SN74AS10DR

Overview

The SN74AS10DR is a triple 3-input positive-NAND gate integrated circuit manufactured by Texas Instruments. It belongs to the AS (Advanced Schottky) logic series, utilizing bipolar technology for high-speed performance. The device is housed in a 14-pin SOIC surface-mount package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from 0°C to +70°C. Key electrical characteristics include a propagation delay of 5.5 ns, a low-level output current of 20 mA, and a high-level output current of -2 mA.

Feature Summary

• Provides three independent 3-input NAND logic functions within a single package.
• Utilizes Advanced Schottky (AS) bipolar technology to achieve high switching speeds with reduced propagation delay.
• Designed for standard 5 V digital systems with robust output drive capabilities.

Applications

• High-speed digital signal processing circuits requiring fast logical inversion.
• Computer peripheral interfaces and data transmission lines.
• General-purpose logic control in industrial automation systems.

Procurement Notes

Verify the specific suffix 'DR' indicates the tape-and-reel packaging format when ordering. Confirm that the application environment remains within the specified 0°C to +70°C commercial temperature range. Ensure the power supply voltage does not exceed the maximum rating of 5.5 V to prevent device damage. Cross-reference the manufacturer part number with official Texas Instruments documentation to ensure authenticity and correct revision level.

Selection Notes

Select this component when a triple 3-input NAND function is required in a compact surface-mount form factor. The AS series offers superior speed compared to standard LS or ALS logic families. Consider the 14-pin SOIC footprint for PCB layout compatibility. Evaluate the 5.5 ns propagation delay against system timing requirements to ensure adequate signal integrity at target clock frequencies.

Part Context

This device is part of the SN74ASxx family of advanced Schottky logic ICs from Texas Instruments. The family is characterized by its use of bipolar transistor technology, which provides faster switching speeds than CMOS alternatives while maintaining reasonable power consumption. The SN74AS10 specifically addresses applications needing multiple 3-input NAND gates without consuming excessive board space.

Replacement Considerations

Compatible substitutes include the SN74AS10N (DIP package) and SN74AS10D (tube package). Verify pinout compatibility and electrical specifications before substitution. Alternative logic families such as SN74LS10 may be used if higher speed is not critical, though performance will differ significantly.
