DP8216/DP8216M/DP8226/DP8226M  
4-Bit Bidirectional Bus Transceivers  
General Description  
The DP8216/DP8216M and DP8226/DP8226M are 4-bit bi-  
directional bus drivers to use in bus oriented applications.  
The non-inverting DP8216/DP8216M and inverting  
DP8226/DP8226M drivers are provided for flexibility in sys-  
tem design.  
The DIEN input controls the direction of data flow, which is  
accomplished by forcing one of the pair of buffers into its  
high-impedance state and allowing the other to transmit its  
data. A simple two-gate circuit is used for this function.  
Features  
Y
Each buffered line of the four-bit drivers consists of two  
separate buffers that are TRI-STATE to achieve direct bus  
É
Data bus buffer driver to 8080 type CPUs  
interface and bidirectional capability. On one side of the  
driver the output of one buffer and the input of another are  
tied together (DB); this side is used to interface to the sys-  
tem side components such as memories, I/O, etc., because  
its interface is TTL compatible and it has high driver (50  
mA). On the other side of the driver the inputs and outputs  
are separated to provide maximum flexibility. Of course,  
they can be tied together so that the driver can be used to  
buffer a true bidirectional bus. The DO outputs on this side  
of the driver have a special high voltage output drive capa-  
bility so that direct interface to the 8080 type CPUs is  
achieved with an adequate amount of noise immunity.  
Y
Low input load currentÐ0.25 mA maximum  
Y
High output drive capability for driving system data  
busÐ50 mA at 0.5V  
Y
Power up-down protection  
Y
DP8216/DP8216M have non-inverting outputs  
Y
DP8226/DP8226M have inverting outputs  
Y
Output high voltage compatible with direct interface to  
MOS  
Y
TRI-STATE outputs  
Y
Advanced Schottky processing  
Y
Available in military and commercial temperature  
The CS input is a device enable. When it is ‘‘high’’ the out-  
put drivers are all forced to their high-impedance state.  
When it is a ‘‘low’’ the device is enabled and the direction of  
the data flow is determined by the DIEN input.
