NAME
FUNCTION
115
VL
Digital I/O Connections Logic Supply. Connect a +1.65V to +3.6V supply to VL. Bypass VL to
GND with a 0.1F ceramic capacitor.

1
SPD
Speed-Selector Input. Connect SPD to GND to select the low-speed data rate (1.5Mbps).
Connect SPD to VL to select the full-speed data rate (12Mbps).

2
RCV
Differential-Receiver Output. RCV responds to the differential input on D+ and D- (Tables 3 and
4). RCV asserts low if SUS = VL.
43
VP
Receiver Output/Driver Input. VP functions as a receiver output when
OE = VL. VP duplicates D+
when receiving. VP functions as a driver input when
OE = GND.
54
VM
Receiver Output/Driver Input. VM functions as a receiver output when
OE = VL. VM duplicates D-
when receiving. VM functions as a driver input when
OE = GND.

N.C.
No Connection. Not internally connected.

SUS
Suspend Input. Drive SUS low for normal operation. Drive SUS high to put the MAX3450E/
MAX3451E/MAX3452E into suspend mode. RCV asserts low in suspend mode. VP and VM
remain active in suspend mode.
99
OE
Output Enable. Drive
OE to GND to enable the transmitter outputs. Drive OE to VL to disable the
transmitter outputs.
OE also controls the I/O direction of VP and VM (Tables 3 and 4).
10
D-
USB Input/Output. For
OE = GND, D- functions as a USB output, with VM providing the input signal. For
OE = VL, D- functions as a USB input, with VM functioning as a single-ended receiver output. Connect a
1.5k
Ω resistor from D- to VTRM for low-speed (1.5Mbps) operation (MAX3450E and MAX3452E).
11
D+
USB Input/Output. For
OE = GND, D+ functions as a USB output, with VP providing the input signal. For
OE = VL, D+ functions as a USB input, with VP functioning as a single-ended receiver output. Connect
a 1.5k
Ω resistor from D+ to VTRM for full-speed (12Mbps) operation (MAX3450E and MAX3452E).
12
VTRM
Internal Regulator Output. VTRM provides a regulated +3.3V output. Bypass VTRM to GND with a
1F (min) ceramic capacitor as close to the device as possible. VTRM normally derives power
from VBUS. Alternatively, drive VTRM directly with a +3.3V
±10% supply (MAX3450E and MAX3451E).
VTRM provides power to internal circuitry and provides the pullup voltage for an external USB
pullup resistor (MAX3450E and MAX3452E). Do not use VTRM to power external circuitry.
N.C.
No Connection. Not internally connected (MAX3450E).
ENUM
Enumerate Function Selection Input (MAX3451E). Drive ENUM to VL to connect the internal 1.5k
Ω
resistor between VTRM and D+ or D-, depending on the SPD state. Drive ENUM to GND to
disconnect the internal 1.5k
Ω resistor. For SPD = VL, the 1.5kΩ pullup resistor connects to D+.
For SPD = GND, the 1.5k
Ω pullup resistor connects to D-.
13
BD
Bus-Detection Output (MAX3452E). The push-pull BD output asserts low and the device enters
sharing mode if VBUS < +3.6V. BD asserts high if VBUS > +4.0V.
14
VBUS
USB Power-Supply Input. Connect a +4.0V to +5.5V power supply to VBUS. VBUS provides power
to the internal linear regulator. Bypass VBUS to GND with a 0.1F ceramic capacitor as close to
the device as possible. Connect VBUS and VTRM together when powering the MAX3450E or
MAX3451E with an external power supply (+3.3V
±10%).
