TERMINOLOGY
V
DD
Most positive power supply potential.
GND Ground (0 V) reference.
S Source terminal. May be an input or output.
D Drain terminal. May be an input or output.
IN Logic control input.
R
ON
Ohmic resistance between D and S.
R
FLAT(ON)
Flatness is defined as the difference between
the maximum and minimum value of on resis-
tance as measured over the specified analog
signal range.
I
S
(OFF) Source leakage current with the switch “OFF.”
I
D
(OFF) Drain leakage current with the switch “OFF.”
I

, I
S
(ON) Channel leakage current with the switch “ON.”
V
D
(V
S
) Analog voltage on terminals D and S.
C
S
(OFF) “OFF” switch source capacitance.
C
D
(OFF) “OFF” switch drain capacitance.
C

, C
S
(ON) “ON” switch capacitance.
t
ON
Delay between applying the digital control
input and the output switching on. See Test
Circuit 4.
t
OFF
Delay between applying the digital control
input and the output switching off.
Off Isolation A measure of unwanted signal coupling
through an “OFF” switch.
Charge A measure of the glitch impulse transferred from
Injection the digital input to the analog output during
switching.
Bandwidth The frequency at which the output is attenu-
ated by –3 dBs.
On Response The frequency response of the “ON” switch.
Insertion Loss Loss due to the ON resistance of the switch.
V
INL
Maximum input voltage for Logic “0.”
V
INH
Minimum input voltage for Logic “1.”
I
INL
(I
INH
) Input current of the digital input.
I
DD
Positive supply current.
