single-pole-single-throw analog switches are designed to
provide high speed, low error switching of analog signals.
The DG441LE has a normally closed function. The DG442LE
has a normally open function.
FEATURES
• 3 V to 16 V single supply or 3 V to 8 V dual
supply
• On-resistance RDS(on): 16
• Fast switching tON: 18 ns,typ.
• Low parasitic capacitance:

Available
CD(ON): 15 pF
CS(OFF): 5 pF
• Less than 8 pC charge injection over the full
signal swing range
• Low leakage: < 10 pA, typ.
• TTL, CMOS compatible
• Material categorization: for definitions of compliance

Note
The DG441LE, DG442LE feature low charge injection of a
few picocoulombs over the full analog switch range.
Combining low on resistance (16 , typ.), low parasitic
capacitance (CD(ON) 15 pF), and fast switching speed
(tON, 18 ns, typ.), the devices are ideal for data acquisition,
sample-and-hold, and ADC input circuit designs.
Available
The DG441LE, DG442LE operate on single and dual
supplies. Single supply voltage ranges from 3 V to 16 V while
dual supply operation is recommended with 3 V to 8 V.
Each switch conducts equally well in both direction when
on, and blocks input voltages up to the supply levels when
off.
