DESCRIPTION

configured in dual SPDT.

It achieves 5.7

Ω switch on resistance, greater than

500 MHz - 3 dB bandwidth with 5 pF load, and a channel to

channel crosstalk and Isolation at - 49 dB.

Fabricated with high density sub micro CMOS process, the

DG2721

provides

low

parasitic

capacitance,

handles

bidirectional signal flow with minimized phase distortion.

Guaranteed 1.3 V logic high threshold makes it possible to

interface directly with low voltage MCUs.

The DG2721 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 protection circuit protects

again fault events when signals at “com” pins goes beyond

V+.

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

DG2721 is fully RoHS complaint.
