3-STATE Octal Bus Transceiver  
General Description  
Features  
These octal bus transceivers are designed for asynchro-  
nous two-way communication between data buses. The  
control function implementation minimizes external timing  
requirements.  
Bi-Directional bus transceiver in a high-density 20-pin  
package  
3-STATE outputs drive bus lines directly  
PNP inputs reduce DC loading on bus lines  
Hysteresis at bus inputs improve noise margins  
Typical propagation delay times, port-to-port 8 ns  
Typical enable/disable times 17 ns  
The device allows data transmission from the A Bus to the  
B Bus or from the B Bus to the A Bus depending upon the  
logic level at the direction control (DIR) input. The enable  
input (G) can be used to disable the device so that the  
buses are effectively isolated.  
IOL (sink current)  
24 mA  
IOH (source current)  
15 mA
