Overview
The SN74AS30D is an 8-input positive-NAND gate from the Texas Instruments 74AS series. It operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal rating of 5 V. The device provides high-level output current of -2 mA and low-level output current of 20 mA. Propagation delay ranges from 1 ns to 5 ns for tPLH and 1 ns to 4.5 ns for tPHL at 5V/50pF load conditions. It functions in commercial temperature environments from 0°C to 70°C and utilizes a 14-pin SOIC (D) package.
Feature Summary
- Performs Boolean NAND logic operations on eight distinct input signals
- Delivers high-speed switching performance characteristic of the AS logic family
- Provides robust low-level output drive capability
Applications
- Digital logic circuit design requiring multi-input NAND functionality
- High-speed data processing systems utilizing standard TTL-compatible logic levels
- General-purpose digital signal routing and control applications
Procurement Notes
Verify that the specific orderable part number matches the required package type and suffix. Confirm RoHS compliance status and lead finish specifications against the latest Package Option Addendum. Ensure the component meets the intended operating temperature range requirements before finalizing procurement decisions.
Selection Notes
Select this component when an 8-input NAND function is required alongside high-speed propagation characteristics. Compare against SN74ALS30A variants if lower power consumption is prioritized over speed. Verify that the 20 mA low-level output current meets the fan-out requirements of the connected loads.
Part Context
This device belongs to the Texas Instruments 74AS (Advanced Schottky) logic family, designed for high-speed digital applications. It serves as a standard catalog product offering enhanced performance compared to legacy 74S series devices while maintaining pin compatibility with other 74-series logic families.
Replacement Considerations
SN74ALS30A offers similar functionality with reduced power consumption but slower switching speeds. SN74LS30 provides comparable performance with significantly lower cost but higher propagation delays.
