Q & A
- What is the primary function of the 74HC373D-Q100,118? The primary function is to act as an octal D-type transparent latch with 3-state outputs.
- What are the supply voltage ranges for this component? The supply voltage range is from 2.0 V to 6.0 V.
- What are the logic switching levels for the 74HC373D? The logic switching levels are CMOS.
- What is the propagation delay of the 74HC373D? The propagation delay is 12 ns.
- Does the 74HC373D have ESD protection? Yes, it has ESD protection with HBM > 2000 V and CDM > 1000 V.
- What are the operating temperature ranges for this component? The operating temperature ranges from -40 °C to +125 °C.
- What package options are available for the 74HC373D? It is available in SO20 (SOT163-1) package among others.
- How does the latch enable (LE) input function? When LE is HIGH, data at the inputs enter the latches. When LE is LOW, the latches store the information that was present at the inputs a set-up time preceding the HIGH-to-LOW transition of LE.
- What is the effect of the output enable (OE) input? A HIGH on OE causes the outputs to assume a high-impedance OFF-state without affecting the state of the latches.
- Is the 74HC373D compliant with any industry standards? Yes, it complies with JEDEC standards and has latch-up performance exceeding 100 mA per JESD 78 Class II Level B.
