The 'AC16374 are 16-bit edge-triggered D-type flip-flops with
3-state outputs designed specifically for driving highly capacitive
or relatively low-impedance loads. They are particularly suitable for
implementing buffer registers, I/O ports, bidirectional bus drivers,
and working registers.
The 'AC16374 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
A buffered output-enable
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
affect the internal operations of the flip-flop. Old data can be
retained or new data can be entered while the outputs are in the
The 74AC16374 is packaged in TI's shrink small-outline package,
which provides twice the I/O pin count and functionality of standard
small-outline packages in the same printed-circuit-board area.
The 54AC16374 is characterized for operation over the full
military temperature range of -55°C to 125°C. The 74AC16374
is characterized for operation from -40°C to 85°C.
