SN74CBT3257DBQR Description

Short technical summary and product information.

The SN74CBT3257DBQR from Texas Instruments is a 4-bit, 1-of-2 high-speed TTL-compatible FET multiplexer/demultiplexer. This device features low on-state resistance, enabling connections with minimal propagation delay. The select-control (S) and output-enable (OE) inputs are used to select the appropriate B1 and B2 outputs for the A-input data.

 

This component is designed for applications requiring efficient signal routing. It operates over a temperature range of -40°C to 85°C and requires a single supply voltage between 4.5V and 5.5V. The device is available in a 16-SSOP package, suitable for surface mounting.

 

Key electrical characteristics include a typical on-state resistance of 5000 mΩ and a maximum on-state resistance of 20000 mΩ. It supports a bandwidth of 200 MHz and can handle an input/output continuous current of up to 128 mA. The OFF-state leakage current is a maximum of 1 µA.

 

Note: This product is obsolete and no longer in production. New designs should consider an alternate product.
