Product details

Single analog switch for signal routing

The Texas Instruments SN74LVC1G66DBVRG4 is a single-pole single-throw (SPST) analog switch in a SOT-23-5 package. It routes one analog or digital signal path with a maximum on-resistance of 10 Ohm and a -3 dB bandwidth of 300 MHz, making it suitable for audio, video, and RF switching up to several hundred megahertz.

The 10 Ohm max on-resistance sets the insertion loss floor: at 50 Ohm system impedance the switch adds about 0.8 dB loss. The 300 MHz bandwidth means the switch passes signals up to that frequency with minimal roll-off — useful for composite video or baseband RF paths. Switching times of 4.2 ns (ton) and 5 ns (toff) allow the part to handle fast multiplexing in data-acquisition or test-equipment front ends without introducing timing skew.

Frequently asked questions

What is the on-resistance of SN74LVC1G66DBVRG4?

The maximum on-resistance is 10 Ohm. This value is specified at the rated supply voltage and temperature; actual on-resistance will be lower at higher supply voltages and higher at elevated temperatures.

What is the bandwidth of SN74LVC1G66DBVRG4?

The -3 dB bandwidth is 300 MHz. This defines the frequency at which the output signal amplitude drops by half relative to the input — adequate for analog video signals up to 1080p and baseband RF up to VHF.

Is SN74LVC1G66DBVRG4 RoHS compliant?

Texas Instruments typically marks RoHS compliance on the reel label; confirm with the supplier at quote time.
