SM74HC245D CMOS OCTAL BUS TRANSCEIVER (SOIC-20) IC

SM74HC245D CMOS OCTAL BUS TRANSCEIVER (SOIC-20) IC

The SM74HC245D is high speed CMOS OCTAL BUS TRANSCEIVERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. They are 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 (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.
