SN74CB3Q3245RGYR Description

Short technical summary and product information.

The SN74CB3Q3245RGYR from Texas Instruments is an 8-bit, 1:1 FET bus switch designed for low-voltage, high-bandwidth applications. It supports a VCC operating range from 2.3V to 3.6V and features data I/Os that support 0- to 5-V signaling levels. The device boasts a high bandwidth of up to 500 MHz and a low, flat ON-state resistance of typically 4 Ω.

This bus switch provides bidirectional data flow with near-zero propagation delay, making it suitable for applications requiring fast switching. It features low input/output capacitance, minimizing loading and signal distortion. The control inputs can be driven by TTL or 5-V/3.3-V CMOS logic. Undershoot clamp diodes are integrated into the data and control inputs.

Packaged in a 20-VQFN (3.5x4.5 mm) with surface mount mounting, the SN74CB3Q3245RGYR operates within a temperature range of -40°C to 85°C. Its design supports both digital and analog signals, making it applicable for interfaces like PCI, differential signal interfaces, memory interleaving, and bus isolation.
