HD74AC182/HD74ACT182
Carry Lookhead Generator
Description
The HD74AC182/HD74ACT182 is a high-speed carry lookahead generator. It is generally used with the
HD74AC181 or HD74AC381 4-bit arithmetic logic unit to provide high-speed lookahead over word
lengths of more than four bits.
Features
• Outputs Source/Sink 24 mA
