OCTAL BUS TRANSCEIVER  
WITH 3-STATE OUTPUTS  
(INVERTING AND NONINVERTING)  
The MC74F620 is an octal bus transceiver featuring inverting 3-state bus-  
compatible outputs in both send and receive directions. The B outputs are  
N
capable of sinking 64 mA and sourcing up to 15 mA, providing very good ca-  
pacitive drive characteristics. The MC74F623 is a non-inverting version of the  
MC74F620. These octal bus transceivers are designed for asynchronous  
two-way communication between data busses. The control function imple-  
mentation allows for maximum flexibility in timing. These devices allow data  
transmission from the A bus to the B bus or from B bus to A bus, depending  
upon the logic levels at the Enable inputs (OEBA and OEAB). The Enable in-  
puts can be used to disable the device so that the busses are effectively iso-  
lated.Thedual-enableconfigurationgivestheMC74F620andMC74F623the  
capability to store data by the simultaneous enabling of OEBA and OEAB.  
Each output reinforces its input in this transceiver configuration. Thus, when  
both control inputs are enabled and all other data sources to the two sets of  
thebuslinesareathighimpedance, bothsetsofbuslines(16inall)willremain  
at their last states.
