SN54F21

Overview
• Package Options Include Plastic Small-Outline Packages, Ceramic Chip Carriers, and Standard Plastic and Ceramic 300-mil DIPs description These devices contain two independent 4-input AND gates.
They perform the Boolean functions Y = A • B • C • D or Y = A + B + C + D in positive logic.
The SN54F21 is characterized for operation over the full military temperature range of − 55°C to 125°C.
The SN74F21 is characterized for operation from 0°C to 70°C.
