Additional Details

The PI74LPT16244AEA is typically packaged in a TSSOP (Thin Shrink Small Outline Package) or SOIC (Small Outline Integrated Circuit) package. The output enable (OE) input controls the 3-state outputs. When OE is high, the outputs are in the high-impedance state. Consult the Diodes Incorporated datasheet for detailed specifications, including propagation delays, power consumption figures, and package dimensions. Decoupling capacitors are recommended near the power supply pins for stable operation.
