GS4157-CR

GS4157/4157B Low-Voltage, 2.8Ω SPDT Analog Switch General Description Features The GS4157/4157B is a high-bandwidth, fast single-pole double-throw (SPDT) CMOS switch. It can be used as an analog switch or as a lowdelay bus switch. Specified over a wide operating power supply voltage range, 1.65V to 5.5V, the GS4157/4157B has a maximum ON resistance of 5.1-ohms at 1.65V, 3.9-ohms at 2.3V & 2.85-ohms at 4.5V. Break-beforemake switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching. ♦CMOS Technology for Bus and Analog Applications ♦ Low ON Resistance: 3-ohms @ 2.7V ♦ Wide VCC Range: 1.65V to 5.5V ♦ Rail-to-Rail Signal Range ♦ Control Input Overvoltage Tolerance: 5.5V min. ♦ High Off Isolation: 57dB at 10MHz ♦ 54dB (10MHz) Crosstalk Rejection Reduces Signal Distortion ♦ Break-Before-Make Switching ♦ High Bandwidth: 300 MHz ♦ Extended Industrial Temperature Range: –40°C to 85°C ♦ Improved Direct Replacement for NC7SB4157 ♦ Packaging (Pb-free & Green available): The control input, S, tolerates input drive signals up to 5.5V, independent of supply voltage.
