SN74AS1004AN

Overview

The SN74AS1004AN is a hex inverter integrated circuit belonging to the Texas Instruments 74AS logic family. It features six independent inverters housed in a 14-pin PDIP package. The device operates within a supply voltage range of 4.5V to 5.5V and supports TTL input and output levels. Key electrical characteristics include a maximum propagation delay of 7ns at 5V with 50pF load, high-level output current of 15mA, and low-level output current of 24mA. It functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Provides six independent inverting channels for signal inversion applications
• Delivers ultra-high-speed performance with propagation delays under 7ns
• Features robust push-pull outputs capable of driving significant loads

Applications

• High-speed digital signal inversion
• Clock signal conditioning and buffering
• Logic level translation between TTL-compatible devices

Procurement Notes

Verify the specific suffix 'AN' corresponds to the 14-pin plastic DIP package when sourcing. Confirm RoHS compliance status as manufacturing standards evolve. Ensure the supplier provides official datasheets matching the SN74AS1004A series specifications. Check for availability of the E4 or G4 lead-free variants if required by environmental regulations.

Selection Notes

Select this component for designs requiring fast switching speeds and strong drive capability within standard 5V logic systems. Compare against SN74ALS1004AN for lower power consumption requirements, noting the trade-off in speed. Ensure the application environment stays within the specified 0°C to +70°C temperature range. Verify that the 15mA high-side and 24mA low-side output currents meet the fan-out requirements of connected loads.

Part Context

This part belongs to the 74AS (Advanced Schottky) family, known for superior speed compared to standard 74LS logic. It serves as a direct pin-compatible replacement for older 74S04 components while offering improved performance metrics. The hex inverter configuration allows for versatile use in complex digital circuits requiring multiple signal inversions.

Replacement Considerations

SN74ALS1004AN offers similar functionality with reduced power consumption but slower speed. SN74S04 is the legacy predecessor with comparable speed but higher power usage. SN74HC1004N provides CMOS technology with lower static power but different drive characteristics.
