TC74LCX245F

TC74LCX245F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX245F, TC74LCX245FK Low-Voltage Octal Bus Transceiver with 5-V Tolerant Inputs and Outputs The TC74LCX245 is a high-performance CMOS octal bus transceiver. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low 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 = 1.65 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 JEITA SOP, VSSOP (US) 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 TC74LCX245F TC74LCX245FK Weight SOP20-P-300-1.27A VSSOP20-P-0030-0.50 : 0.22 g ( typ.) : 0.03 g ( typ.) 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 m...
