FEATURES
DESCRIPTION
The 74ALVCH16841 has two 10-bit D-type latch featuring separate
D-type inputs for each latch and 3-State outputs for bus oriented
applications. The two sections of each register are controlled
independently by the latch enable (nLE) and output enable (nOE)
control gates.
When nOE is LOW, the data in the registers appears at the outputs.
When nOE is High the outputs are in High-impedance OFF state.
Operation of the nOE input does not affect the state of the flip-flops.
The 74ALVCH16841 has active bus hold circuitry which is provided
to hold unused or floating data inputs at a valid logic level. This
feature eliminates the need for external pull-up or pull-down
resistors.
