SOTINYTM Low Voltage SPDT Analog Switch 2:1 Mux/Demux Bus Switch

CMOS Technology for Bus and Analog Applications SOTINY Package Technology: 6-pin, Thin Dual Flat in Line (TDFN) package, SC70 Package Low ON Resistance: 8 ohms at 3.0V Wide VCC Range: to 5.5V Rail-to-Rail Signal Range Control Input Overvoltage Tolerance: 5.5V min. Fast Transition Speed: 5.2ns max. at 5V High Off Isolation: 54dB (10MHz) Crosstalk Rejection Reduces Signal Distortion Break-Before-Make Switching High Bandwidth: 250 MHz Extended Industrial Temperature Range: to 85C Improved Direct Replacement for NC7SB3157


The is a high-bandwidth, fast single-pole double-throw (SPDT) CMOS switch. It can be used as an analog switch as a low-delay bus switch. Specified over a wide operating power supply voltage range, to 5.5V, the PI5A3157 has a maximum ON resistance of 12 ohms 1.65V, 9 ohms & 6 ohms at 4.5V. Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching. The control input, S, tolerates input drive signals to 5.5V, independent of supply voltage. is an improved direct replacement for the NC7SB3157.
