DESCRIPTION

The DG4157E is a high performance single-pole,

double-throw (SPDT) analog switch designed for 1.65 V to

5.5 V operation with a single power rail.?

Fabricated with high density CMOS technology, the device

achieves low on resistance of 0.86 ? at a 4.5 V power

supply, low power consumption, and fast switching speeds. ?

The DG4157E can handle both analog and digital signals

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

transmitted in either direction. Its control logic inputs can go

over V+ up to 5.5 V. The control logic input high threshold is

guaranteed as low as 1.8 V over the power supply range up

to 5.5 V. It features break before make switching

performance. Its -3 dB bandwidth is typically 152 MHz.?

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 DG4157E is available in the ultra compact μDFN-6L and

SC-70-6 packages.
