the design.
