description
These octal buffers utilize the latest advanced
low-power Schottky technology. The ’ALS465A
and ’ALS466A have a two-input active-low AND
enable gate controlling all eight data buffers. The
’ALS467A and ’ALS468A have two separate
active-low enable inputs each controlling four data
buffers. In each case, a high level on any G places
the affected outputs at high impedance.
