The ’AHCT258 devices are designed to multiplex  
signals from 4-bit data sources to 4-output data  
lines in bus-organized systems. The 3-state  
outputs do not load the data lines when the  
output-enable (OE) input is at the high logic level.

through a pullup resistor; the minimum value of  
the resistor is determined by the current-sinking  
capability of the driver.

The SN54AHCT258 is characterized for  
operation over the full military temperature range  
of –55°C to 125°C. The SN74AHCT258 is  
characterized for operation from –40°C to 85°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and  
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not  
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.  
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.  
2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace  
length of zero.
