ИС переключателей USB MAX4984EEVB+

Аналоговый переключатель , 2 канал(-ов), DPDT, 10 Ом, 2.8В до 5.5В, µTQFN, 10 вывод(-ов)

The MAX4984EEVB+ is a hi-speed USB 2.0 DPDT switch with ±15V ESD protection in 10 pin µTQFN package. This analogue switch combines low on-capacitance and low on-resistance necessary for high performance switching applications. COM1 and COM2 pins are protected against ±15KV ESD (±15KV human body model, ±15KV IEC 61000-4-2 air gap and ±8KV IEC 61000-4-2 contact) without latch-up or damage. The device is ideal for USB 2.0 hi-speed applications at 480Mbps. The switch also handles all the requirements for USB low and full speed signalling. The MAX4984E is fully specified to operate from single 2.8V to 5.5V power supply and it is protected against 5.5V short to COM1 and COM2. This feature makes the device fully compliant with USB 2.0 specification of VBUS fault protection. It has low threshold voltage logic inputs which permits the device to be used with low I/O voltage systems. The MAX4984E features an active-high enable input that when driven high, sets the device in shutdown mode.
