Features, Applications

3-State Buffer-Type Outputs Drive Bus Lines Directly Bus-Structured Pinout Provides Extra Bus-Driving Latches Necessary for Wider Address/Data Paths or Buses With Parity Buffered Control Inputs Reduce dc Loading Effects Power-Up High-Impedance State Package Options Include Plastic Small-Outline (DW) Packages and Standard Plastic (NT) 300-mil DIPs


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) 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 to 70C.
