CBT6810

INTEGRATED CIRCUITS CBT6810 10-bit bus switch with precharged outputs and Schottky undershoot protection for live insertion Product specification 1999 Apr 05 Philips Semiconductors Philips Semiconductors Product specification 10-bit bus switch with precharged outputs and Schottky undershoot protection for live insertion CBT6810 FEATURES 5Ω switch connection between port A and port B TTL compatible input and output levels Undershoot protection included to prevent shoot through level changes DESCRIPTION The CBT6810 provides ten 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 CBT6810 is organized as one 10-bit switch with a single 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-kΩ resistor. The CBT6810 is characterized for operation from 0°C to 85°C. Bias voltage pre-charges the outputs to minimize signal distortion during live insertion QUICK REFERENCE DATA SYMBOL tPLH tPHL CIN CIO PARAMETER Propagation delay An to Bn or Bn to An Input capacitance Input/output capacitance CONDITIONS Tamb = 25°C; GND = 0V CL = 50pF; VCC = 5V VI = 0V or VCC Outputs di...
