Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C. 3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

All typical values are at VCC = 5 V, Tamb = +25°C ambient and maximum loading. 2. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is determined by the lowest voltage of the two (A or B) terminals. 3. These parameters are determined by device characterization, but is not production tested. 4. Not more than one output should be shorted at one time. Duration of the test should not exceed one second. 5. Per TTL driven input (VI = 3.4 V, control inputs only); A and B pins do not contribute to ICC. 6. This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified frequency. The A and B inputs generate no significant AC or DC currents as they transition. this parameter is not tested, but is guaranteed by design. 2000 Sep 01 4 Philips Semiconductors Product specification 16-bit controlled enable rate 1-of-2 multiplexer/demultiplexer with precharged outputs and Schottky undershoot protection for live insertion CBT6832E AC CHARACTERISTICS VCC = 5.0 V ±0.5 V; GND = 0 V; CL = 50 pF, RL = 500 Ω SYMBOL tPLH tPHL tPZH tPZL PARAMETER Propagation delay1 A to B Bus enable time SEL to A, B TEST CONDITIONS CONDITIONS Waveform 1 Waveform 2 10 5 LIMITS MIN TYP 0.25 30 25 MAX UNIT ns ns tPHZ Bus disable time 0.5 6 Waveform 2 ns tPLZ SEL to A, B 0.5 7 NOTE: 1.
