SN74LVT162245AGQLR - Texas Instruments

The SN74LVT162245AGQLR is a high-performance, 16-bit bus transceiver from Texas Instruments, designed to provide bidirectional voltage-level translation and buffering for interfacing between systems operating at different voltage levels. This device is part of the LVT family, which is known for its low-voltage operation and tolerance to higher voltages, making it suitable for mixed-voltage systems.

Featuring 16-bit dual-supply bus transceiving, the SN74LVT162245AGQLR is capable of transferring data from the A bus to the B bus and vice versa, depending on the logic level at the direction control (DIR) input. The output enable (OE) input can be used to disable the device's outputs to allow for bus contention resolution. The device operates at a 3.3V Vcc supply voltage, while the A bus is designed to interface with 5V signals and the B bus with 3.3V signals.

Key features of the SN74LVT162245AGQLR include:

• Support for mixed-mode signal operation, allowing voltage translation between 5V and 3.3V buses.
• High drive current outputs (+64 mA/-32 mA), which are suitable for driving high-capacitive loads and ensuring signal integrity.
• Low power consumption, with a typical ICC of only 0.5 µA in the high-impedance state, contributing to energy-efficient designs.
• Control inputs (DIR, OE) compatible with TTL levels, allowing for easy integration with legacy systems.
• Flow-through architecture to simplify PCB layout.
• Support for live insertion and withdrawal (hot swapping) to minimize system downtime.

The SN74LVT162245AGQLR is available in a 48-pin LQFP (Low-Profile Quad Flat Package), which is designed to optimize board space and ensure a compact footprint. This product is ideal for applications that require reliable high-speed data transfer and voltage translation, such as data communication, computing, and industrial systems.

With its robust design and compatibility with JEDEC standards, the SN74LVT162245AGQLR from Texas Instruments represents a reliable solution for system designers looking to bridge the gap between different voltage domains while maintaining signal integrity and performance.
