The MAX3453E–MAX3456E USB-compliant transceivers
convert single-ended or differential logic-level signals to
USB signals, and USB signals to single-ended or differ-
ential logic-level signals. The MAX3453E fully complies
with full-speed (12Mbps) operation under USB specifica-
tion 2.0. The MAX3454E–MAX3456E fully comply with
USB specification 1.1, and full-speed (12Mbps) and low-
speed (1.5Mbps) operation under USB specification 2.0.
The MAX3453E–MAX3456E operate with V
+1.65V, ensuring compatibility with low-voltage ASICs.
The MAX3453E–MAX3456E derive power from the USB
host (V

The MAX3453E–MAX3456E meet the physical layer
specifications for logic-level supply voltages (V
+1.65V to +3.6V. Integrated ±15kV ESD protection safe-
guards the D+ and D- USB I/O ports.
The MAX3453E/MAX3454E feature an enumerate func-
tion providing an internal 1.5kΩ pullup resistor from D+
(MAX3453E/MAX3454E) or D- (MAX3454E only) to
