MAX3341E Datasheet, PDF (1/15 Pages) Maxim Integrated Products – ±15kV ESD-Protected USB Level Translator in UCSP with USB Detect

19-2321; Rev 0; 4/02
±15kV ESD-Protected USB Level Translator in
UCSP with USB Detect
General Description
The MAX3341E USB level translator converts logic-level
signals to USB signals, and USB signals to logic-level
signals. An internal 1.5kΩ USB termination resistor sup-
ports full-speed (12Mbps) USB operation. The
MAX3341E provides built-in ±15kV ESD-protection cir-
cuitry on the USB I/O pins, D+ and D-, and V_CC.
The MAX3341E operates with logic supply voltages as
low as 1.8V, ensuring compatibility with low-voltage
ASICs. The suspend mode lowers supply current to
less than 50µA. A unique enumerate feature allows
changes in USB communication protocol while power is
applied. The MAX3341E is fully compliant with USB
specification 1.1, and full-speed operation under USB
specification 2.0.
The MAX3341E has a USB detect that monitors the
USB bus for insertion and signals this event.
The MAX3341E is available in the miniature 4 ✕ 4
UCSP™, as well as the small 16-pin TSSOP, and is
specified over the extended temperature range, -40°C
to +85°C.
