Additional Details
The TC74VCX2373FK generally operates within a supply voltage range of 1.65V to 5.5V, making it compatible with various logic levels. The propagation delay is typically in the nanosecond range, depending on the operating conditions and load capacitance. It is commonly available in surface-mount packages such as SSOP or TSSOP. The operating temperature range usually spans from -40°C to +85°C. The output enable (OE) pin, when low, enables the outputs, allowing data to pass through. When OE is high, the outputs are in a high-impedance state, effectively disconnecting the device from the bus. When the latch enable (LE) is high, the Q outputs follow the data (D) inputs. When LE is low, the Q outputs are latched, holding the last data present before the transition.
