74HCT595
8-Bit Serial-In/Serial-Out or Parallel-Out Shift Register with 3-State Controlled Outputs
The 74HCT595 is an 8-bit serial-in/serial-out or parallel-out shift register with 3-state outputs designed for 4.5V to 5.5V VCC operation.
The device integrates an 8-bit shift register and an 8-bit D-type storage register. The storage register features parallel 3-state outputs. The shift register provides a clear input (SRCLR) with direct overriding function, a serial input (SER) and a serial output (QH') to implement cascading. When output enable input (OE) is held low, the data in storage register will appear at the outputs. When OE is held high, all outputs except QH' are in high-impedance state. OE does not affect internal register data and the serial output (QH').
Both the shift register and storage register have separate clocks. The shift register clock (SRCLK) and storage register clock (RCLK) are positive-edge triggered. If the SRCLK and RCLK are connected together, the shift register always leads one clock pulse than the storage register all the time.
The 74HCT595 is available in Green TSSOP-16 and SOIC-16 packages. It operates over an operating temperature range of -40℃ to +125℃.
