ON Semiconductor 74VCX16500MTD: Low Voltage 18-Bit Universal Bus Transceiver with 3.6V Tolerant Inputs and Outputs

The 74VCX16500MTD from ON Semiconductor is an advanced 18-bit universal bus transceiver designed to address the needs of high-speed, low-power consumption, and low-voltage operation in modern digital systems. This versatile component is capable of bidirectional communication and is an ideal choice for facilitating data transfer between two buses of different voltage levels, thanks to its 3.6V tolerant inputs and outputs.

Key Features

• Low Voltage Operation: The 74VCX16500MTD operates at a nominal voltage of 1.65V to 3.6V, which allows for integration into systems that require low-voltage power supplies, reducing overall power consumption.
• High-Speed Performance: With a propagation delay of just 3.9ns at 3.3V, this transceiver is suitable for high-speed applications that demand quick data transfer rates without compromising signal integrity.
• Bus-Hold Circuitry: Integrated bus-hold circuitry on the data inputs eliminates the need for external pull-up or pull-down resistors, simplifying board design and saving space.
• Power-Off High Impedance: Input and output interface circuits are designed to go into a high-impedance state when the device is powered down, thus preventing any damaging backflow current.
• 3.6V Tolerant Inputs and Outputs: The transceiver's inputs and outputs can tolerate up to 3.6V even when the device is powered down to 1.65V, ensuring compatibility with higher voltage logic levels.
• Latch-Up Performance: It exceeds 300mA of latch-up performance per JESD 78, Class II, offering robustness against latch-up events.

Applications

The 74VCX16500MTD is designed for versatile applications in computing and telecommunication where mixed-voltage systems and low power operation are essential. It is particularly useful in:

• Memory interfacing
• Data communication systems
• Server environments
• Embedded systems
• Signal bridging between different voltage domains
