Notes
1. The levels must be measured with load circuits; 1.2 kΩ at 3 V (TTL load); C_L = 50 pF.
2. The effects of rise and fall times are included in the calculation of t_OHD;DAT, t_PD and t_PDZ. Timings and levels refer to
drawings and conditions illustrated in Figs 15 and 16.
3. Order number: Philips 4322 143 05291.
