General description

The CBTS3257 is a quad 1-of-2 high-speed TTL-compatible 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.

Output Enable (OE) and select-control (S) inputs select the appropriate B1 and B2 outputs for the A-input data.

Internal Schottky diode provides I/O undershoot protection.

The CBTS3257 is characterized for operation from ?40 to +85 Cel.

Features

  • 5 Ohm switch connection between two ports
  • TTL-compatible input levels
  • Schottky diodes on I/O clamp undershoot
  • Minimal propagation delay through the switch
  • Latch-up protection exceeds 500 mA per JESD78
  • ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
