Additional Details

The TC74VHC374FS is available in a SOP package, suitable for surface mount assembly. The operating temperature range is from -40°C to +85°C. The device has an Output Enable (OE) pin, which, when asserted high, places the outputs in a high-impedance state, effectively disconnecting the device from the bus. All inputs are protected against electrostatic discharge (ESD).
