DESCRIPTION/ORDERING INFORMATION
This 16-bit edge-triggered D-type flip-flop is designed
for 1.65-V to 3.6-V V_CC operation.
The SN74ALVCH162374 is particularly suitable for
implementing buffer registers, I/O ports, bidirectional
bus drivers, and working registers. It can be used as
two 8-bit flip-flops or one 16-bit flip-flop. On the
positive transition of the clock (CLK) input, the Q
outputs of the flip-flop take on the logic levels set up
at the data (D) inputs.
The output-enable (OE) input can be used to place
the eight outputs in either a normal logic state (high
or low logic levels) or a high-impedance state. In the
high-impedance state, the outputs neither load nor
drive the bus lines significantly. The high-impedance
state and the increased drive provide the capability to
drive bus lines without need for interface or pullup
components. OE does not affect internal operations
of the flip-flop. Old data can be retained or new data
can be entered while the outputs are in the
high-impedance state.
