The SN74ALVCHR16269GR is a high-performance, 12-bit universal bus driver from Texas Instruments, designed to address the needs of high-speed memory and data bus interface applications. This integrated circuit is part of the Advanced Low-Voltage CMOS (ALVC) family, which is renowned for its low power consumption and high data throughput capabilities.

Key Features:

• Technology: Advanced Low-Voltage CMOS (ALVC)
• Bus Interface Type: Universal 16-bit
• Output Drive: -32 mA / 64 mA
• Supply Voltage Range: 1.65 V to 3.6 V
• Operating Temperature Range: -40°C to 85°C
• Package: TSSOP (Thin Shrink Small Outline Package)

The SN74ALVCHR16269GR is optimized for 1.65 V to 3.6 V VCC operation, making it suitable for interfacing with both 3.3 V and 2.5 V logic levels, providing a bridge between different voltage domains.
