DESCRIPTION

The DG2720 is 2 Port high speed analog switch optimized

for USB 2.0 signal switching. The DG2720 switch is

configured in DPDT. It handles bidirectional signal flow,

achieving a 620 MHz -3 dB bandwidth with 5 pF load, and a

port to port Crosstalk and isolation at -49 dB.

Processed with high density sub micron CMOS, the

DG2720 provide low parasitic capacitance. Signals are

routed with minimized phase distortion and attain a bit to bit

skew is as low as 40 pS.

The DG2720 is designed for a wide range of operating

voltages, from 2.7 V to 4.3 V that can be driven directly from

one cell Li-ion battery. On-chip circuitry protects against

conditions when either the D+/D- lines are shorted to the

VBUS at the USB port. Additionally, logic control pins (S and

OE) can tolerate the presence of voltages that are above the

supply power rail (V+). The control logic threshold is

guaranteed to be (VIH = 1.3 V/min).

Latch up current is greater than 300 mA, as per JESD78, and

its ESD tolerance exceeds 8 kV.

Packaged in ultra small miniQFN-10 (1.4 mm x 1.8 mm x

0.55 mm), it is ideal for portable high speed mix signal

switching application.

As a committed partner to the community and the

environment, Vishay Siliconix manufactures this product

with lead (Pb)-free device termination. The miniQFN-10

package has a nickel-palladium-gold device termination

and is represented by the lead (Pb)-free “-E4” suffix to the

ordering part number. The nickel-palladium-gold device

terminations meet all JEDEC? standards for reflow and MSL

rating.

As a further sign of Vishay Siliconix's commitment, the

DG2720 is fully RoHS complaint.
