FEATURES

  • 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 JESDEC Standard JESD78 which exceeds 100 mA

DESCRIPTION

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 to +85°C.

Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2.

All typical values are at VCC = 5 V, Tamb = 25 °C. 2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND 3. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is determined by the lowest voltage of the two (A or B) terminals.
