340 MHz SPDT switch for signal routing
The Texas Instruments SN74LVC1G3157DCK3 is a single-pole double-throw (SPDT) analog switch in a 6-pin SC-70-6 package, designed for routing analog or digital signals up to 340 MHz with a 15 Ohm max on-resistance.
Bandwidth and signal integrity
The 340 MHz -3 dB bandwidth supports high-speed analog video, RF switching, and digital data paths up to LVDS rates, while the -54 dB crosstalk at 10 MHz keeps channel isolation clean for multiplexed ADC inputs or audio routing. Charge injection is rated at 7 pC typical, which matters for sample-and-hold circuits where the injected charge must settle before the next conversion cycle.
