Q & A
- What is the primary function of the 74HC4514PW,118?
The primary function is to act as a 4-to-16 line decoder/demultiplexer with input latches.
- What is the supply voltage range for the 74HC4514PW,118?
The supply voltage range is from 2.0 V to 6.0 V.
- What type of logic switching levels does the 74HC4514PW support?
The 74HC4514PW supports CMOS logic switching levels, while the 74HCT4514 supports TTL logic levels.
- How many outputs does the 74HC4514PW have?
The device has 16 outputs (Q0 to Q15).
- What is the package type of the 74HC4514PW,118?
The package type is TSSOP24.
- What is the operating temperature range of the 74HC4514PW,118?
The operating temperature range is from -40°C to +125°C.
- Does the 74HC4514PW,118 have ESD protection?
Yes, it has ESD protection: HBM (ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V), CDM (ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V).
- What are some common applications of the 74HC4514PW,118?
Common applications include digital multiplexing, address decoding, and hexadecimal/BCD decoding.
- How does the latch enable input (LE) function?
When LE is HIGH, the selected output is determined by the data on A0 to A3. When LE goes LOW, the last data present at A0 to A3 are stored in the latches and the outputs remain stable.
- What is the effect of the enable input (E) on the outputs?
When E is LOW, the selected output, determined by the contents of the latch, is HIGH. At E HIGH, all outputs are LOW.
