Description
The DIO3749 is a low-power, SPDT high-speed
analog switch. It handles bidirectional signal flow
optimized for switching a high-speed source and
features super low off state leakage.
The DIO3749 has a high channel-to-channel noise
isolation and allows bit-to-bit skew which allows it to
pass high-speed differential signals with good signal
integrity. The low leakage current is also suitable for
TIA (Trans-impedance Amplifier) in telecom sets.
The DIO3749 contains special circuitry on the D pin,
which can tolerate up to 5.5 V when the signal level is
higher than 5 V.
The DIO3749 is available in a Green package:
SC70-6.
