ft3157 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 common input or output (COM).
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 bein...
