Q & A
- What is the primary function of the 74HCT373D,652?
The primary function is to act as an octal D-type transparent latch with 3-state outputs, providing interface and storage functions for microprocessor-based systems.
- What is the supply voltage range for the 74HCT373D,652?
The supply voltage range is from 4.5 V to 5.5 V.
- What are the logic switching levels for this device?
The logic switching levels are TTL (Transistor-Transistor Logic).
- What is the propagation delay time for the 74HCT373D,652?
The propagation delay time is 14 ns.
- What is the operating temperature range for this device?
The operating temperature range is from -40°C to +125°C.
- Does the 74HCT373D,652 have ESD protection?
- What types of packages are available for the 74HCT373D,652?
It is available in SO20, TSSOP20, and DHVQFN20 packages.
- How does the latch enable (LE) input work?
When LE is HIGH, data at the inputs enter the latches, and when LE is LOW, the latches store the information present at the inputs before 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, but does not affect the state of the latches.
- Is the 74HCT373D,652 compliant with any industry standards?
