TC74HC245AP(F)

TC74HC245AP(F) is a high speed cmos octal bus transceiver fabricated with silicon gate C²MOS technology. This achieves the high speed operation similar to equivalent LSTTL 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 (active low G) can be used to disable the device so that the busses are effectively isolated. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
