DG447/448

Vishay Siliconix

Low Power, High Voltage SPST Analog Switches

DESCRIPTION

FEATURES

•

15 V Analog Signal Range

The DG447 and DG448 are dual supply single-pole/single-

throw (SPST) switches. On resistance is 25 Ω maximum and

flatness is 2.2 Ω max over the specified analog signal range.

These analog switches were designed to provide high

speed, low error switching of precision analog signals. The

primary application areas are in the routing and switching in

telecommunications and test equipment. Combining low

power, low leakages, low on-resistance and small physical

size, the DG477/448 are also ideally suited for portable and

battery powered industrial and military equipment.

On-Resistance - r_DS(on): 25 Ω max

Fast Switching Action - T_ON: 100 ns

V_LLogic Supply Not Required

TTL CMOS Input Compatible

Rail To Rail Signal Handling

RoHS

COMPLIANT

Dual Or Single Supply Operation

BENEFITS

•

Wide Dynamic Range

Low Signal Errors and Distortion

Break-Before-Make Switching Action

Simple Interfacing

The DG477 has one normally closed switch, while the

DG448 switch is normally open. They operate either from a

single + 7 V to 36 V supply or from dual 4.5 V to 20 V

supplies. They are offered in the very popular, small

T6SOP6 package.

Reduced Board Space

Improved Reliability
