Additional Details

The TC74VHC595F-EL is available in a SOP package, suitable for surface-mount technology. It operates over a temperature range of -40°C to +85°C. The device is controlled by three pins: a serial data input (SER), a shift register clock input (SRCLK), and a latch clock input (RCLK). The Output Enable (OE) pin, when high, disables the outputs, placing them in a high-impedance state.
