Data Sheet
TERMINOLOGY
IDD
Positive supply current.
VD,VS
Analog voltage on Terminal D and Terminal S.
RON
Ohmic resistance between Terminal D and Terminal S.
RFLAT (On)
The difference between the maximum and minimum values of
on resistance as measured on the switch.
∆RON
On resistance match between any two channels.
IS (Off)
Source leakage current with the switch off.
ID (Off)
Drain leakage current with the switch off.
ID, IS (On)
Channel leakage current with the switch on.
VINL
Maximum input voltage for Logic 0.
VINH
Minimum input voltage for Logic 1.
IINL,IINH
Input current of the digital input.
CS (Off)
Off switch source capacitance. Measured with reference
to ground.
CD (Off)
Off switch drain capacitance. Measured with reference
to ground.
CD, CS (On)

CIN
Digital input capacitance.
tON
Delay time between the 50% and 90% points of the digital input
and switch on condition.
tOFF
Delay time between the 50% and 90% points of the digital input
and switch off condition.
tBBM
On or off time measured between the 80% points of both
switches when switching from one to another.
Charge Injection
Measure of the glitch impulse transferred from the digital input
to the analog output during on/off switching.
Off Isolation
Measure of unwanted signal coupling through an off switch.
Crosstalk
Measure of unwanted signal that is coupled from one channel to
another as a result of parasitic capacitance.
−3 dB Bandwidth
Frequency at which the output is attenuated by 3 dB.
On Response
Frequency response of the on switch.
Insertion Loss
The loss due to the on resistance of the switch.
THD + N
Ratio of the harmonics amplitude plus noise of a signal to the
fundamental.
TSKEW
The measure of the variation in propagation delay between each
channel.
