DM74LS573  
Octal D-Type Latch with 3-STATE Outputs  
General Description  
The DM74LS573 is a high speed octal latch with buffered  
common Latch Enable (LE) and buffered common Output  
Enable (OE) inputs.  
Features  
Inputs and outputs on opposite sides of package allow-  
ing easy interface with microprocessors  
Useful as input or output port for microprocessors  
Functionally identical to DM74LS373  
This device is functionally identical to the DM74LS373, but  
has different pinouts.  
Input clamp diodes limit high speed termination effects  
Fully TTL and CMOS compatible
