description
These 10-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, bidirectional bus drivers with
parity, and working registers.
On the positive transition of the clock the Q outputs
will follow the D inputs.
A buffered output enable (OE) input can be used
to place the ten outputs in either a normal logic
state (high or low level) 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 increased drive
provide the capability to drive the bus lines in a
bus-organized system without need for interface
or pull-up components.
The output enable (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 54ACT11821 is characterized for operation over the full military temperature range of –55
°C to 125°C. The
74ACT11821 is characterized for operation form – 40
°C to 85°C.
