description
The SN74BCT29843 features 3-state outputs
designed specifically for driving highly capacitive
or relatively low-impedance loads. It is particularly
suitable for implementing wider buffer registers,
I/O ports, bidirectional bus drivers with parity, and
working registers.
The nine latches are transparent D-type latches. When the latch-enable (LE) input is high, the Q outputs are
complementary to the noninverting data (D) inputs.
A buffered output-enable (OE) input can be used to place the nine 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 bus lines 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 SN74BCT29843 is characterized for operation from 0
°C to 70°C.
