74AHCT595F
8-Bit Serial-In/Serial-Out or Parallel-Out Shift Register with Output Latches
The 74AHCT595F is an 8-bit serial-in/serial-out or parallel-out shift register with output latches 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 parallel outputs are in high-impedance state.
Both the shift register and storage register have separate clocks. The shift register clock (SRCLK) and storage register clock (RCLK) are positive-edge triggered.
This device is highly suitable for partial power-down applications by using power-off leakage current (IOFF) circuit. When the device is powered down, the output is disabled, and the current backflow can be prevented from passing through the device.
The 74AHCT595F is available in Green TSSOP-16 and SOIC-16 packages. It operates over an operating temperature range of -40℃ to +125℃.
