JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD. 8-bit Serial-in, Serial or Parallel-out Shift Register with Output Latches; 3-state CJ74HC/HCT595 Logic 1 Introduction 3 Features The CJ74HC/HCT595 is an 8-bit serial-in/serial or • parallel-out shift register with a storage register and 3state outputs. Both the shift and storage register have Input levels: - For CJ74HC595: CMOS level - For CJ74HCT595: TTL level separate clocks. The device features a serial input (DS) and a serial output (Q7S) to enable cascading and an • 8-bit serial input • 8-bit serial or parallel output asynchronous reset /MR input. A LOW on /MR will reset the shift register. Data is shifted on the LOW-to-HIGH • Storage register with 3-state outputs • Shift register with direct clear transitions of the SHCP input. The data in the shift • Specified from -40°C to +125°C register is transferred to the storage register on a LOWto-HIGH transition of the STCP input. If both clocks are 4 Applications connected together, the shift register will always be one clock pulse ahead of the storage register. Data in the • Network switches storage register appears at the output whenever the output enable input (/OE) is LOW. • Power infrastructure • LED displays A HIGH on /OE causes the outputs to assume a high- • Servers impedance OFF-state. Operation of the /OE input does not affect the state of the registers. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
