SN74AS1004AD

Overview

The SN74AS1004AD is a hex inverter integrated circuit belonging to the Texas Instruments SN74AS series. It features six independent inverters housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum propagation delay of 4 ns at 5 V with 50 pF load. It provides high drive capability with output currents of ±48 mA and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Contains six independent single-input inverter circuits for signal inversion.
• Delivers high-speed performance with ultra-fast propagation delays characteristic of the AS logic family.
• Provides robust output drive strength suitable for demanding digital loads.

Applications

• High-speed digital signal processing systems
• Clock generation and distribution networks
• Data bus buffering and line driving

Procurement Notes

Verify the specific suffix 'ADR' against the datasheet, as it typically denotes tape-and-reel packaging, whereas 'AD' indicates tube packaging. Confirm RoHS compliance status and ensure the supplier provides valid traceability documentation. Check for lead time variations associated with surface-mount reel quantities versus standard tube packs.

Selection Notes

Select this component when high switching speed and strong current drive are required for inverting applications. Compare against SN74ALS1004 variants if lower power consumption is prioritized over speed. Ensure the 14-pin SOIC footprint matches the PCB layout constraints and verify thermal dissipation requirements for the specific enclosure type.

Part Context

This part belongs to the SN74AS (Advanced Schottky) logic family, known for superior speed compared to standard TTL. It serves as a direct functional replacement for older discrete inverter configurations in high-frequency designs. The SOIC package offers space efficiency for modern surface-mount assembly processes.

Replacement Considerations

SN74AS1004ANSR is a parameter-equivalent alternative available from Texas Instruments in tape-and-reel format.
