Ithas the samehigh speed performance ofLSTTL combined with trueCMOSlow power consumption.
This device is a 3 to 8 line decoder with latches onthe three address inputs.
When GLgoes from low to high, the address present at the select inputs (A, B and C) is stored in the latches.
As long as GLremains high no address changes will be recognized.
Output enable pins G1 and G2, ...
