SN54H55, SN54L55, SN54LS55, SN74H55, SN74LS55
2-Wide 4-Input AND-OR-INVERT Gates
These devices contain 2-wide 4-input AND-OR-INVERT gates. The ‘L55 and ‘LS55 perform the
Boolean function Y=ABCD+EFGH. The ‘H55 is expandable and performs the Boolean function
Y=ABCD+EFGH+X with X=output of SN54H60/SN74H60 or SN54H62/SN74H62. The SN54H55,
SN54L55, and the SN54LS55 are characterized for operation over the full military temperature range of
-55°C to 125°C while the SN74H55 and SN74LS55 are characterized for operation from 0°C to 70°C.
