Wide VCC Range: 1.65V to 5.5V Rail-to-Rail Signal Range Control Input Overvoltage Tolerance: 5.5V min. High Off Isolation: -42dB Crosstalk Rejection Reduces Signal Distortion: -70dB Low THD (0.05% @ VCC = 2.7V) Break-Before-Make Switching Extended Industrial Temperature Range: –40°C to 85°C Packaging (Pb-free & Green): – 10-ball Chip Scale Packaging (CSP) Description Pericom Semiconductor's PI5A4684 is a dual high-bandwidth, fast single-pole double throw (SPDT) CMOS switch. It can be used as an analog switch or as a low-delay bus switch. Specified over a wide operating power supply voltage, 1.65V to 5.5V, the PI5A4684 has a maximum On-Resistance of 0.5Ω at +2.7V. Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching. The control input, INX, tolerates input drive signals up to 6.0V, independent of supply voltage.
