The ’AHCT16240 devices are 16-bit buffers and  
line drivers designed specifically to improve the  
performance and density of 3-state memory  
address drivers, clock drivers, and bus-oriented  
receivers and transmitters.

These devices can be used as four 4-bit buffers,  
two8-bitbuffers, orone16-bitbuffer. Theyprovide  
inverting outputs and symmetrical active-low  
output-enable (OE) inputs.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
The SN54AHCT16240 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74AHCT16240 is characterized for operation from –40°C to 85°C.
