SWITCHING CHARACTERISTICS
At T_A = –40°C to +85°C, V_CC = 4 V to 17 V or V_CC = V_REG = 3 V to 5.5 V, C_VREG = 1 µF, C_L = 15 pF, R_L = 68 Ω, and V_LED = 5
V, unless otherwise noted. Typical values are at T_A = +25°C and V_CC = 12 V.

(1) The propagation delays are calculated by t_D2a = t_D0a – t_D1a or t_D2b = t_D0b – t_D1b.
(2) The generation timing of the internal latch pulse changes depending on the SCKI clock frequency; see the Internal Latch Pulse
Generation Timing section.
