TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic 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 oth 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 JEITA SOP, TSSOP and 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
