over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)⁽³⁾ (see Figure 9-1)

PARAMETER		TEST CONDITIONS			MIN	TYP⁽¹⁾	MAX	UNIT
Maximum data rate (see Figure 7-1)		R_L = 3 kΩ	C_L = 1000 pF		250			kbit/s
			C_L = 250 pF,	V_CC = 3 V to 4.5 V	1000
			C_L = 1000 pF,	V_CC = 4.5 V to 5.5 V	1000
t_sk(p)	Pulse skew⁽²⁾	C_L = 150 pF to 2500 pF	R_L = 3 kΩ to 7 kΩ,	See Figure 7-2		100		ns
SR(tr)	Slew rate, transition region (see Figure 7-1)	V_CC = 3.3 V, R_L = 3 kΩ to 7 kΩ	C_L = 150 pF to 1000 pF		18		150	V/μs

(1) All typical values are at V_CC = 3.3 V or V_CC = 5 V, and T_A = 25°C.

(2) Pulse skew is defined as |t_PLH − t_PHL| of each channel of the same device.

(3) Test conditions are C1−C4 = 0.1 μF at V_CC = 3.3 V ± 0.3 V; C1 = 0.047 μF, C2−C4 = 0.33 μF at V_CC = 5 V ± 0.5 V.
