Supply voltage; the most positive potential on
the device.
Supply voltage; for a device with a single
negative power supply, the most negative
power supply, used as the reference level for
other voltages; typically ground.
Supply voltage; one of two (V
negative power supplies. For a device with dual
negative power supply, the most negative
power supply as a reference level for other
voltages.
Input voltage HIGH; the range of input voltages
that represents a logic HIGH level in the
system.
Input voltage LOW; the range of input voltages
that represents a logic LOW level in the system.
Output voltage HIGH; the range of voltages at
an output terminal with a specified output
loading and supply voltage. Device inputs are
conditioned to establish a HIGH level at the
output.
Output voltage LOW; the range of voltages at
an output terminal with a specified output
loading and supply voltage. Device inputs are
conditioned to establish a LOW level at the
output.
Trigger threshold voltage; positive-going signal.
Trigger threshold voltage; negative-going
signal.
ON resistance; the effective ON state
resistance of an analogue transmission gate, at
specified input voltage, output load and V
resistance between any two transmission gates
of an analogue device at specified input
voltage, output load and V
ON resistance; the difference in effective ON
