9.2.2.4 Response Time

Response time is a function of input over-drive. See the Typical Characteristics graphs for typical response times. The rise and fall times can be determined by the load capacitance (CL), load/pull-up resistance (RPULLUP) and equivalent collector-emitter resistance (RCE).

  • The rise time (τR) is approximately τR~ RPULLUP × CL
  • The fall time (τF) is approximately τF ~ RCE × CL
    • RCE can be determined by taking the slope of Figure 3 in its linear region at the desired temperature, or by dividing the VOL by IOUT
