The Vishay Semiconductor DG271B high speed quad single-pole single-throw analog switch is intended for applications that require low on-resistance, low leakage currents, and fast switching speeds. The DG271B has a redesign internal regulator which improves start-up over the DG271.

Fast switching tON 55 ns
Low charge injection 5 pC
Low rDS(on) 32 Ω
Low leakage 50 pA
