SN5433, SN54LS33, SN7433, SN74LS33
Quadruple 2-Input Positive-NOR Buffers With Open-Collector Outputs
These devices contain four independent 2-input NOR buffer gates with open-collector outputs. Open-
collector outputs require resistive pull-up to perform logically but can deliver higher V
OH
levels and
are commonly used in wired-AND applications.
The SN5433 and SN54LS33 are characterized for operation over the full military temperature range
of -55°C to 125°C. The SN7433 and SN74LS33 are characterized for operation from 0°C to 70°C.
