NAME
FUNCTION
1
15
V
L
Digital I/O Connections Logic Supply. Connect a +1.65V to +3.6V supply to V
L
. Bypass V
L
to GND
with a 0.1μF ceramic capacitor.
2
1
SPD
Speed-Selector Input. Connect SPD to GND to select the low-speed data rate (1.5Mbps). Connect
SPD to V
L
to select the full-speed data rate (12Mbps).
3
2
RCV
Differential-Receiver Output. RCV responds to the differential input on D+ and D- (Tables 3 and 4).
RCV asserts low if SUS = V
L
.

3
VP
Receiver Output/Driver Input. VP functions as a receiver output when
OE
= V
L
. VP duplicates D+
when receiving. VP functions as a driver input when
OE
= GND.
5
4
VM
Receiver Output/Driver Input. VM functions as a receiver output when
OE
= V
L
. 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.

9
OE
Output Enable. Drive
OE
to GND to enable the transmitter outputs. Drive
OE
to V
L
to disable the
transmitter outputs.
OE
also controls the I/O direction of VP and VM (Tables 3 and 4).

V
TRM
Internal Regulator Output. V
TRM
provides a regulated +3.3V output. Bypass V
TRM
to GND with a 1μF
(min) ceramic capacitor as close to the device as possible. V
TRM
normally derives power from
V
BUS
. Alternatively, drive V
TRM
directly with a +3.3V
±
10% supply (MAX3450E and MAX3451E).
V
TRM
provides power to internal circuitry and provides the pullup voltage for an external USB pullup
resistor (MAX3450E and MAX3452E). Do not use V
TRM
to power external circuitry.
N.C.
No Connection. Not internally connected (MAX3450E).
ENUM
Enumerate Function Selection Input (MAX3451E). Drive ENUM to V
L
to connect the internal 1.5k
resistor between V
TRM
and D+ or D-, depending on the SPD state. Drive ENUM to GND to
disconnect the internal 1.5k
resistor. For SPD = V
L
, the 1.5k
pullup resistor connects to D+.
For SPD = GND, the 1.5k
pullup resistor connects to D-.
13
13
BD
Bus-Detection Output (MAX3452E). The push-pull BD output asserts low and the device enters
sharing mode if V
BUS
< +3.6V. BD asserts high if V
BUS
> +4.0V.
14
14
V
BUS
USB Power-Supply Input. Connect a +4.0V to +5.5V power supply to V
BUS
. V
BUS
provides power to
the internal linear regulator. Bypass V
BUS
to GND with a 0.1μF ceramic capacitor as close to the
device as possible. Connect V
BUS
and V
TRM
together when powering the MAX3450E or MAX3451E
with an external power supply (+3.3V
±
10%).
