Additional Details

The TC74VHC9541FT typically comes in a TSSOP (Thin Shrink Small Outline Package) or SOIC (Small Outline Integrated Circuit) package. The 3-state outputs can be disabled, allowing the device to be effectively removed from the circuit. This is useful for implementing bus arbitration and multiplexing schemes. The device is designed to be compatible with other CMOS and TTL logic families. Proper decoupling capacitors should be used to minimize noise and ensure stable operation. The datasheet provides detailed information on electrical characteristics, timing diagrams, and application circuits. It's important to observe the recommended operating conditions and power supply voltage to ensure reliable performance.
