ft3157
ft3157 is Low-Ohmic Single-Pole Double-Throw Analog Switch manufactured by Fangtek.
Low-Ohmic Single-Pole Double-Throw Analog Switch
GENERAL DESCRIPTION
The ft3157 is a low on-resistance high speed single-pole dual-throw (SPDT) analog switch suitable for use as an analog or digital 2:1 multiplexer/demultiplexer. It has a digital select input (IN), two independent inputs or outputs (NO and NC) and a mon input or output (). Schmitt-trigger action at the digital input makes the circuit tolerant to slower input rise and fall times.
The ft3157 operates from a 1.65V to 5.5V power supply and Features high-bandwidth (250MHz) and low on-resistance (4Ω). It also Features a break-before-make switching to prevent disruption of signals due to both switches temporarily being enabled during switching.
The ft3157 is available in SC70-6L (2.0mm x2.1mm) package.
