DG4157
Vishay Siliconix
Low Voltage, 1-Ω Single SPDT Analog Switch (1:2 Multiplexer) with
Power Down Protection
DESCRIPTION
The DG4157 is a high performance single pole double throw
analog switch designed for 1.65 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 VCC to be transmitted in
either direction.
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.
