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.
