The SN74ALVCH162827VRG4 is a high-performance, 20-bit universal bus driver from Texas Instruments, crafted with the latest technology to provide a robust interface between two buses. This integrated circuit is part of the advanced low-voltage CMOS (ALVC) family and is designed to operate with a 2.3 V to 3.6 V VCC supply voltage, making it suitable for interfacing with 3.3 V logic levels while maintaining 5 V tolerant inputs.

Key Features:

• Logic Family: ALVC - Advanced Low-Voltage CMOS
• Operating Voltage Range: 2.3 V to 3.6 V
• Bus Hold on Data Inputs: Eliminates the need for external pull-up/pull-down resistors
• Input and Output Voltage Levels: 5 V tolerant inputs and outputs
• Drive Capability: -24 mA and +24 mA on A and B ports
• Package: TVSOP (Thin Shrink Small Outline Package)
• Pin Count: 56 pins for wide connectivity options

The device features a bus-hold circuitry on its inputs, which retains the last active state without the need for an external pull-up or pull-down resistor, thus simplifying board design and reducing component count. The SN74ALVCH162827VRG4 is designed with a balanced output drive, which provides both high sink and source capability, ensuring reliable operation in a variety of applications.

Moreover, this versatile bus driver supports live insertion and withdrawal (hot plugging), which is essential for high-availability systems and eases maintenance. The I/O ports are 5 V tolerant, allowing seamless interfacing with legacy 5 V systems and providing a migration path for system voltage updates.

With its robust design and advanced features, the SN74ALVCH162827VRG4 is an excellent choice for applications that require high-speed data transfer and interfacing between different voltage domains, such as telecommunications, computing, and industrial systems. Its small footprint TVSOP package makes it an ideal solution for space-constrained applications.
