The clocks can be tied together, in which case the shift register is one clock pulse ahead of the storage register. 6.9 Switching Characteristics: VCC = 3.3 V ± 0.3 V over operating free-air temperature range (unless otherwise noted) FROM TO LOAD PARAMETER TEST CONDITIONS MIN TYP MAX UNIT (INPUT) (OUTPUT) CAPACITANCE TA = 25°C 80(1) 120(1) CL = 15 pF TA = –40°C to 85°C 70 TA = –40°C to 125°C Recommended 60 fmax MHz TA = 25°C 55 105 CL = 50 pF TA = –40°C to 85°C 50 TA = –40°C to 125°C Recommended 40 TA = 25°C 6(1) 11.9(1) tPLH RCLK QA – QH CL = 15 pF TA = –40°C to 85°C 1 13.5 ns TA = –40°C to 125°C Recommended 1 14.9 TA = 25°C 6(1) 11.9(1) tPHL RCLK QA – QH CL = 15 pF TA = –40°C to 85°C 1 13.5 ns TA = –40°C to 125°C Recommended 1 14.9 TA = 25°C 6.6(1) 13(1) tPLH SRCLK QH' CL = 15 pF TA = –40°C to 85°C 1 15 ns TA = –40°C to 125°C Recommended 1 16.4 TA = 25°C 6.6(1) 13(1) tPHL SRCLK QH' CL = 15 pF TA = –40°C to 85°C 1 15 ns TA = –40°C to 125°C Recommended 1 16.4 (1) On products compliant to MIL-PRF-38535, this parameter is not production tested.
