1. Oscillator period T (T = Tr + Tf) is determined by the external components R1, R2 and C3 where Tr = (0.6931)R2*C3 and Tf = (0.6931)R1*C3.

The other timing characteristics are some multiple of the oscillator timing shown in the table. The timing shown should accommodate the

NFPA72, ANSI S3.41, and ISO8201 audible emergency evacuation signals.

2. Typicals are not guaranteed.

3. Time is typical-depends on what point in cycle the signal is applied.

Table 3

. AC Electrical Characteristics (Refer to Timing Diagram Figure 3 and Figure 4. TA = 25°C, VDD = 9.0 V,

Component Values from Figure 5.) (continued)
