Motorola SN54/74LS02 Data Sheet
Summary
This comprehensive guide details the electrical specifications and operational parameters for quad 2-input NOR Gate integrated circuits (ICs), including both SN54 and SN74 versions. It covers essential data like voltage ranges, input/output current limits, timing characteristics (rise and fall times), and performance across varying ambient temperatures (AC and DC). This manual is essential reading for electronics engineers and hardware designers who need reliable specifications when integrating LS TTL logic gates into their circuit designs.

Frequently Asked Questions
What is the recommended supply voltage range for these gates?
The guaranteed operating range is from 4.5V (Min) to 5.5V (Max).
What are the maximum current draw specifications, particularly when outputting low voltage?
When outputting LOW (OL), the minimum guaranteed output current is 8.0 mA per terminal.
Can I use this chip if my operating temperature exceeds room temperature?
Yes, the standard operating ambient temperature range is from -55°C to 125°C.
How quickly do these gates transition (turn-off delay)?
The guaranteed turn-off delay time ($t_{PLH}$) is between 10 ns and 15 ns.
