ET7222

Analog Switches - Special Purpose Overview

The ETEK ET7222 is a single-channel double-pole double-throw (DPDT) analog switch designed for high-speed USB 2.0 data transmission applications. It operates within a voltage range of 1.65 V to 4.5 V and features a typical on-resistance of 6.0 Ω at Vcc = 3.3 V. The device exhibits low bit-to-bit jitter of less than 50 ps, a transmission delay of approximately 250 ps, and a bandwidth exceeding 750 MHz. Crosstalk is maintained at -45 dB at 250 MHz, with a channel capacitance of 4.0 pF when conducting. Static current consumption is typically 1.0 μA. Available in QFN10L-1.8*1.4 (ET7222Y) and MSOP10 (ET7222U) packages.

Analog Switches - Special Purpose Procurement Notes

Verify the specific package suffix against official documentation, as ET7222Y denotes QFN10L and ET7222U denotes MSOP10. Confirm that the source document explicitly identifies ETEK Microelectronics as the manufacturer rather than a distributor. Ensure the datasheet revision matches the required electrical specifications for your design.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring DPDT switching for USB 2.0 differential pairs. The choice between ET7222Y and ET7222U depends on board space constraints and assembly requirements. Ensure the operating voltage remains within the 1.65 V to 4.5 V range to maintain specified performance metrics.
