SN74CB3Q3305 Overview
Key Specifications
Package: TSSOP
Mount Type: Surface Mount
Pins: 8
Max Voltage (typical range): 3.6 V
Description
The SN74CB3Q3305 device is a high-bandwidth FET bus switch using a charge pump to elevate the gate voltage of the pass transistor, providing a low and flat ON-state resistance (ron). The low and flat ON-state resistance allows for minimal propagation delay and supports switching input voltage beyond the supply on the data input/output (I/O) ports.
Key Features
- High-bandwidth data path (up to 500 MHz)1
- 5-V tolerant I/Os with device powered up or powered down
- Low and flat ON-state resistance (ron) characteristics over operating range (ron = 3 Ω typical)
- Supports input voltage beyond supply on data I/O ports – 0 to 5 V switching with 3.3 V VCC – 0 to 3.3 V switching with 2.5 V VCC
- Bidirectional data flow with near-zero propagation delay
