NMFAAAA

NMFAAAA Product Preview 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 This document contains information on a product under development.
