RCV
O
Receive data. CMOS level output for USB differential input
2
OE#
I
Output Enable. Active LOW, enables the transceiver to transmit data on the bus.
When not active the transceiver is in receive mode
1
MODE
I
Mode. When left unconnected, a weak pull-up transistor pulls it to VCC and in this
mode, the PDIUSBP11A is backward compatible to PDIUSBP11. When connected to
GND, the VMO/FSEO pin takes the function of FSEO (Force SEO).
Inputs to differential driver. (Outputs from SIE).

Gated version of D– and D+. Outputs are logic “0” and logic “1”. Used to detect single
ended zero (SE0#), error conditions, and interconnect speed. (Inputs to SIE).

AI/O
Data+, Data–. Differential data bus conforming to the Universal Serial Bus standard.

SUSPND
I
Suspend. Enables a low power state while the USB bus is inactive. While the suspnd
pin is active it will drive the RCV pin to a logic “0” state. Both D+ and D– are tri-stated.
9
SPEED
I
Edge rate control. Logic “1” operates at edge rates for “full speed”. Logic “0” operates
edge rates for “l(fā)ow speed”.
