Hi-Speed USB 2.0 Switches
with ±±15k ESD
3/MAX984E
General Description
Features
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 1ꢀ5k ESD withoꢁt latchꢁp or damage. The
devices are ideal for USB 2.0 Hi-Speed applications at
480Mbps. The switches also handle all the reqꢁire-
ments for USB low- and fꢁll-speed signaling.

The MAX4983E/MAX4984E doꢁble-pole/doꢁble-throw
(DPDT) switches are fꢁlly specified to operate from a
single +2.8k to +ꢀ.ꢀk power sꢁpply and are protected
against a +ꢀ.ꢀk short to COM1 and COM2. This featꢁre
ma5es the MAX4983E/MAX4984E fꢁlly compliant with
the USB 2.0 specification of kBUS faꢁlt protection. The
devices featꢁre low-threshold-voltage logic inpꢁts, per-
mitting them to be ꢁsed with low I/O voltage systems.
The MAX4983E featꢁres an active-low enable inpꢁt
(EN) that when driven high sets the device in shꢁtdown
mode. The MAX4984E featꢁres an active-high enable
inpꢁt (EN) that when driven low sets the device in shꢁt-
down mode. When the device is in shꢁtdown mode, the
qꢁiescent sꢁpply cꢁrrent is redꢁced to 0.1µA.
