Texas Instruments SN74ALVTHR16245 2.5-V/3.3-V 16-Bit Bus Transceiver With 3-State Outputs SN74ALVTHR16245GR

The SN74ALVTHR16245GR is a 16-bit bus transceiver designed for operation at 2.5-V and 3.3-V supply voltages, with the capability to interface with 5-V systems. It features three-state outputs and supports mixed-mode signal operation, allowing for flexibility in various applications. The device can function as two 8-bit transceivers or one 16-bit transceiver, enabling data transmission between two buses based on the direction-control input. This transceiver includes active bus-hold circuitry to maintain valid logic levels on unused inputs, eliminating the need for external pull-up or pull-down resistors. It is designed for high-speed performance, with output drive capabilities of ±12 mA at 3.3 V, and incorporates equivalent 30-,Ѷ series resistors to minimize signal overshoot and undershoot. The device also supports hot insertion with Ioff and power-up three-state features, preventing backflow current during power-down conditions. The SN74ALVTHR16245GR is specified for operation over a temperature range of -40°C to 85°C and offers robust ESD protection, exceeding standards for human-body and charged-device models. Its flow-through architecture simplifies PCB layout, making it suitable for high-density applications.
