Overview
The SN74ALS30ADBE4 is an 8-input positive-NAND gate from the Texas Instruments ALS logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum load capacitance of 50 pF. The device features a low-level output current capability of 8 mA and is housed in a 14-pin SOIC package. It is designed for commercial temperature operation, functioning reliably between 0°C and +70°C.
Feature Summary
- Provides high-speed switching performance characteristic of the Advanced Low-Power Schottky (ALS) logic family.
- Integrates eight inputs into a single NAND gate function within a compact surface-mount package.
Applications
- Digital logic circuit design requiring multi-input decision making
- Data acquisition systems utilizing standard TTL-compatible interfaces
- Microprocessor-based control units
Procurement Notes
Verify that the ordering suffix 'E4' corresponds to lead-free packaging and RoHS compliance as specified by Texas Instruments. Confirm the package designation matches the required board layout dimensions. Ensure the component meets the specific commercial temperature grade requirements for the intended application environment before finalizing procurement.
Selection Notes
Select this component when an 8-input NAND function is required with ALS speed and power characteristics. It serves as a direct replacement for the non-lead-free SN74ALS30ADB variant. Consider the 14-SOIC footprint constraints and ensure the design accommodates the 50 pF load capacitance specification for proper signal integrity.
Part Context
This part belongs to the SN74ALS30 series of 8-input NAND gates manufactured by Texas Instruments. It is part of the broader 74ALS logic family, which offers improved speed and lower power consumption compared to standard LS logic. The device is widely used in digital electronics where multiple input conditions must be evaluated simultaneously.
Replacement Considerations
The SN74ALS30ADB is the non-lead-free equivalent. Verify pinout compatibility and electrical specifications against other 8-input NAND gates from different manufacturers if cross-brand substitution is necessary.
