Overview
The SN74ALS05ADR is a hex inverter with open-collector outputs belonging to the Texas Instruments Advanced Low-Power Schottky (ALS) logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 18 ns. The device provides a low-level output current of 8 mA and a high-level output current of -400 uA. Packaged in a surface-mount SOIC-14 format, it supports an operating temperature range from 0°C to +70°C.
Feature Summary
- Hex inverter configuration with open-collector outputs for flexible interfacing
- Advanced Low-Power Schottky technology ensuring reduced power consumption
- High noise immunity characteristics inherent to the ALS logic series
Applications
- General-purpose digital signal inversion
- Open-collector bus line driving applications
- Interface circuits requiring wired-OR logic capabilities
Procurement Notes
Verify the specific suffix 'ADR' corresponds to the SOIC-14 tape-and-reel packaging variant when sourcing. Confirm that the required operating environment falls within the specified commercial temperature range of 0°C to +70°C. Ensure supply voltage constraints between 4.5 V and 5.5 V are strictly maintained during system design to guarantee correct logical operation and prevent device damage.
Selection Notes
Select this component when designing systems requiring multiple inverted signals with open-collector drive capability. The ALS series offers a balance of speed and power efficiency suitable for standard TTL-compatible environments. Consider the SOIC-14 package dimensions for PCB layout constraints. Verify that the 8 mA sink current meets the load requirements of the connected circuitry without exceeding thermal limits.
Part Context
This part belongs to the broader SN74ALSxx series of logic integrated circuits manufactured by Texas Instruments. The ALS family represents an evolution of earlier Schottky technologies, providing improved power-delay product performance. It serves as a standard solution for discrete logic functions in industrial and consumer electronic control systems requiring reliable TTL-level compatibility.
Replacement Considerations
Compatible substitutes include the SN74ALS05AD (tube version) and other hex inverters within the same ALS family. Cross-reference pinouts and electrical specifications carefully before substitution.
