SN74AS95AD

Shift Registers Overview

The SN74AS95AD is a high-speed 4-bit serial-in/parallel-out shift register from Texas Instruments' Advanced Schottky (AS) logic family. It operates on a single supply voltage ranging from 4.5 V to 5.5 V and features an asynchronous clear input for immediate data reset. The device utilizes a 14-pin Small Outline Integrated Circuit (SOIC) package designed for surface-mount technology. It supports unidirectional data shifting triggered by the positive edge of the clock signal, ensuring reliable performance in digital logic applications within standard commercial temperature ranges.

Shift Registers Feature Summary

• Advanced Schottky logic architecture providing high switching speeds with low power consumption
• Asynchronous clear function allows immediate resetting of all flip-flop outputs regardless of clock state
• Serial-to-parallel conversion capability for efficient data interface management
• Positive-edge clock triggering ensures precise synchronization with system timing

Shift Registers Applications

• Digital logic circuits requiring serial-to-parallel data conversion
• High-speed data processing systems utilizing TTL-compatible interfaces
• General-purpose shift register implementations in embedded hardware

Shift Registers Procurement Notes

Verify the specific suffix 'AD' confirms the SOIC-14 surface-mount package variant. Confirm the manufacturer is Texas Instruments to ensure compatibility with AS-series specifications. Check for end-of-life notifications or discontinuance notices, as older logic families may have limited long-term availability. Ensure the component meets RoHS compliance requirements if mandated by your assembly standards.

Shift Registers Selection Notes

Select this component when a 4-bit shift register with parallel output is required in a space-constrained design. The AS series offers superior speed compared to standard LS or ALS counterparts. Consider the SOIC-14 footprint for PCB layout compatibility. Verify that the 4.5V to 5.5V operating range aligns with the target system's power supply rails before integration.

Shift Registers Part Context

This part belongs to the Texas Instruments SN74ASxx series, which represents the Advanced Schottky logic family. This family was engineered to provide faster propagation delays than previous generations while maintaining lower power dissipation. The SN74AS95AD specifically addresses applications needing rapid serial data handling within standard TTL voltage levels.

Shift Registers Replacement Considerations

Compatible substitutes include other SN74AS95 variants with different packaging options, such as the SN74AS95N for through-hole DIP applications. Cross-referencing with equivalent 4-bit shift registers from other manufacturers requires careful verification of pinouts and electrical characteristics to ensure functional parity.
