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 V
CC
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, B
0
, or B
1
) 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.
FEATURES
• Direct cross of industry standard xxx4157
• 1.65 V to 5.5 V operation voltage range
• Guaranteed 1.4 V logic high input threshold
at V
CC
= 5.5 V
• 117 MHz, - 3 dB bandwidth
• Low on-resistance
• Power down protection
• Material categorization: for definitions of compliance

Notes
a. Room = 25 °C, Full = as determined by the operating suffix.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c. Typical values are for design aid only, not guaranteed nor subject to production testing.
d. Guarantee by design, nor subjected to production test.
e. V
IN
= input voltage to perform proper function.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
