Low Voltage, 1-Ω Single SPDT Analog Switch (1:2 Multiplexer) with

Power Down Protection

DESCRIPTION

FEATURES

The DG4157 is a high performance single pole double throw

analog switch designed for 1.8 V to 5.5 V operation with

single power rail.

Fabricated with high density CMOS technology, the device

achieves low on resistance as 1 Ω at 4.5 V power supply and

fast switching speed. The - 3 dB bandwidth is typically

117 MHz.

The DG4157 features break before make switch

performance, and guarantees logic HIGH control input

threshold as low as 1.4 V over the range up to 5.5 V.

It can handle both analog and digital signals and permits

signals with amplitudes of up to V_CCto be transmitted in

either direction.

Power down protection

Power down protection circuit is built in to prevent abnormal

current path through signal pins during power down

condition.

Each output pin (A, B₀, or B₁) can withstand greater than

8 kV (human body model).

It is available in both SC-70-6 and miniQFN6 packages.

The features make it an ideal part for the switching of audio,

video, and data stream.
