General Description
The MAX3344E/MAX3345E USB transceivers convert
logic-level signals to USB signals, and USB signals to
logic-level signals. An internal 1.5k USB pullup resistor
supports full-speed (12Mbps) USB operation. The
MAX3344E/MAX3345E provide built-in ±15kV ESD-pro-
tection circuitry on the USB I/O pins, D+ and D-, and VCC.
The MAX3344E/MAX3345E operate with logic supply
voltages as low as 1.65V, ensuring compatibility with
low-voltage ASICs. The suspend mode lowers supply
current to less than 40A. An enumerate function allows
devices to logically disconnect while plugged in. The
MAX3344E/MAX3345E are fully compliant with USB
specification 1.1, and full-speed operation under USB
specification 2.0.
The MAX3344E/MAX3345E have a USB detect that mon-
itors the USB bus for insertion and signals this event. The
MAX3344E USB_DET threshold is between 3.6V (min)
and 4V (max), while the MAX3345E USB_DET threshold
is between 1V (min) and 2.8V (max).
The MAX3344E/MAX3345E are available in the miniature
4 4 UCSP, as well as the small 16-pin TSSOP, and
are specified over the extended temperature range,
-40°C to +85°C.
