description

This 10-bit latch features 3-state outputs designed

specifically for driving highly capacitive or relatively low-impedance loads. It is particularly suitable for

implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The ten latches are transparent D-type latches. The SN74ALS29841 has noninverting data (D) inputs.

A buffered output-enable (OE) input can place the ten outputs in either a normal logic state (high or low logic

levels) or in a high-impedance state. The outputs also are in the high-impedance state during power-up and

power-down conditions. The outputs remain in the high-impedance state while the device is powered down. 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 interface or pullup components.

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 off.

The SN74ALS29841 is characterized for operation from 0°C to 70°C.
