SN74ALB16245DGGR Description

The SN74ALB16245DGGR is a high-performance, 16-bit bus transceiver from Texas Instruments' 74ALB series, designed for 3V to 3.6V voltage operation. This non-inverting transceiver integrates two 8-bit elements, enabling bidirectional data flow between buses. Packaged in a 48-pin TSSOP with tape-and-reel (TR) delivery, it is optimized for surface-mount applications. Although marked as obsolete, it remains compliant with ROHS3 and REACH environmental standards, making it suitable for legacy designs requiring reliable signal buffering and level translation.

SN74ALB16245DGGR Features

• Bidirectional 16-Bit Interface: Two independent 8-bit channels for flexible data routing.
• 3.3V Operation: Optimized for 3V–3.6V systems, reducing power consumption in low-voltage designs.
• High Drive Strength: 25mA output current (high/low) ensures robust signal integrity in noisy environments.
• Surface-Mount Ready: 48-TSSOP package with MSL1 (Unlimited) moisture sensitivity, ideal for automated assembly.
• Compliance: Meets EAR99, ROHS3, and REACH standards for global deployment.

SN74ALB16245DGGR Applications

• Bus Isolation/Translation: Ideal for 3.3V systems interfacing with mixed-voltage peripherals.
• Data Communication: Used in networking equipment and telecom infrastructure for signal buffering.
• Embedded Systems: Suitable for industrial controllers and automotive electronics requiring bidirectional data transfer.
• Legacy Upgrades: Replaces older transceivers in retrofit designs due to its high noise immunity and low skew.

Conclusion of SN74ALB16245DGGR

The SN74ALB16245DGGR offers a robust solution for bidirectional bus communication in 3.3V systems, combining high drive capability with compact packaging. While obsolete, its low-power operation, compliance with environmental standards, and reliability make it a pragmatic choice for legacy or cost-sensitive applications. Engineers should evaluate alternative active models for new designs but can leverage this IC for long-lifecycle projects requiring proven performance.
