M74HCT245 is an advanced high-speed CMOS OCTAL BUS TRANSCEIVER (3-STATE)
The M74HCT245 is an advanced high-speed CMOS octal bus transceiver fabricated with silicon gate C2MOS technology. It is designed for two-way asynchronous communication between data buses, with the direction of data transmission determined by the DIR input. The device includes protection circuits against static discharge and transient excess voltage on all inputs.
