Part Details:

TC74LCX245F/FW/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX245F,TC74LCX245FW,TC74LCX245FT,TC74LCX245FK Low-Voltage Octal Bus Transceiver with 5-V Tolerant Inputs and Outputs The TC74LCX245F/FW/FT/FK is a high-performance CMOS Note: xxxFW (JEDEC SOP) is not available in octal bus transceiver. Designed for use in 3.3-V systems, it Japan. achieves high-speed operation while maintaining the CMOS low TC74LCX245F power dissipation. The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5-V supply environment for both inputs and outputs. The direction of data transmission is determined by the level of the DIR input. The enable input ( OE ) can be used to disable the device so that the busses are effectively isolated. All inputs are equipped with protection circuits against static discharge. Features (Note) · Low-voltage operation: VCC = 2.0 to 3.6 V · High-speed operation: tpd = 7.0 ns (max) (VCC = 3.0 to 3.6 V) · Ouput current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V) · Latch-up performance: ±500 mA · Available in JEDEC SOP, JEITA SOP and TSSOP TC74LCX245FW · Bidirectional interface between 5.0 V and 3.3 V signals · Power-down protection provided on all inputs and outputs · Pin and function compatible with the 74 series (74AC/VHC/HC/F/ALS/LS etc.) 245 type Note: Do not apply a signal to any bus pins when it is in the output mode. Damage may result. All floating (high impedance) bus pins must have their input levels fixed by means of pull-up or pull-down TC74LCX245FT resistors.
