SN74CB3Q3245 Description
/ORDERING INFORMATION The SN74CB3Q3245 is a high-bandwidth FET bus switch utilizing 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 rail-to-rail switching on the data input/output (I/O) ports.
SN74CB3Q3245 Key Features
- High-Bandwidth Data Path (up to 500 MHz (1))
- Equivalent to IDTQS3VH384 Device
- 5-V Tolerant I/Os With Device Powered Up or Powered Down
- Low and Flat ON-State Resistance (ron) Characteristics Over Operating Range (ron = 4 Ω Typ)
- Rail-to-Rail Switching 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
- Low Input/Output Capacitance Minimizes Loading and Signal Distortion (Cio(OFF) = 3.5 pF Typ)
- Fast Switching Frequency (fOE = 20 MHz Max)
