USB Clamps, RS232 and
General Purpose Data Line
Filters with ESD Protection;
Optional Internal Switch
http://onsemi.com
USB line clamps (DOUT+, DOUT−) protect low operating voltage
loads. Five additional low pass filters are built in to reject RF noise and
EMI on RS232 and GP data lines. When the USB lines are used, a
switch is utilized to open the RS232 lines in order to reduce the
loading on the USB lines. There are two options available for this
device. NMFAAAA−1 has the switch external, and NMFAAAA−2
integrates the switch on chip. Also, when the switch is integrated, the
USB line resistors are integrated as well.
Features
• ESD Protection IEC 61000−4−2 Level 4 (Input Lines)
• ESD Protection IEC 61000−4−2 Level 1 (All I/O)
• RF Filtering (800 MHz–4.0 GHz): −30 dB Low Pass Filter (RS232
and General Purpose Data Lines)
• Input Voltage up to 5.25 V (USB Lines) and 6.0 V (RS232 and
General Purpose Data Lines)
• Max Output Voltage: TBD by Customer (RS232 and GP Data Lines)
and TBD by Customer (USB Lines)
• USB Minimum Input Signal Level: −1.0 V
• USB Line Capable of Withstanding Exposure to Burst (60 ns at
4.6 V)
• Optional Integrated Switch to Open the RS232 Lines
(NMFAAAA−2)
• 25 Bump Flip−Chip Direct Chip Attach: 2.5 mm x 2.5 mm x
0.65 mm
• This is a Pb−Free Device
Typical Application
• Cellular Phones
• Portable Equipment
