5962-8688802DA

Overview

The Texas Instruments part number 5962-8688802DA is a military-grade quadruple 2-input positive-NAND buffer and driver. It belongs to the SN54ALS1000A series, utilizing Advanced Low-Power Schottky (ALS) TTL technology to achieve high-speed operation with reduced power consumption. The device features four independent NAND gates, each providing two inputs. Designed for harsh environments, it operates within an extended temperature range of -55°C to +125°C and supports a supply voltage range of 4.75 V to 5.25 V. Typical propagation delay is 13 ns at 5 V, with a typical low-level output current of 24 mA and high-level output current of -8 mA.

Feature Summary

• Advanced Low-Power Schottky (ALS) TTL architecture ensures faster switching speeds compared to standard LS logic while maintaining lower power dissipation.
• Military-grade qualification allows reliable operation across extreme environmental conditions, specifically supporting temperatures from -55°C to +125°C.
• Quadruple configuration integrates four independent 2-input NAND gates into a single package, optimizing board space for complex logic applications.

Applications

• Military avionics systems requiring robust digital logic processing under extreme thermal stress.
• Spacecraft communication interfaces utilizing high-reliability NAND gate arrays.
• Radar signal processing units where fast propagation delays are critical for timing accuracy.

Procurement Notes

Verify the specific suffix DA against the manufacturer's official datasheet to confirm pinout compatibility and packaging details. Ensure that the procurement channel provides traceability documentation suitable for military or aerospace specifications. Confirm RoHS status and lead times directly with authorized distributors, as availability for this specific military variant may be limited.

Selection Notes

Select this component when designing systems that require the speed of ALS technology combined with the power efficiency improvements over standard TTL. It is appropriate for applications needing four independent NAND functions in a single package. Consider the CPAK-16 package constraints during PCB layout. Verify that the system power supply remains strictly within the 4.75 V to 5.25 V range to ensure correct logic levels.

Part Context

This part is a military version of the commercial SN54ALS1000A quad NAND buffer. The 5962 prefix indicates it is a direct-from-drawings (DFD) part manufactured to MIL-SPEC requirements. It serves as a drop-in replacement for other military-grade ALS NAND buffers in legacy defense electronics, offering improved performance over older SSI logic families.

Replacement Considerations

Compatible substitutes include other military-grade ALS quad NAND buffers such as the SN54ALS1000A in equivalent military packaging. Verify pin-to-pin compatibility before substitution. Alternative technologies like FET Logic (FEL) or CMOS may offer lower power but different speed characteristics.
