These 10-bit bus-interface latches 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 ten latches of the ′BCT29841 are transparent

D-type latches. When the latch-enable (LE) input

ishigh, theQoutputswillfollowthedata(D)inputs.

When LE is taken low, the Q outputs are latched

at the levels that were set up at the 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-impedancestate.

In the high-impedance state, the outputs neither

load nor drive the bus lines significantly. The

high-impedancestateandincreaseddriveprovide

the capability to drive bus lines without need for

interface or pullup components.

NC – No internal connection

The output enable (OE) does not affect the internal operation of the latches. Old data can be retained or new

data can be entered while the outputs are in the high-impedance state.

The SN54BCT29841 is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74BCT29841 is characterized for operation from 0°C to 70°C.
