It can be used as an analog switch or as a low-delay bus switch. Specified over a wide operating power supply voltage range, 1.65V to 5.5V, the PI5A3157 has a maximum ON resistance of 12 ohms at 1.65V, 9 ohms at 2.3V & 6 ohms at 4.5V. CMOS Technology for Bus and Analog Applications SOTINY Package Technology: 6-pin, SC70 Package Low ON Resistance: 8 ohms at 3.0V Wide VCC Range: 1.65V 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: 57dB at 10MHz 54dB (10MHz) Crosstalk Rejection Reduces Signal Distortion Break-Before-Make Switching High Bandwidth: 250 MHz Extended Industrial Temperature Range: 40°C to 85°C Improved Direct Replacement for NC7SB3157 Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching. The control input, S, tolerates input drive signals up to 5.5V, independent of supply voltage. PI5A3157 is an improved direct replacement for the NC7SB3157.
