SN74CBT3126DBR TI Bus Switch | 14-SSOP | 4-Bit, 5V

Product Overview

The SN74CBT3126DBR from Texas Instruments is a high-performance 4-bit bus switch designed for fast and efficient signal routing in digital systems. It features four independent single-pole single-throw (SPST) switches with low on-state resistance (5 Ω typical) and wide operating voltage range (4 V to 5.5 V). Housed in a compact 14-SSOP package, this device is ideal for bus isolation, level translation, and hot-swap applications.

Detailed Technical Specifications

Key Features

• Low on-state resistance (5 Ω) minimizes signal distortion
• High bandwidth (200 MHz) supports high-speed data signals
• Ultra-low propagation delay (0.25 ns) for timing-critical paths
• Wide supply voltage range (4 V to 5.5 V) compatible with TTL/CMOS levels
• Flow-through pinout simplifies PCB layout
• ESD protection exceeds 2000 V per MIL-STD-883

Target Applications

• 5G Base Station: Signal routing between baseband processors and RF transceivers (e.g., TI TMS320C6678 DSP)
• Automotive Dashboard: Bus isolation for infotainment modules (e.g., NXP i.MX8 processor)
