5.6 Timing Requirements, VCC = 5 V ± 0.5 V

VCC = 5 V ± 0.5 V, over recommended operating free-air temperature range (unless otherwise noted) (see Load Circuit and Voltage Waveforms)
TA = 25°C MIN MAX UNIT
MIN MAX
tw Pulse duration SRCLK high or low 5 6 ns
RCLK high or low 5 6
SRCLR low 5.2 6.2
tsu Setup time SER before SRCLK↑ 3 4 ns
SRCLK↑ before RCLK↑(1) 5 6
SRCLR low before RCLK↑ 5 6
SRCLR high (inactive) before SRCLK↑ 2.5 3.5
th Hold time SER after SRCLK↑ 2 3 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.
