XL74HC245 – Octal Bus Transceiver – Xinluda

The XL74HC245 from Xinluda is an octal (8-bit) 3-state non-inverting bus transceiver in a SOP-20 package, enabling asynchronous bidirectional data communication between two buses with direction and output-enable control.

The XL74HC245 is an octal (8-bit) 3-state non-inverting bus transceiver manufactured by Shenzhen Xinluda Information Technology Co., Ltd (Xinluda). Part of the high-speed silicon-gate CMOS 74HC logic family, this device is designed for asynchronous two-way communication between data buses. Data flows from bus A to bus B or from bus B to bus A depending on the logic level applied to the direction control (DIR) input, while the active-low Output Enable (OE) input places all outputs in a high-impedance state to isolate the bus.

Key Features

• Octal (8-bit) bidirectional bus transceiver for asynchronous data communication
• 3-state, non-inverting outputs that drive the bus directly
• Direction control (DIR) input selects A-to-B or B-to-A data transfer
• Active-low Output Enable (OE) input isolates the bus in high-impedance mode
• PNP inputs reduce DC loading on the bus
• Input hysteresis improves noise margin
• Typical port-to-port propagation delay of approximately 8 ns
• Meets JEDEC standard No. 7A; ESD protection (HBM) exceeding 2000 V
• Operating temperature range of -40°C to +85°C
• RoHS compliant

Applications

• Microprocessor and microcontroller data-bus buffering
• Bidirectional bus interface and isolation
• Memory and peripheral I/O expansion
• Backplane and board-to-board data transfer
• Industrial control and embedded logic systems
