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 Features - 5Ω switch connection between port A and port B - TTL patible input and output levels - Undershoot protection included to prevent shoot through level changes DESCRIPTION The CBT6810 provides ten bits of high-speed TTL-patible 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 t PLH t PHL CIN CIO PARAMETER Propagation delay An to Bn or Bn to An Input capacitance Input/output capacitance CONDITIONS Tamb = 25°C; GND = 0V CL = 50p F; VCC = 5V VI = 0V or VCC Outputs disabled; VO = 0V or VCC TYPICAL 250 3.5 9.0 UNIT ps p F p F ORDERING INFORMATION PACKAGES 24-Pin Plastic TSSOP Type I TEMPERATURE RANGE - 40°C to +85°C OUTSIDE NORTH AMERICA CBT6810 PW NORTH AMERICA CBT6810PW DH DWG NUMBER SOT355- 1 PIN CONFIGURATION PIN DESCRIPTION PIN NUMBER 1 SYMBOL OE BIASV A1- A10 B1- B10 GND VCC NAME AND FUNCTION Output enable Bias supply pin A - port side B - port side with active pullup Ground (V) Positive supply voltage OE A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 GND 1 2 3 4 5 6...
