The 74AVCH20T245DGG is a 20-bit transceiver from Nexperia. It is designed for asynchronous communication between two buses. It features two 10-bit sections that can be controlled independently via their respective direction control (DIR) pins. This device is ideal for applications where high speed and low power consumption are crucial.

Applications

• Asynchronous data transfer between buses
• Level translation
• Memory interface
• Data buffering
• Signal isolation

Features

• 20-bit transceiver
• Two 10-bit sections with independent direction control
• Low propagation delay
• Low power consumption
• Overvoltage tolerant inputs
• Complies with JEDEC standard no. 8-1A

Benefits

• Enables high-speed data transfer
• Reduces power consumption in portable devices
• Simplifies system design with independent control sections
• Protects the device from overvoltage conditions
• Ensures compatibility with other logic devices

Additional Details

The 74AVCH20T245DGG operates within a supply voltage range of 1.4 V to 3.6 V. It is available in a TSSOP56 package. The device features separate supply voltage pins (VCCA and VCCB) for flexible level translation. The outputs are designed to drive terminated transmission lines. The inputs are overvoltage tolerant, allowing them to accept voltages higher than the supply voltage without damage. This feature enhances the robustness of the device in noisy environments.
