ꢀIN

NAM

FUNCTION

THIN

QFNꢄ ꢀ

TEEOꢀ

ꢁigital I/O Connections Logic Supply. Connect a +1.65V to +3.6V supply to V . Bypass V to

GNꢁ with a 0.1µF ceramic capacitor.

Speed-Selector Input. Connect SPꢁ to GNꢁ to select the low-speed data rate (1.5Mbps).

Connect SPꢁ to V to select the full-speed data rate (12Mbps).

SPꢁ

RCV

ꢁifferential-Receiver Output. RCV responds to the differential input on ꢁ+ and ꢁ- (Tables 3 and

4). RCV asserts low if SUS = V .

Receiver Output/ꢁriver Input. VP functions as a receiver output when OE = V . VP duplicates ꢁ+

when receiving. VP functions as a driver input when OE = GNꢁ.

Receiver Output/ꢁriver Input. VM functions as a receiver output when OE = V . VM duplicates ꢁ-

when receiving. VM functions as a driver input when OE = GNꢁ.

No Connection. Not internally connected.

Ground

5, 8, 16

N.C.

GNꢁ

Suspend Input. ꢁrive SUS low for normal operation. ꢁrive 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.

SUS

ꢁ-

Output Enable. ꢁrive OE to GNꢁ to enable the transmitter outputs. ꢁrive OE to V to disable the

transmitter outputs. OE also controls the I/O direction of VP and VM (Tables 3 and 4).

USB Input/Output. For OE = GNꢁ, ꢁ- functions as a USB output, with VM providing the input signal. For

OE = V , ꢁ- functions as a USB input, with VM functioning as a single-ended receiver output. Connect a

1.5ꢀΩ resistor from ꢁ- to V

for low-speed (1.5Mbps) operation (MAX3450E and MAX3452E).

TRM

USB Input/Output. For OE = GNꢁ, ꢁ+ functions as a USB output, with VP providing the input signal. For

OE = V , ꢁ+ functions as a USB input, with VP functioning as a single-ended receiver output. Connect

ꢁ+

a 1.5ꢀΩ resistor from ꢁ+ to V

for full-speed (12Mbps) operation (MAX3450E and MAX3452E).

TRM

01/MAX3452E

Internal Regulator Output. V

provides a regulated +3.3V output. Bypass V

to GNꢁ with a

TRM

1µF (min) ceramic capacitor as close to the device as possible. V

normally derives power

TRM

from V

. Alternatively, drive V

directly with a +3.3V 10% supply (MAX3450E and MAX3451E).

TRM

BUS

TRM

provides power to internal circuitry and provides the pullup voltage for an external USB

TRM

pullup resistor (MAX3450E and MAX3452E). ꢁo not use V

to power external circuitry.

TRM

N.C.

No Connection. Not internally connected (MAX3450E).

Enumerate Function Selection Input (MAX3451E). ꢁrive ENUM to V to connect the internal 1.5ꢀΩ

resistor between V

and ꢁ+ or ꢁ-, depending on the SPꢁ state. ꢁrive ENUM to GNꢁ to

TRM

ENUM

disconnect the internal 1.5ꢀΩ resistor. For SPꢁ = V , the 1.5ꢀΩ pullup resistor connects to ꢁ+.

For SPꢁ = GNꢁ, the 1.5ꢀΩ pullup resistor connects to ꢁ-.

Bus-ꢁetection Output (MAX3452E). The push-pull Bꢁ output asserts low and the device enters

Bꢁ

sharing mode if V

< +3.6V. Bꢁ asserts high if V

> +4.0V.

BUS

USB Power-Supply Input. Connect a +4.0V to +5.5V power supply to V

. V

BUS BUS

provides power

to the internal linear regulator. Bypass V

to GNꢁ with a 0.1µF ceramic capacitor as close to

together when powering the MAX3450E or

TRM

BUS

—

BUS

the device as possible. Connect V

and V

BUS

MAX3451E with an external power supply (+3.3V 10%).

Exposed Pad. Connect exposed pad to ground.
