Description

The 74CBTLV3257PW is a high-speed, low-voltage quad 2:1 multiplexer/demultiplexer designed for digital signal switching applications. It features four independent channels, each capable of multiplexing digital signals. The device operates with a power supply voltage range of 2.3V to 3.6V and is ideal for translating between different voltage levels.
The 74CBTLV3257PW is part of the CBTLV series, optimized for minimizing propagation delay and power consumption, with typical propagation delays under 0.25ns. It supports bidirectional data flow, making it suitable for both data routing and signal isolation tasks.
Key characteristics include low ON-state resistance, which aids in maintaining signal integrity, and high bandwidth, supporting fast data rates suitable for modern digital systems. The device is packaged in a compact TSSOP (Thin Shrink Small Outline Package) for efficient PCB layout. It's widely used in applications such as data acquisition systems, communication equipment, and other digital circuit designs requiring efficient signal routing.

Pinout

The 74CBTLV3257PW is a low-voltage quad 2:1 multiplexer/demultiplexer with a pin count of 16. It functions as a high-speed bus switch, providing a way to select between two data sources for each of the four outputs. Here is a brief overview of its pin functions:
1. S (Pin 1): Select input for switching between the two data paths.
2. 1B1-1B4, 2B1-2B4 (Pins 3-6, 11-14): Data inputs for the multiplexer paths.
3. 1A, 2A (Pins 2 and 15): Common I/O for the two sets of multiplexer paths.
4. OE (Pin 7): Output Enable control. When OE is low, the device is enabled; when high, outputs are in high-impedance state.
5. VCC (Pin 16): Supply voltage.
6. GND (Pin 8): Ground.
The device is typically used for signal routing applications in digital systems. It supports both multiplexing (selecting between inputs) and demultiplexing (routing a single input to multiple outputs), and operates with a supply voltage of 1.65V to 3.6V.
