Vishay Siliconix
2 Port, USB 2.0 High Speed (480 Mbps) Switch,
DPDT Analog Switch
DESCRIPTION
FEATURES
•
•
•
•
Wide operation voltage range
Low on-resistance, 5.7 Ω (typical at 3 V)
Low capacitance, 5.6 pF (typical)
3 dB high bandwidth with 5 pF load:
620 MHz (typical)
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.
RoHS
COMPLIANT
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.

Low bit to bit skew: 40 pS (typical)
Low power consumption
Low logic threshold: V
Power down protection: D+/D- pins can tolerate up to
5 V when V+ = 0 V
Logic (S and OE) above V+ tolerance
Latch-up current greater than 300 mA per JESD78
8 kV ESD protection (HBM)
