INTEGRATED CIRCUITS CBT6800 10-bit bus switch with precharged outputs for live insertion Product specification Supersedes data of 1999 Mar 18 1999 Oct 28 Philips Semiconductors Philips Semiconductors Product specification 10-bit bus switch with precharged outputs for live insertion Features - 5 Ω switch connection between two ports - TTL patible input and output levels - Outputs are precharged by bias voltage to minimize signal distortion during live insertion DESCRIPTION The CBT6800 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 CBT6800 is organized as one 10-bit switch with a single enable (ON) input. When ON is low, the switch is on and port A is connected to port B. When ON 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 CBT6800 is characterized for operation from - 40°C to 85°C. - Latch-up protection exceeds 100 m A per JESD78 - ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101 QUICK REFERENCE DATA SYMBOL t PLH t PHL CIN COUT ICCZ PARAMETER Propagation delay An to Bn or Bn to An Input capacitance - control pin Output capacitance - I/O pins Total supply current CONDITIONS Tamb = 25°C; GND = 0 V CL = 50 p F; VCC = 5 V VI = 0 V or VCC Outputs disabled; VO = 0 V or VCC Outputs disabled; VCC =5.5 V TYPICAL 250 3.5 8.2 1 UNIT ps p F p F µA ORDERING INFORMATION PACKAGES 24-Pin Plastic TSSOP Type I TEMPERATURE RANGE - 40°C to +85°C ORDER CODE CBT6800 PW DH DWG NUMBER SOT355- 1 PIN CONFIGURATION PIN DESCRIPTION PIN NUMBER 1 13 SYMBOL OE BIASV A1- A10 B1- B10 GND VCC NAME AND FUNCTION Output enable Precharge bias voltage input A-port I/O pins B-port...
