DESCRIPTION

The DG2730 is 2 port high speed analog switch optimized

for USB 2.0 signal switching. The DG2730 switch is

configured in DPDT. It handles bidirectional signal flow,

achieving a 900 MHz -3 dB bandwidth, a port to port

crosstalk at -36 dB and isolation at -29 dB, measured at

240 MHz.

Processed with high density sub micron CMOS, the

DG2730 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 DG2730 is designed for a wide range of operating

voltages, from 2.7 V to 5.5 V that can be driven directly

from one cell Li-ion battery or 5 V power supply. On-chip

circuitry protects against conditions when either the D+ / Dlines

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

up to V+ = 3.6 V). Latch up current is 500 mA, as per

JESD78, and its ESD tolerance exceeds 5.5 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 “-GE4” 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

DG2730 is fully RoHS-complaint.
