Detailed Description

These 10-bit latches feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The ten latches are transparent D-type latches. The 74ALS841 hasnoninverting data (D) inputs. A buffered output-enable (OE) input places the ten outputs in either a normal logic state (high or low logic levels) or a high-impedance state. In the high-impedance state, the outputs neither loadnor 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. Previously stored data can be retained or new data canbe entered while the outputs are off. The 74ALS841 is characterized for operation from 0°C to 70°C.
