SN74BCT2241 and ′BCT2244, these devices  
provide the choice of selected combinations of  
inverting and noninverting outputs, symmetrical  
active-low output-enable (OE) inputs, and  
complementary OE and OE inputs. These devices  
feature high fan-out and improved fan-in.

The ′BCT2240 is organized as two 4-bit line  
drivers with separate output-enable (OE) inputs.  
When OE is low, the device passes data from the  
A inputs to the Y outputs. When OE is high, the  
outputs are in the high-impedance state.  
The outputs, which are designed to source or sink  
up to 12 mA, include 33-Ω series resistors to  
reduce overshoot and undershoot.  
The SN54BCT2240 is characterized for operation  
over the full military temperature range of –55°C  
to 125°C. The SN74BCT2240 is characterized for  
operation from 0°C to 70°C.
