Additional Details
The TC74VHC595F(EL,F) 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 features separate clock inputs for the shift register and the output latches, allowing for independent control of data shifting and output updating. The output enable (OE) input controls the 3-state outputs; when OE is high, the outputs are in a high-impedance state.
