參數(shù)資料

XR19L222

TWO CHANNEL INTEGRATED UART AND RS-232 TRANSCEIVER

REV. 1.0.1

NOTE: Pin type: I=Input, O=Output, I/O= Input/output, OD=Output Open Drain. For CMOS/TTL Voltage levels, ’LOW’

indicates a voltage in the range 0V to VIL and ’HIGH" indicates a voltage in the range VIH to VCC. For RS-232

Voltage levels, ’LOW’ is any voltage < 1.5V and ’HIGH’ is any voltage > 3V.

PAD

Pwr The center pad on the backside of the 64-QFN package is metallic and is not electrically

connected to anything inside the device. It must be soldered on to the PCB and may be

optionally connected to GND on the PCB. The thermal pad size on the PCB should be the

approximate size of this center pad and should be solder mask defined. The solder mask

opening should be at least 0.0025" inwards from the edge of the PCB thermal pad.

26, 28, 33,

34, 49, 50

No Connect. Note that in Motorola mode, the IOR# pin also becomes an NC pin.
