SN74CBT3244DBQR Description

Short technical summary and product information.

The SN74CBT3244DBQR from Texas Instruments is an 8-bit, 1:1 (SPST) general-purpose FET bus switch. It features a high-bandwidth data path capable of up to 200 MHz, making it suitable for high-speed signal routing.

 

The device operates with a VCC range of 4.5 V to 5 V and supports data I/Os with signaling levels from 0 to 5 V. Key electrical characteristics include a typical ON-state resistance of 5 Ohms and a maximum OFF-state leakage current of 5 µA. The low input/output capacitance minimizes loading and signal distortion.

 

Designed for TTL compatibility, the control inputs can be driven by TTL or 5-V/3.3-V CMOS logic. The SN74CBT3244DBQR offers bidirectional data flow with near-zero propagation delay. It is supplied in a 20-SSOP package, suitable for surface mounting.

 

This part is noted as 'NOT RECOMMENDED FOR NEW DESIGNS'.
