Notes
1. The levels must be measured with load circuits; 1.2 kΩ at 3 V (TTL load); CL = 50 pF.
2. The effects of rise and fall times are included in the calculation of tOHD;DAT and tPD. Timings and levels refer to
drawings and conditions illustrated in Fig.39.
3. The crystal oscillator drive level is typical 0.28 mW.
