16-bit transceiver/register with dual enable; 3-state
74ALVCH16652
FUNCTION TABLE
See note 1.
Notes
1.
H = HIGH voltage level;
L = LOW voltage level;
X = don’t care;
↑
= LOW-to-HIGH.
The data output functions may be enabled or disabled by various signals at the nOE
AB
and nOE
BA
inputs. Data input
functions are always enabled, i.e., data at the bus inputs will be stored on every LOW-to-HIGH transition on the clock
inputs.
