SN74AS00N

Overview

The SN74AS00N is a quadruple 2-input positive-NAND gate from the Texas Instruments AS logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature range from 0°C to +70°C. The device features a propagation delay of 11 ns, with a low-level output current capability of 20 mA and a high-level output current of -400 uA. Packaged in a 14-pin PDIP format for through-hole mounting, it provides four independent NAND gates suitable for high-speed digital applications.

Feature Summary

• Contains four independent 2-input NAND logic gates
• Utilizes Advanced Schottky (AS) technology for high-speed performance
• Supports standard TTL input voltage levels
• Provides robust low-level output drive capability

Applications

• High-speed digital signal processing circuits
• General-purpose logic control systems
• Memory interface buffering
• Clock distribution networks

Procurement Notes

Verify the specific suffix 'N' confirms the 14-pin Plastic Dual In-Line Package (PDIP) and through-hole installation style. Confirm the absence of additional suffixes such as 'G4' or 'E4' if lead-free compliance is not required. Ensure the order quantity matches the tube packaging configuration typically associated with this package type. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and revision status before procurement.

Selection Notes

Select the SN74AS00N when faster switching speeds than standard LS or HC families are required but lower power consumption than S series is not the primary constraint. Compare against SN74S00N for similar speed characteristics; note that SN74AS00N offers improved noise immunity and slightly better performance metrics. Ensure the application environment stays within the specified 0°C to +70°C temperature range and utilizes a 5V supply rail compatible with the 4.5V to 5.5V operating window.

Part Context

This component belongs to the Texas Instruments SN74AS00 family, which represents the Advanced Schottky TTL logic line. This series was designed to offer higher speed performance compared to standard TTL while maintaining compatibility with existing TTL logic interfaces. The SN74AS00N specifically denotes the through-hole PDIP variant, distinguishing it from surface-mount versions like the NSR or NSRE4 packages available within the same logical function family.

Replacement Considerations

SN74S00N: Similar S-TTL series with comparable speed but different electrical characteristics. SN74LS00N: Lower speed alternative with significantly reduced power consumption. SN74HC00N: CMOS-based replacement requiring careful voltage level translation and slower switching speeds.
