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.
