The Texas Instruments 74CB3Q3257DGVRE4 is a high-performance, low-voltage quad 2:1 multiplexer/demultiplexer bus switch designed for the switching of high-speed digital signals. This device is part of Texas Instruments' 74CB series, known for its robust build and reliability in various applications.

Key Features

• Wide Operating Voltage Range: The device operates at a voltage range of 2.3V to 3.6V, making it suitable for interfacing with low-voltage logic without the need for level shifting.
• High Bandwidth: With a bandwidth of over 250 MHz, this switch can handle high-speed data transmission with minimal signal degradation, making it ideal for data-intensive applications.
• Low On-State Resistance: The low on-state resistance (typically 5 ohms at 3.3V) allows for efficient signal switching with minimal insertion loss.
• Quick Switching: Fast switch times (turn-on and turn-off times of less than 0.25 ns) enable high-speed operation for time-sensitive signal routing.
• Bidirectional Operation: The 74CB3Q3257DGVRE4 supports bidirectional data flow, providing versatility in signal routing for both multiplexing and demultiplexing functions.
• Low Power Consumption: Designed with power-saving in mind, this device has a very low quiescent current, which is ideal for battery-operated equipment.
