6.10 Timing Requirements: V_CC = 3.3 V ± 0.3 V

over recommended operating free-air temperature range, V_CC = 3.3 V ± 0.3 V. See Figure 6-1.

			T_A = 25°C		SN74LV594A –40°C TO 85°C		SN74LV594A –40°C TO 125°C		UNIT
			MIN	MAX	MIN	MAX	MIN	MAX	UNIT
t_w	Pulse duration	RCLK or SRCLK high or low	5.5		5.5		6.5		ns
t_w	Pulse duration	RCKR or SCRCLR low	5		5		6		ns
t_su	Setup time	SER before SRCLK↑	3.5		3.5		4		ns
		SRCLK↑ before RCLK↑	8		8.5		9.5
		SCRCLR low before RCLK↑⁽¹⁾	8		9		10
		SRCLR high (inactive) before SRCLK↑	4.2		4.8		5.5
		RCLK high (inactive) before RCLK↑	4.6		5.3		6
t_h	Hold time	SER after SRCLK↑	1.5		1.5		2		ns

(1) This setup time allows the storage register to receive stable data from the shift register. The clocks can be tied together, in which case the shift register is one clock pulse ahead of the storage register.
