5962-8768301EA

Overview

The Texas Instruments 5962-8768301EA is a military-grade, high-speed CMOS quad 2-input NAND buffer and driver. It belongs to the SN54ALS1000A series, designed for demanding applications requiring fast switching speeds and low power consumption. The device features four independent logic gates with standard TTL-compatible inputs and active pull-up outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended industrial temperature range from -55°C to +125°C. Packaged in a ceramic dual-in-line (CDIP) format, it ensures reliability in harsh environments.

Feature Summary

• High-speed CMOS technology providing significantly faster propagation delays compared to standard LS logic families while maintaining lower power dissipation.
• Military-grade construction utilizing hermetic ceramic packaging to ensure long-term stability and resistance to extreme environmental conditions.
• Active pull-up output structure that improves noise immunity and driving capability for high-capacitive loads in complex digital systems.

Applications

• High-performance military computing systems and avionics data buses
• Ruggedized industrial control interfaces requiring extended temperature tolerance
• Spacecraft telemetry and communication subsystems

Procurement Notes

Verify the specific suffix EA confirms the military grade and ceramic CDIP package configuration against the official datasheet. Ensure compatibility with existing board layouts regarding pinout dimensions and thermal management requirements for hermetic packages. Confirm availability through authorized distributors as this component may have limited production runs or require special ordering procedures due to its specialized nature.

Selection Notes

Select this component when system design requires the speed advantages of ALS logic combined with the environmental robustness of military-grade hardware. It serves as a direct functional replacement for other SN54ALS1000 variants in legacy designs. Consider the physical size and mounting constraints of the CDIP package during PCB layout. Validate input voltage levels to ensure proper logic threshold compliance across the full operating temperature range.

Part Context

This part number falls under the Texas Instruments SN54 family of high-speed logic devices. The SN54 designation indicates military qualification standards, distinguishing it from commercial SN74 counterparts. The ALS series represents Advanced Low-power Schottky technology, balancing speed and power efficiency. This specific iteration provides quad NAND functionality essential for complex gate logic implementations in critical infrastructure.

Replacement Considerations

Direct substitutes include other SN54ALS1000A variants with compatible suffixes indicating equivalent performance and packaging. Cross-reference pinouts and electrical characteristics carefully when considering alternative manufacturers' equivalents to ensure signal integrity and timing margins are maintained.
