6.8 Switching Characteristics - Receiver

over recommended ranges of supply voltage and operating free-air temperature range (unless otherwise noted)⁽³⁾

PARAMETER		TEST CONDITIONS				TYP⁽¹⁾	UNIT
t_PLH	Propagation delay time, low- to high-level output	C_L = 150 pF,		See Figure 7-3		150	ns
t_PHL	Propagation delay time, high- to low-level output	C_L = 150 pF,		See Figure 7-3		150	ns
t_en	Output enable time	C_L = 150 pF,	R_L = 3 kΩ,		See Figure 7-4	200	ns
t_dis	Output disable time	C_L = 150 pF,	R_L = 3 kΩ,		See Figure 7-4	200	ns
t_sk(p)	Pulse skew⁽²⁾	See Figure 7-3				50	ns

(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.
