SN74ALVCH162245GR Description

The SN74ALVTH162245GR from Texas Instruments is a high-performance, 16-bit (dual 8-bit) non-inverting bus transceiver designed for 2.5V/3.3V mixed-voltage systems. Operating within a 2.3V to 3.6V supply range, it integrates advanced bus-hold circuitry, eliminating the need for external pull-up/pull-down resistors. This ROHS3-compliant device is packaged in a 48-pin TSSOP (Tape & Reel) format, making it suitable for automated assembly. Though marked as Obsolete, it remains relevant for legacy designs requiring robust signal integrity in high-speed data transmission.

SN74ALVTH162245GR Features

• Dual-Supply Operation: Supports 2.3V–2.7V and 3V–3.6V voltage ranges, enabling seamless interfacing between mixed-voltage systems.
• High Drive Strength: Delivers 12mA (at 2.5V) or 32mA (at 3.3V) output current, ensuring reliable signal integrity in heavily loaded buses.
• Bus-Hold Technology: Retains data signals without external resistors, reducing BOM complexity.
• Low Power Consumption: Optimized for 3.3V ALVT (Advanced Low-Voltage Technology) with minimal static power dissipation.
• Robust ESD Protection: Exceeds 2000V HBM (Human Body Model) for enhanced reliability.
• Surface-Mount Design: MSL 1 (Unlimited) rating ensures compatibility with standard reflow processes.

SN74ALVTH162245GR Applications

• Telecommunications: Ideal for backplane drivers and line interface modules due to its high noise immunity.
• Networking Equipment: Used in routers/switches for level translation between 2.5V and 3.3V logic domains.
• Industrial Automation: Suitable for PLC I/O modules requiring bidirectional data buffering.
• Legacy Systems Maintenance: Supports upgrades of older designs needing 3.3V-tolerant buses.

Conclusion of SN74ALVTH162245GR

The SN74ALVTH162245GR excels in mixed-voltage environments with its high drive strength, integrated bus-hold, and ESD robustness. While obsolete, its low-power ALVT technology and TSSOP packaging make it a pragmatic choice for sustaining legacy systems or mitigating redesign risks. Engineers valuing signal integrity and simplified board layout will find this transceiver a reliable solution for bridging voltage domains in communication and industrial applications.
