SN74CB3Q3251
SN74CB3Q3251 is 2.5-V/3.3-V LOW-VOLTAGE HIGH-BANDWIDTH BUS SWITCH manufactured by Texas Instruments.
FEATURES
- High-Bandwidth Data Path (up to 500 MHz (1))
- Equivalent to IDTQS3VH251 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 p F Typ)
- Fast Switching Frequency (f OE or f S = 20 MHz Max)
