1.8V CMOS 16-BIT EDGE-
TRIGGERED D-TYPE FLIP-FLOP
WITH 3-STATE OUTPUTS
DESCRIPTION:
This 16-bit edge-triggered D-type flip-flop is built using advanced CMOS
technology. The AUC16374 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,theQoutputsoftheflip-floptakeonthelogiclevelsatthedata
(D) inputs.
OEcanbeusedtoplacetheeightoutputsineitheranormallogicstate(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
needforinterfaceorpullupcomponents.
OE doesnotaffecttheinternaloperation
of the flip-flop. Old data can be retained or new data can be entered while the
outputs are in the high-impedance state.
This device is fully specified for partial power-down applications using IOFF.
The IOFF circuitry disables the outputs, preventing damaging current backflow
through the device when it is powered down.
To ensure the high-impedance state during power up or power down,
