DESCRIPTION

The DG3157E is a high speed single-pole double-throw

analog switch designed for +1.65 V to +5.5 V single power

rail operation.?

Fabricated with high density CMOS technology, the

DG3157E achieves low on-resistance, fast switching speed,

and high bandwidth while maintains low power

consumption.?

The DG3157E can handle both analog and digital signals

and permits signals with amplitudes of up to V+ to be

transmitted in either direction.?

When the select pin is low, B0 is connected to the output A

pin. When the select pin is high, B1 is connected to the

output A pin. The path that is open will have a high

impedance state with respect to the output. Break before

make switching performance is guaranteed. ?

A powered-off protection circuit is built into the switch to

prevent an abnormal current flow from COM pin to V+ during

the power-down condition. Each output pin can withstand

greater than 7 kV (human body model). ?

Operation temperature is specified from -40 °C to +85 °C.

The DG3157E is available in the compact SC-70-6L

package.
