TS3L301DGGR

Overview

The TS3L301DGGR is a 16-bit to 8-bit single-pole double-throw (SPDT) gigabit LAN switch manufactured by Texas Instruments. It integrates eight independent SPDT switches within a single package, designed for high-speed data routing in network applications. The device operates with a supply voltage range of 2.7 V to 3.6 V and features a low power consumption profile with a maximum supply current of 250 µA. It provides a bandwidth of 900 MHz and maintains an on-state resistance of 8 Ω maximum. The component supports an operating temperature range from -40°C to +85°C and is housed in a 48-pin Thin-Shrink Small Outline Package (TSSOP).

Feature Summary

• Integrates eight independent SPDT switches for efficient signal routing.
• Provides low and flat on-state resistance for consistent signal integrity.
• Supports gigabit LAN switching speeds with 900 MHz bandwidth.
• Operates within a standard 3.3 V logic supply voltage range.

Applications

• Gigabit Ethernet network infrastructure routing
• High-speed data bus switching systems
• Telecommunications equipment signal path management

Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and environmental compliance. Ensure the procurement channel sources components directly from authorized distributors or verified manufacturers to prevent counterfeit parts. Confirm RoHS and lead-free status requirements match the project specifications before finalizing orders.

Selection Notes

Select this component when designing circuits requiring multiple SPDT switching functions in a compact footprint. The 48-pin TSSOP package offers surface-mount convenience for high-density PCB layouts. Consider the 900 MHz bandwidth and 8 Ω on-resistance characteristics to ensure compatibility with gigabit data rates and signal loss requirements in the target application environment.

Part Context

The TS3L301DGGR belongs to the TS3L301 series of analog switches from Texas Instruments. This series is engineered specifically for gigabit LAN applications, offering integrated solutions that replace discrete switching components. The DGGR suffix indicates the specific 48-pin TSSOP package variant with tape and reel packaging for automated assembly processes.

Replacement Considerations

The TS3L301DGGRE4 and TS3L301DGGRG4 are confirmed equivalent part numbers within the same family. These variants maintain identical electrical specifications and pinouts, differing primarily in manufacturing lot codes or minor environmental compliance markings as defined by the manufacturer's revision history.
