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 Ω 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.
