TC7WH245

      The TC7WH245 is an advanced high speed CMOS DUAL BUS TRANSCEIVER fabricated with silicon gate CMOS technology.It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.It is intended for two-way asynchronous communication between data busses.The direction of data transmission is determined by the level of the DIR input.The enable input can be used to disable the device so that the busses are effectively isolated.All inputs are equipped with protection circuits against staticdischarge.
      Features of TC7WH245 are:high speed,low power dissipation,high noise immunity,balanced propagation delays and wide operating voltage range,low noise.
      There are application notes:(1)do not apply a signal to any bus terminal when it is the output mode.Damage may result.(2)All floating bus terminals must have their input levels fixed by means of pull up or pull down resistors or bus terminator IC's such as the TC40117BP.(3)A parasitic diode is formed between the bus and VCC terminals.Therefore bus terminal can not be usrd to interface 5V to 3V systems directly.
      Maximum ratings of TC7WH245 are as follows:(1)suply voltage range is -0.5-7.0V;(2)DC input voltage is -0.5-7.0V;(3)DC output voltage is -0.5-0.5V;(4)storage temperature is -65-150.
