The 3-state outputs can interface with and drive  
data lines of bus-organized systems. With all but  
one of the common outputs disabled (at the  
high-impedance state), the low impedance of the  
single enabled output drives the bus line to a high  
or low logic level. Each output has its own  
output-enable (OE) input. The outputs are  
disabled when their respective OE is high.

The SN54HC253 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74HC253 is characterized for operation from –40°C to 85 °C.
