General description

The CBT6820 provides twenty bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switch allows bi-directional connections to be made while adding near-zero propagation delay. The device also precharges the B port to a user-selectable bias voltage (BIASV) to minimize live-insertion noise.

The device is organized as two 10-bit switch with individual enable (OE) input. When OE is low, the switch is on and port A is connected to port B. When OE is high, the switch between port A and port B is open and the B port is precharged to BIASV through the equivalent of a 10 kOhm resistor.

Special clamp circuitry and Schottky diode clamps to ground are used to prevent an under voltage on the A side (Vin < GND) from causing the B side precharge voltage to drop below the '1' state.

Features

  • TTL compatible inputs and outputs
  • 5 Ohm switch connection between two port A and port B
  • Thin shrink small outline (TSSOP)
  • Undershoot protection included to prevent shoot through level changes
  • Bias voltage pre-charges the outputs to minimize signal distortion during live insertion
  • 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
