description
These 8-bit bus-interface 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.
The eight flip-flops are edge-triggered D-type
flip-flops. With the clock-enable (CLKEN) input
low, the device enters data on the low-to-high
transition of the clock. Taking CLKEN high
disables the clock buffer, thus latching the outputs.
Taking the clear (CLR) input low causes the eight
Q outputs to go low independently of the clock.
Buffered output-enable (OE1, OE2, or OE3)
inputs can be used to place the eight outputs in
either a normal logic state (high or low) 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.
The output-enable inputs do 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 SN54BCT29826 is characterized for opera-
tion over the full military temperature range of
55
°C to 125°C. The SN74BCT29826 is
characterized for operation from 0
°C to 70°C.
