What are the key features of SN74ALS05ANS?
- 6-channel hex inverter with open-collector outputs enabling wired-AND bus configurations and mixed-voltage level shifting
- Advanced Low-power Schottky (ALS) technology delivering propagation delay of approximately 7 ns at 5 V supply
- Wide fan-out capability supporting up to 20 standard TTL loads per output for large bus driving
- 14-pin DIP package for easy prototyping and through-hole PCB assembly in industrial applications
What is SN74ALS05ANS used for?
The SN74ALS05ANS is commonly used in TTL-level signal inversion, bus driver circuits, and open-collector wired-AND logic implementations in industrial control systems and embedded microcontroller interfaces. Its open-collector outputs allow direct interfacing to LED drivers, relay coils, and mixed-voltage logic systems operating between 2 V and 5.5 V. It is also found in vintage and legacy digital system designs requiring pin-compatible ALS logic replacements.

Frequently Asked Questions
What propagation delay can I expect from the SN74ALS05ANS and how does it compare to standard TTL?
The SN74ALS05ANS offers a typical propagation delay of approximately 7 ns at a 5 V supply, which is significantly faster than standard 74LS05 devices rated at around 15 ns. This makes the ALS variant better suited for high-speed digital logic designs operating at bus frequencies above 20 MHz where timing margin is critical.
Which voltage rail and load conditions are supported when using SN74ALS05ANS open-collector outputs?
The SN74ALS05ANS open-collector outputs support a maximum collector voltage (VOH pull-up) of 5.5 V and can sink up to 24 mA per output at the LOW state, making them compatible with driving LEDs, small relays, and multiple TTL inputs. The supply voltage is 5 V ±10%, and up to 20 standard TTL unit loads can be driven per output channel.
When should a designer choose SN74ALS05ANS over SN74HCT05 for an open-collector inverter application?
Choose SN74ALS05ANS over SN74HCT05 when the design requires direct TTL-compatible input thresholds and must interface with existing bipolar TTL logic families at 5 V. The ALS family provides better current-drive capability at 24 mA sink current versus HCT's 4 mA, making SN74ALS05ANS preferable for driving bus lines or loads that demand higher output sink current.
How does the 14-pin DIP package of SN74ALS05ANS benefit prototyping and through-hole PCB assembly?
The 14-pin DIP package with 2.54 mm pin pitch allows direct insertion into standard breadboards and through-hole PCB footprints, simplifying prototyping of TTL logic circuits. Compared to surface-mount packages, the 14-pin DIP has a body width of 6.35 mm providing mechanical robustness and ease of hand soldering during evaluation and small-batch production runs.
