54FCT573  
Octal D-Type Latch with TRI-STATE® Outputs  
General Description  
The ’FCT573 is an octal latch with buffered common Latch  
Enable (LE) and buffered common Output Enable (OE) in-  
puts.  
Features  
n Inputs and outputs on opposite sides of package allow  
easy interface with microprocessors  
n Useful as input or output port for microprocessors  
n TTL input and output level compatible  
n CMOS power consumption  
This device is functionally identical to the ’FCT373 but has  
different pinouts.  
n Functionally identical to ’FCT373  
n TRI-STATE outputs for bus interfacing  
n Output sink capability of 32 mA, source capability of  
12 mA  
n Standard Microcircuit Drawing (SMD) 5962-8863901
