Q & A
- What is the primary function of the 74HCT373PW,112?
The 74HCT373PW,112 is an octal D-type transparent latch with 3-state outputs, designed for high-speed data buffering and storage.
- What is the package type of the 74HCT373PW,112?
The package type is TSSOP20.
- What is the logic family of the 74HCT373PW,112?
The logic family is HCT.
- What is the supply voltage range for the 74HCT373PW,112?
The supply voltage range is from 2.0 V to 6.0 V.
- What are the key features of the 74HCT373PW,112?
Key features include fast propagation delays, low power consumption, high noise immunity, and compliance with JEDEC standard JESD8-5A.
- How does the latch enable (LE) input function?
When LE is HIGH, data at the inputs enter the latches, making them transparent. When LE is LOW, the latches store the information present at the inputs before the HIGH-to-LOW transition of LE.
- What is the purpose 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.
- What are some common applications of the 74HCT373PW,112?
Common applications include data storage systems, communication systems, data management systems, and various automotive and consumer devices.
