Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific revision level (Rev. A) against your design requirements. Confirm that the TSSOP-16 footprint matches your PCB layout exactly. Ensure the 4.5V to 5.5V supply voltage constraints are met in your power design. Check for any specific handling precautions related to CMOS inputs during storage and assembly processes.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent decoding channels are required in a compact surface-mount package. It is appropriate for designs needing fast switching speeds with standard 5V logic levels. Consider the 24mA drive capability for direct interfacing with moderate load conditions without additional buffering.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Texas Instruments ACT series of advanced CMOS logic devices. The ACT series combines the speed of TTL logic with the low power consumption of CMOS technology. The 74ACT11139 specifically addresses needs for multi-channel decoding in space-constrained electronic assemblies.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for pin-compatible alternatives within the same ACT family. Verify electrical characteristics such as propagation delay and output current if substituting with other manufacturers' parts.
