SN54ALS21A - Dual 4-Input Positive-AND Gates
Updated : 2020-01-09 14:37:47Description
These devices contain two independent 4-input positive-AND gates. They perform the Boolean functions 
or 
in positive logic.
The SN54ALS21A and SN54AS21 are characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS21A and SN74AS21 are characterized for operation from 0°C to 70°C.
