SN74AS1004ANSR

Overview

The SN74AS1004ANSR is a hex inverter from the Texas Instruments SN74AS series, housed in a 14-SOIC surface-mount package. It operates on a single supply voltage ranging from 4.5 V to 5.5 V. The device features six independent inverting channels with TTL-compatible inputs and outputs. Key electrical specifications include a propagation delay of 4 ns, a high-level output current of -48 mA, and a low-level output current of 48 mA. It functions within an ambient temperature range of 0°C to +70°C.

Feature Summary

• Provides six independent inverting logic channels for signal inversion applications.
• Features high-current drive capability suitable for direct interfacing with TTL loads.
• Utilizes Schottky-clamped bipolar technology to achieve fast switching speeds.

Applications

• Clock signal generation and conditioning circuits
• Data bus line drivers requiring signal inversion
• Combinational logic implementation in digital systems

Procurement Notes

Verify the component authenticity by checking the manufacturer's marking code against official documentation. Confirm that the SOIC-14 package dimensions match the specified mechanical drawing. Ensure the operating environment remains within the defined temperature limits to maintain performance reliability. Cross-reference the datasheet revision to confirm compatibility with specific design requirements.

Selection Notes

Select this component when high-speed inversion is required alongside significant load driving capabilities. The AS series offers superior speed compared to standard TTL variants while maintaining compatible logic levels. Consider the thermal dissipation characteristics of the SOIC package during PCB layout planning. Evaluate power consumption constraints as bipolar technologies typically draw more quiescent current than CMOS alternatives.

Part Context

This part belongs to the SN74AS family, representing Advanced Schottky TTL logic. It serves as a high-performance alternative to standard 74S series devices, offering faster propagation delays without sacrificing noise immunity. The SN74AS1004 specifically provides hex inverter functionality, commonly used for creating complementary signals or inverting data lines in complex digital architectures.

Replacement Considerations

SN74AS1004ADR is a parameter-equivalent alternative available from Texas Instruments. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement package variant meets the physical footprint requirements of the existing design.
