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.
