The SN74BCT640NSR is an advanced high-speed CMOS (Complementary Metal-Oxide-Semiconductor) octal bus transceiver from Texas Instruments, a renowned global semiconductor company.

• Design: Asynchronous two-way communication between data buses
• Features: Direction control input (DIR) and an output enable input (OE)
• DIR input High: Transmits data from the A bus to the B bus
• DIR input Low: Transmits data from the B bus to the A bus
• Control: The logic level @ the DIR input determines the direction
• Functionality: OE input can be used to disable the device so that the buses are effectively isolated
• Voltage Supply: Operates with a 5V voltage supply
• Temperature Range: Capable of handling a wide range of temperatures from -40°C to 85°C
• Design: Designed to drive heavily loaded bus lines without the need for an external resistor
• Technology: Texas Instruments’ BiCMOS technology
• Package: Available in a 20-pin NSOIC package
• Protection: Built-in ESD protection
• Compliance: RoHS compliant
