description
These 9-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.
With the clock-enable (CLKEN) input low, the nine
D-type edge-triggered 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 nine Q outputs to go low, independently of the
clock.
A buffered output-enable (OE) input can be used to place the nine outputs in either a normal logic state (high
or low logic 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 bus lines
without need for interface or pullup components.
When V
CC
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 2.1 V, OE should be tied to V
CC
through a pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54ABT823 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C. The
SN74ABT823 is characterized for operation from –40
°
C to 85

C.
