28 / 61 page ![]() Copyright © Future Technology Devices International Limited 28 FT260 HID-CLASS USB TO UART/I2C BRIDGE IC Version 1.1 Document No.: FT_001272 Clearance No.: FTDI#484 6 Devices Characteristics and Ratings 6.1 Absolute Maximum Ratings The absolute maximum ratings for the FT260 devices are as follows. These are in accordance with the Absolute Maximum Rating System (IEC 60134). Exceeding these may cause permanent damage to the device. Parameter Value Unit Conditions Storage Temperature -65°C to 150°C Degrees C Floor Life (Out of Bag) At Factory Ambient (30°C / 60% Relative Humidity) 168 Hours (IPC/JEDEC J- STD-033A MSL Level 3 Compliant)* Hours Ambient Operating Temperature (Power Applied) -40°C to 85°C Degrees C MTTF FT260 TBD Hours VCCIN Supply Voltage -0.3 to +5.5 V VCCIO IO Voltage -0.3 to +4.0 V FSOURCE Supply Voltage 3.8±0.4 V DC Input Voltage – USBDP and USBDM -0.5 to +3.63 V DC Input Voltage – High Impedance Bi-directional (powered from VCCIO) -0.3 to +(VCCIO+0.5V) V DC Output Voltage 3.3±0.15 V VOUT3V3 DC Output Current – Outputs 100 ** mA Table 6.1 Absolute Maximum Ratings * If devices are stored out of the packaging beyond this time limit the devices should be baked before use. The devices should be ramped up to a temperature of +125°C and baked for up to 17 hours. ** This DC output current on VOUT3V3 is also the power supply source for FT260 operation. If it must be the source for other components in the system, it can only supply 75mA or less. 6.2 ESD and Latch-up Specifications Description Specification Human Body Mode (HBM) > ± 2kV Machine mode (MM) > ± 200V Charged Device Mode (CDM) > ± 500V Latch-up > ± 200mA Table 6.2 ESD and Latch-Up Specifications |
