SN74LVC16T245GQLR

SN74LVC16T245GQLR Description

The SN74LVC16T245GQLR from Texas Instruments is a high-performance, bidirectional voltage-level translation transceiver designed for mixed-voltage applications. This 16-bit (2 x 8-bit) device operates across a wide supply voltage range of 1.65V to 5.5V, making it versatile for interfacing between low-voltage and higher-voltage systems. Packaged in a 56-pin BGA (Tape & Reel), it is optimized for space-constrained, high-density PCB designs. Although marked as Obsolete, it remains a reliable choice for legacy systems requiring robust signal translation with 32mA output drive strength in both high and low states.

SN74LVC16T245GQLR Features

• Bidirectional Voltage Translation: Seamlessly bridges 1.8V, 2.5V, 3.3V, and 5V logic levels.
• High Drive Capability: Delivers ±32mA output current, ensuring strong signal integrity in noisy environments.
• Low Power Consumption: Leverages Texas Instruments' 74LVC series technology for efficient power management.
• Robust Packaging: 56-BGA offers superior thermal and mechanical performance for industrial applications.
• Wide Operating Range: Supports 1.65V–5.5V supply voltages, ideal for mixed-voltage systems.
• REACH Unaffected: Compliant with environmental regulations, suitable for global markets.

SN74LVC16T245GQLR Applications

• Industrial Automation: Interfaces between microcontrollers (1.8V/3.3V) and legacy 5V sensors/actuators.
• Consumer Electronics: Level-shifting in portable devices with mixed-voltage peripherals (e.g., displays, memory).
• Communications Equipment: Bidirectional data bus translation in routers/switches with multi-voltage ICs.
• Automotive Systems: Signal conditioning in infotainment or control modules (note: not AEC-Q100 qualified).

Conclusion of SN74LVC16T245GQLR

The SN74LVC16T245GQLR excels in bidirectional voltage translation with high drive strength and broad voltage compatibility. While obsolete, its 56-BGA package and 74LVC-series reliability make it a pragmatic choice for legacy designs or cost-sensitive projects requiring robust level-shifting. Engineers should evaluate newer alternatives for forward-looking designs but can rely on this IC for proven performance in industrial, consumer, and communication systems.
