74HC595 Datasheet | SG Micro

DESCRIPTION The 74HC595 is an 8-bit serial-in/serial-out or parallel-out shift register with 3-state outputs designed for 2.0V 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 (S- - R- - - C- - L- - R- ) with direct overriding function, a serial input (SER) and a serial output (QH') to implement cascading. When output enable input (O- - - - E- ) is held low, the data in storage register will appear at the outputs. When O- - - - E- 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. The 74HC595 is available in Green TSSOP-16, SOIC-16, SSOP-16 (209mil) and TQFN-2.5×3.5-16L packages. It operates over an operating temperature range of -40℃ to +125℃. FEATURES - Wide Supply Voltage...
