description  
GND  
These 8-bit D-type transparent latches feature  
3-state outputs designed specifically for driving  
highly capacitive or relatively low-impedance  
loads. They are particularly suitable for  
implementing buffer registers, I/O ports,  
bidirectional bus drivers, and working registers.  
While latch-enable (LE) input is high, the Q outputs follow the complements of the data (D) inputs. When LE is  
taken low, the Q outputs are latched at the inverses of the levels set up at the D inputs. The SN74ALS533A and  
SN74AS533A are functionally equivalent to the SN74ALS373A and SN74AS373, except for having inverted  
outputs.  
A buffered output-enable (OE) input places the eight outputs in either a normal logic state (high or low logic  
levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines  
significantly. The high-impedance state and increased drive provide the capability to drive bus lines without  
interface or pullup components.  
OE does not affect the internal operations of the latches. Old data can be retained or new data can be entered  
while the outputs are off.  
The SN74ALS533A and SN74AS533A are characterized for operation from 0°C to 70°C.
