6.6 Switching Characteristics

At TA = –40°C to 85°C, VCC = 3 V to 5.5 V, CL = 15 pF, RL = 120 Ω, RIREF = 1.5 kΩ, and VLED = 5 V, unless otherwise noted. Typical values are at TA = 25°C and VCC = 3.3 V.

tD0 Propagation delay time(1) SCLK↑ to SOUT 8 20 ns
tD1 LAT↑ to OUTR0 on-off, BCR, -G, -B = 7Fh 22 45 ns
tD2 BLANK↓↑ to OUTR0 on-off, BCR, -G, -B = 7Fh 15 30 ns
tD3 OUTRn on to OUTGn on, OUTGn on to OUTBn on,
OUTBn on to OUTRn + 1 on, BCR, -G, -B = 7Fh		 3 6 ns
tD4 OUTRn off to OUTGn off, OUTGn off to OUTBn off,
OUTBn off to OUTRn + 1 off, BCR, -G, -B = 7Fh		 3 6 ns
tD5 LAT↑ to IOUTn changing by global brightness control (BC data are 0Ch–72h or 72h–0Ch) 20 50 ns
tON_ERR Output on-time error(2) On-off latched data = 1, BCR, -G, -B = 7Fh, 20 ns BLANK low level one-shot pulse input –11 5 ns
(1) Propagation delay, tD3 (OUTRn on to OUTGn on, OUTGn on to OUTBn on, OUTBn on to OUTRn + 1 on) is calculated by the formula:
tD3 (ns) = (the propagation delay between OUTR0 to OUTB7 = on) / 23
tD4 (OUTRn to OUTGn = off, OUTGn to OUTBn = off, OUTBn to OUTRn + 1 = off) is calculated by the formula:
tD4 (ns) = (the propagation delay between OUTR0 to OUTB7 = off) / 23
(2) Output on-time error is calculated by the formula: tON_ERR (ns) = tOUT_ON – BLANK low-level pulse duration. tOUT_ON is the actual on-time of the constant current output.
