It handles one channel with a break-before-make switching action, making it suitable for audio path selection, signal multiplexing, and general-purpose signal gating in industrial and consumer equipment. ## 15 Ohm on-resistance and 300 MHz bandwidth The 15 Ohm maximum on-state resistance sets the insertion loss floor for the signal path — at 10 mA load current the voltage drop is 150 mV, which matters for low-voltage analog signals. The 300 MHz -3dB bandwidth means the switch passes high-speed digital clocks and video signals up to the UHF band without significant roll-off. Channel-to-channel on-resistance matching is held to 100 mOhm, so the two signal paths present nearly identical impedance — important for maintaining balanced signal levels in stereo audio or differential routing. The control logic input thresholds track the supply rail, so the switch can be driven by the same voltage domain as the upstream controller or FPGA. ## Industrial temperature grade and SC-70-6 footprint The SC-70-6 package (SOT-363 footprint) occupies roughly 2.0 mm × 2.1 mm of board area — a compact fit for space-constrained designs like handheld instruments or IoT edge nodes.","metaTitle":"74LVC1G3157DCKRG4 SPDT Analog Switch, 15 Ohm, 300 MHz","metaDescription":"Texas Instruments 74LVC1G3157DCKRG4 single SPDT analog switch, 15 Ohm on-state resistance, 300 MHz bandwidth, 1.65 V to 5.5 V supply.
