The PI74SSTV16857AEX is a high-performance, low-voltage 16-bit universal bus transceiver with 3-state outputs, designed and manufactured by Diodes Incorporated. This device is particularly suitable for facilitating bus-oriented communication in advanced computing and telecom systems where high speed, low power consumption, and minimal signal skew are crucial.

Key Features

• Bus Interface: The PI74SSTV16857AEX transceiver is equipped with two 8-bit bus transceivers with 3-state outputs that can be used independently or combined for a 16-bit bus interface.
• High-Speed Operation: With its SSTL_2 (Stub Series Terminated Logic) interface, this transceiver is optimized for high-speed data transmission, supporting bus speeds that are critical for modern high-performance systems.
• Low Voltage Operation: It operates at a nominal voltage of 2.5V, which reduces power consumption and allows for integration into low-voltage systems.
• Flow-Through Pinout: The PI74SSTV16857AEX features a flow-through architecture that minimizes the signal path and reduces noise, resulting in improved signal integrity.
• Power-Off High-Impedance: When the device is powered off, the I/O ports enter a high-impedance state, preventing potential damage to the bus system.

Applications

This transceiver is ideal for a variety of applications, including:

• High-speed memory interconnects
• Backplane data transmission
• Telecommunication switching systems
• Server and workstation bus systems
• Signal buffering and distribution
