Overview
UNISONIC TECHNOLOGIES CO.
, LTD U74HC594 8-BIT SERIAL-IN SHIFT REGISTER WITH OUTPUT REGISTERS  DESCRIPTION The UTC U74HC594 contains an 8-bit serial-in parallel-out register.
The Serial Data Input (SER) input will shift into the internal shift register during every LOW-to-HIGH transition on the ( SRCLR ) input.
The storage register will storage the 8-bit data from the shift register during the LOW-to-HIGH transition on the ( RCLR ) input.
A serial (QH’) output is provided for cascading purposes.
 FEATURES * Wide supply voltage range from 2.
0V to 6.
0V * Low static power consumption; ICC=8μA (Max.
) * 8 bit counter with register  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HC594L-S16-R U74HC594G-S16-R U74HC594L-P16-R U74HC594G-P16-R Package SOP-16 TSSOP-16 CMOS IC SOP-16 TSSOP-16 Packing Tape Reel Tape Reel  MARKING www.
