(X = 1,2) PROGRAMMING PARAMETERS (See Figure 24)
Notes: These parameters are not 100% tested.
V2RO, V3RO OUTPUT TIMING. (See Figure 23)
Notes: 1. See Figure 23 for timing diagram.
Notes: 2. See Figure 18 for equivalent load.
Notes: 3. This parameter describes the lowest possible Vcc / V1 level for which the outputs V2RO, and V3RO will be correct with respect to their
inputs ( V2, V3).
Notes: 4. The above parameters are not 100% tested.
