OR:  

The CBT3251 is a 1-of-8 high-speed TTL-compatible FET multiplexer/demultiplexer. The low ON-resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.

When output enable (OE) is LOW, the CBT3251 is enabled. S0, S1, and S2 select one of the B outputs for the A-input data.

The CBT3251 is characterized for operation from -40 °C to +85 °C.

Features and benefits

  • 5 Ω switch connection between two ports
  • TTL-compatible input levels
  • Minimal propagation delay through the switch
  • ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
  • Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
