description
These devices contain four independent 2-input
positive-NAND buffers/drivers. They perform the
Boolean functions Y = A
B or Y = A + B in positive
logic.
The SN54AS1000A is characterized for operation
over the full military temperature range of 55
°C
to 125
°C. The SN74AS1000A is characterized for
operation from 0
°C to 70°C.
