DESCRIPTION

The DG2722 is 2 port high speed analog switch optimized for

USB 2.0 signal switching. The DG2722 switch is configured

in DPDT. It handles bidirectional signal flow, achieving a

900 MHz - 3 dB bandwidth, and a port to port crosstalk and

isolation at - 49 dB.

Processed with high density sub micron CMOS, the DG2722

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 DG2722 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

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

DG2722 is fully RoHS complaint.
