XD74HC245 – Octal Bus Transceiver – Xinluda

The Xinluda XD74HC245 is an octal (8-bit) 3-state non-inverting bus transceiver in a DIP-20 package, providing bidirectional data flow between two buses with direction and output-enable control.

The XD74HC245 from Xinluda is a high-speed silicon-gate CMOS octal (8-bit) bus transceiver with 3-state outputs, designed for asynchronous bidirectional communication between two data buses. It belongs to the industry-standard 74HC245 logic family and is supplied in a through-hole DIP-20 package (the related XL74HC245 variant uses an SOP-20 surface-mount package).

Data direction is controlled by the Direction (DIR) pin, while the Output Enable (OE) pin places all I/O lines in a high-impedance OFF state when a HIGH level is applied, allowing the device to be isolated from the bus. The part complies with JEDEC standard No. 7A.

Key Features

• Octal (8-bit) non-inverting bus transceiver with 3-state outputs
• Bidirectional A-to-B / B-to-A data flow set by the Direction (DIR) input
• Output Enable (OE) for high-impedance bus isolation
• Wide supply voltage range: 2.0 V to 6.0 V
• Operating temperature range: -40 C to +85 C
• Compliant with JEDEC standard No. 7A
• DIP-20 through-hole package (XD suffix); SOP-20 available as XL74HC245
• RoHS compliant

Applications

• Bidirectional bus buffering and isolation between microcontrollers and peripherals
• Memory and address/data bus expansion
• Backplane and board-to-board interface drivers
• Industrial control and instrumentation logic
• Level/bus interfacing in consumer and embedded electronics

Why Source XD74HC245 from Pacific Component Xchange
