It routes one common terminal to either of two independent I/O paths, functioning as a 2:1 multiplexer or 1:2 demultiplexer. ## 15 Ohm on-resistance and 300 MHz bandwidth — what they mean for signal routing The 15 Ohm max on-state resistance is low enough to minimise insertion loss in audio, video, and low-frequency analog paths, while the 300 MHz -3dB bandwidth supports high-speed digital signals like SPI, I2C, or UART without significant edge degradation. Crosstalk is rated at -54 dB at 10 MHz, which keeps channel-to-channel bleed low enough for multiplexing multiple analog channels in a data-acquisition front end. Switching times of 5.7 ns turn-on and 3.8 ns turn-off allow fast signal path reconfiguration, useful in sample-and-hold circuits or RF envelope switching. This eliminates the need to qualify a replacement for ongoing builds. The SOT-23-6 package is widely used and second-sourced across the industry, reducing single-source exposure on the BOM.","metaTitle":"74LVC1G3157DBVRE4 SPDT Analog Switch, 15 Ohm, 300 MHz","metaDescription":"74LVC1G3157DBVRE4 is an active SPDT analog switch from TI. 15 Ohm on-resistance, 300 MHz bandwidth, -54 dB crosstalk at 10 MHz.
