DTA Data Acknowledgment (Open Drain Output). This active low output indicates that a  
data bus transfer is complete. A pull-up resistor is required at this output.  
3-5  
3-5  
STi0- ST-BUS Input 0 to 7 (Inputs). Serial data input streams. These streams have 32  
7-11  
7-11  
STi7 channels at data rates of 2.048 Mbit/s.

VDD +3.3 Volt Power Supply.  
RESET Device Reset (5v-tolerant input). This pin is only available for the 48-pin SSOP  
package. This active low input puts the MT89L85 in its reset state. It clears the internal  
counters anf registers. All ST-BUS outputs are set to the high impedance state. This  
RESET pin must be held low for a minimum of 100nsec to reset the device.

F0i Frame Pulse (Input). This input accepts and automatically identifies frame  
synchronization signals formatted according to different backplane specifications such  
as ST-BUS and GCI.  
C4i Clock (Input). 4.096 MHz serial clock for shifting data in and out of the data streams.  
15-17  
19-21  
16-18 A0-A5 Address 0 to 5 (Inputs). These lines provide the address to MT89L85 internal  
20-22  
registers.  
22  
23  
DS Data Strobe (Input). This is the input for the active high data strobe on the  
microprocessor interface. This input operates with CS to enable the internal read and  
write generation.
