U74HCT595

UNISONIC TECHNOLOGIES CO., LTD U74HCT595 8-BIT SHIFT REGISTERS WITH LATCHED 3-STATE OUTPUT REGISTERS  DESCRIPTION The UTC 74HCT595 contains an 8-bit register with asynchronous reset input and an 8-bit latch with output enable input. Data on the Serial Data Input (SER) will be shift into the internal shift register during every LOW-to-HIGH transition on the Shift Clock. The latch will latch the 8-bit data from the shift register during the LOW-to-HIGH transition on the Latch Clock. The shift register also provides a serial output.  FEATURES * Operation Voltage Range: 4.5V ~ 5.5V * High Noise Immunity * Output Compatibility with CMOS and TTL * 8-Bit Serial-In, Parallel-Out Shift * Inputs are TTL voltage compatiable  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HCT595L-S16-R U74HCT595G-S16-R U74HCT595L-P16-R U74HCT595G-P16-R Package SOP-16 TSSOP-16 CMOS IC SOP-16 TSSOP-16 Packing Tape Reel Tape Reel  MARKING www.unisonic.com.tw Copyright © 2022 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-666.D U74HCT595  PIN CONFIGURATION CMOS IC OE SRCLR  FUNCTION TABLE FUNCTION SRCLK A Low-Level on SRCLR only affects the shift X registers.
