鹵15kV ESD-Protected USB Level Translators in
UCSP
General Description
The MAX3340E/MAX3343E bidirectional level transla-
tors convert logic-level signals to USB signals, and USB
signals to logic-level signals. They include the 1.5k鈩?/div>
USB termination resistor internally, and support both
full-speed (12Mbps) and low-speed (1.5Mbps) USB
operation. They have built-in 鹵15kV ESD protection cir-
cuitry to guard the USB I/O pins, D+ and D-.
The MAX3340E/MAX3343E operate with V
L
at voltages
as low as 1.8V, ensuring compatibility with low-voltage
ASICs. The MAX3340E/MAX3343E feature a logic-
selectable suspend mode that lowers current draw to
less than 200碌A(chǔ). The MAX3340E/MAX3343E have a
unique re-enumerate feature that allows changes in
USB communication protocol while the power is on. The
MAX3340E/MAX3343E are fully compliant with USB
specification 1.1, and the full-speed and low-speed
operation under USB specification 2.0.
The MAX3340E/MAX3343E are available in the minia-
ture 4 x 4 chip-scale package, as well as the small 14-
pin TSSOP, and are rated for the -40擄C to +85擄C
extended temperature range.
