Overview
The SN74AS30DR is an 8-input positive-NAND gate from Texas Instruments, part of the AS logic family. It operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal 5 V. The device features high-level output current capability of -2 mA and low-level output current of 20 mA. Propagation delays are specified as 1 ns to 5.5 ns for tPLH and 1 ns to 4.5 ns for tPHL at 5 V. It functions in the commercial temperature range of 0°C to 70°C and is housed in a 14-pin SOIC (D) package.
Feature Summary
- Contains a single 8-input positive-NAND gate performing Boolean logic Y = A · B · C · D · E · F · G · H
- Utilizes AS logic technology for high-speed switching performance
- Compatible with standard 5 V CMOS logic levels
Applications
- Digital logic circuits requiring 8-input NAND functionality
- Data processing systems utilizing TTL/CMOS compatible interfaces
- Memory address decoding applications
Procurement Notes
Verify the ordering suffix 'DR' corresponds to the SOIC package and tape-and-reel carrier format. Confirm the operating temperature range matches the application requirements of 0°C to 70°C. Ensure compatibility with 5 V supply voltages and check for RoHS compliance status in the latest packaging addendum before procurement.
Selection Notes
Select this component when an 8-input NAND gate is required in a compact surface-mount package. The AS series offers faster propagation delays compared to standard or ALS variants. Consider the 14-pin SOIC footprint for PCB layout constraints. Verify that the input and output electrical characteristics meet the specific load requirements of the target circuit design.
Part Context
This device belongs to the Texas Instruments SN74ASxx logic family, which provides advanced Schottky performance. It shares functional compatibility with other 8-input NAND gates like the SN74LS30 but offers improved speed. The SN74AS30DR is the commercial-grade version packaged in SOIC, distinct from the military-grade SN54AS30 variants.
