Advantages of the CBT6832 include a propagation delay of 250 ps, resulting from 5 Ω channel resistance, and low I/O capacitance. A port demultiplexes to either 1B and 2B, or to both. The switch is bi-directional. 12A 20 13B1 21 14B1 22 14A 23 15B1 24 16B1 25 16A 26 VBIAS1 27 SEL1 28 SW00478 QUICK REFERENCE DATA SYMBOL t PLH t PHL CIN COUT B COUT A C on 1 C on 2 PARAMETER Propagation delay An to Bn or Bn to An Input capacitance B capacitance A capacitance One channel on capacitance Both channels on capacitance CONDITIONS Tamb = 25°C; GND = 0 V CL = 50 p F; VCC = 5 V VI = 0 V or VCC Outputs disabled; VO = 0 V Outputs disabled; VO = 0 V One B enabled; VO = 0 V Both B channels enabled; VO = 0 V TYPICAL 0.25 4.5 8 13 21 34 UNIT ns p F p F p F p F p F ORDERING INFORMATION PACKAGES 56-Pin Plastic TSSOP Type II TEMPERATURE RANGE 0°C to +70°C ORDER CODE CBT6832 DGG DWG NUMBER SOT364-1 2000 Jul 18 853-2204 24151 Philips Semiconductors Product specification 16-bi...
