The MAX13342E/MAX13345E USB-compliant trans-
ceivers are designed to minimize the area and external
components required to interface low-voltage ASICs to
USB. The devices comply with USB 2.0 specification for
full-speed-only (12Mbps) operation. The transceivers
include an internal 3.3V regulator, an internal 1.5kΩ D+
pullup resistor, and built-in ±15kV ESD protection cir-
cuitry to protect the USB I/0 ports (D+,D-). The
MAX13345E also has internal series resistors, allowing
it to be wired directly to a USB connector.
These devices operate with logic-supply voltages as
low as +2.3V, ensuring compatibility with low-voltage
ASICs. A low-power mode reduces current consump-
tion to less than 45µA. An enumerate function controls
the D+ pullup resistor, allowing devices to logically dis-
connect while remaining plugged in.
The MAX13342E has controlled output impedance of
2Ω (max) on D+/D-, allowing the use of external switch-
es to multiplex two different USB devices onto a single
USB connector. The MAX13345E has 43.5Ω (max)
internal resistors on D+/D- for direct connection to the
USB connector.
The MAX13342E/MAX13345E are equipped with DAT
and SE0 interface signals. These transceivers provide a
USB detection function that monitors the presence of
USB V
These devices operate over the extended -40°C to +85°C
temperature range and are available in UCSP™ 2.0mm x
1.5mm and 14-pin TDFN (3mm x 3mm) packages.
