DESCRIPTION/ORDERING INFORMATION
This 16-bit universal bus driver is designed for 1.65-V
to 3.6-V V
CC
operation.
Data
flow
from
A
to
output-enable (OE) input. The device operates in the
transparent mode when the latch-enable (LE) input is
low. When LE is high, the A data is latched if the
clock (CLK) input is held at a high or low logic level. If
LE is high, the A data is stored in the latch/flip-flop on
the low-to-high transition of CLK. When OE is high,
the outputs are in the high-impedance state.
