description
These 18-bit flip-flops feature 3-state outputs
designed specifically for driving highly-capacitive
or relatively low-impedance loads. They are
particularly suitable for implementing wider buffer
registers, I/O ports, parity bus interfacing, and
working registers.
The ’ACT16823 can be used as two 9-bit flip-flops
or one 18-bit flip-flop. With the clock-enable
(CLKEN) input low, the D-type flip-flops enter data
on the low-to-high transitions of the clock. Taking
CLKEN high disables the clock buffer, thus
latching the outputs. Taking the clear (CLR) input
low causes the Q outputs to go low independently
of the clock.
A buffered output-enable (OE) input can be used to place the 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.
OE does not affect the internal operation of the flip-flops. Old data can be retained or new data can be entered
while the outputs are in the high-impedance state.
The 74ACT16823 is packaged in theTI 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 54ACT16823 is characterized for operation over the full military temperature range of 55
°
C to 125
°
C. The
74ACT16823 is characterized for operation from –40
°
C to 85
°
