PRODUCTION DATA

7.10 Switching Characteristics: Receiver

over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) (see Figure 10-1)

PARAMETER		TEST CONDITIONS⁽¹⁾	TYP⁽²⁾	UNIT
t_PLH	Propagation delay time, low- to high-level output	C_L = 150 pF, See Figure 8-3	150	ns
t_PHL	Propagation delay time, high- to low-level output	C_L = 150 pF, See Figure 8-3	150	ns
t_en	Output enable time	C_L = 150 pF, R_L = 3 kΩ, See Figure 8-4	200	ns
t_dis	Output disable time	C_L = 150 pF, R_L = 3 kΩ, See Figure 8-4	200	ns
t_sk(p)	Pulse skew⁽³⁾	See Figure 8-3	50	ns

(1) 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.

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

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