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 |
| Description & Applications |
东芝CMOS数字集成电路硅单片 低电压与5-V宽容输入和输出的八路总线收发器 TC74LCX245是一个高性能CMOS八进制总线 收发器。 3.3-V系统中使用的设计，它实现了 高速运转，同时保持低功耗的CMOS。 该设备是专为低电压（3.3 V）VCC应用， 但它可以用于连接到5-V电源环境下超视距的输入和输出。 的数据传输方向的DIR输入由电平确定。使能输入（OE）可以用来禁用设备， 以便有效地隔离总线。 所有输入都配有保护电路防止静电放电。 功能（注） ?低电压工作：VCC= 2.0?3.6 V ?高速操作：TPD =7.0纳秒（最大值）（VCC=3.0?3.6 V） ?输出电流：IOH/ IOL= 24 mA（分钟）（VCC=3.0 V） ?闭锁性能：-500毫安 ?JEITA SOP，TSSOP和VSSOP（美国） ?5.0 V和3.3 V信号之间的双向接口 ?掉电保护提供所有输入和输出 ?引脚和功能兼容74系列 （74AC/VHC/HC/F/ALS/LS等）245型 |
