Octal Bus Transceiver  
with 25Series Resistors in the Outputs  
General Description  
Features  
25series resistors in the outputs eliminates the need  
This device is an octal bus transceiver designed for asyn-  
chronous two-way data flow between the A and B busses  
and is functionally equivalent to the 74F645. The 25Ω  
series resistors in the outputs reduce ringing and eliminate  
the need for external resistors. Both busses are capable of  
sinking 12 mA, sourcing 15 mA, have 3-STATE outputs,  
and a common output enable pin. The direction of data flow  
is determined by the transmit/receive (T/R) input. The  
74F2645 is a low power version of the 74F245 with 25Ω  
series resistors in the outputs.
