(WE) and data input (Dn) to output (Qn)  
propagation delays, and the write enable  
pulse width.  
Fig.6 Waveforms showing the read address input  
(RA, RB) to output (Qn) propagation delays  
and output transition times.  
(1) HC : VM = 50%; VI = GND to VCC  
.
HCT : VM = 1.3 V; VI = GND to 3 V.  
The shaded areas indicate when the input is permitted  
to change for predictable output performance.  
The time allowed for the internal output of the latch to  
assume the state of the new data (tlatch) is important  
only when attempting to read from a location  
immediately after that location has received new data.  
This parameter is measured from the falling edge of  
WE to the rising edge of RA or RB, RE must be LOW.

hold and latch times.
