The MAX4983E/MAX4984E are high ESD-protected analog switches that combine the low on-capacitance and low on-resistance necessary for high-performance switching applications. COM1 and COM2 are protected against ±15kV ESD without latchup or damage. The devices are ideal for USB 2.0 Hi-Speed applications at 480Mbps. The switches also handle all the requirements for USB low- and full-speed signaling. The MAX4983E/MAX4984E double-pole/double-throw (DPDT) switches are fully specified to operate from a single +2.8V to +5.5V power supply and are protected against a +5.5V short to COM1 and COM2. This feature makes the MAX4983E/MAX4984E fully compliant with the USB 2.0 specification of VBUS fault protection. The devices feature low-threshold-voltage logic inputs, permitting them to be used with low I/O voltage systems. The MAX4983E features an active-low enable input (EN) that when driven high sets the device in shutdown mode. The MAX4984E features an active-high enable input (EN) that when driven low sets the device in shutdown mode. When the device is in shutdown mode, the quiescent supply current is reduced to 0.1µA. The MAX4983E/MAX4984E are available in a space-saving, 10-pin, 1.4mm x 1.8mm UTQFN package, and operate over a -40°C to +85°C temperature range.
The MAX4983E and MAX4984E are high‑ESD‑protected DPDT analog switches designed for USB 2.0 Hi‑Speed (480 Mbps) applications. They operate from a single +2.8 V to +5.5 V supply and feature low‑threshold logic inputs compatible with 1.4 V logic levels.
Key features include ±15 kV ESD protection on COM pins, low on‑resistance (≈5 Ω typ), 950 MHz -3 dB bandwidth, and a shutdown mode that reduces quiescent current to 0.1 µA. The devices are offered in a 10‑pin 1.4 mm × 1.8 mm UTQFN package and operate over –40 °C to +85 °C.
| Supply Voltage Range | +2.8 V to +5.5 V |
|---|---|
| On‑Resistance (typ) | 5 Ω |
| -3 dB Bandwidth (typ) | 950 MHz |
| Enable Input Type | Active‑Low for MAX4983E, Active‑High for MAX4984E |
| Shutdown Quiescent Current | 0.1 µA |
| Package | 10‑pin 1.4 mm × 1.8 mm UTQFN |
| Operating Temperature Range | -40 °C to +85 °C |
They operate from +2.8 V up to +5.5 V.
In shutdown mode the quiescent supply current is reduced to 0.1 µA.
The typical on‑resistance is about 5 Ω.
The devices provide ±15 kV ESD protection on COM pins (Human Body Model) and additional IEC 61000‑4‑2 protection.
