Product details
Overview
SNJ54ALS1035J from Texas Instruments is a military-grade hex noninverting buffer IC with open-collector outputs, designed for wired-OR/AND logic interfacing in high-reliability systems. It operates across –55°C to 125°C, delivers 24 mA low-level output current (IOL), supports 5 V supply, and exhibits propagation delays as low as 2 ns (tPHL) and up to 35 ns (tPLH) under load.
For engineers reviewing the SNJ54ALS1035J datasheet, SNJ54ALS1035J pinout, SNJ54ALS1035J application, or SNJ54ALS1035J equivalent, this device is selected for level-shifting, bus driving, and TTL-compatible logic consolidation where temperature resilience and open-collector flexibility are required.
Technical Context
The SNJ54ALS1035J implements six independent noninverting buffers (Y = A) using ALS (Advanced Low-Power Schottky) bipolar technology. Each output is open-collector, requiring external pull-up resistors and enabling active-low wired-OR or active-high wired-AND configurations.
It complies with MIL-PRF-38535 Class B requirements, undergoes full parameter testing across its military temperature range, and interfaces directly with standard TTL and LS logic families. Its absolute maximum VCC of 7 V and input voltage tolerance to 7 V support robust noise margin and transient resilience.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex noninverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN54LS1035J | Lower drive strength (IOL = 8 mA), higher power (ICCL = 22 mA), slower tPLH (max 45 ns). | Suitable only for low-speed, low-load legacy systems; not recommended where 24 mA sink or <35 ns delay is required. | Select SN54LS1035J only if backward compatibility with older LS designs is mandatory and performance margins allow. |
| SNJ54ACT1035J | CMOS-based, wider VCC range (4.5–5.5 V), lower ICC (1 µA typ), but no MIL-PRF-38535 qualification. | Used in commercial/mixed-signal systems where radiation tolerance and full military screening are unnecessary. | Choose SNJ54ACT1035J for lower power and rail-to-rail noise margin, but avoid in mission-critical defense platforms requiring QML certification. |
Compared with SNJ54ALS1035J, SN54LS1035J trades speed and drive for broader legacy compatibility, while SNJ54ACT1035J offers CMOS efficiency at the cost of military-grade reliability assurance-making SNJ54ALS1035J the sole choice when both performance and QML Class B compliance are mandatory.

FAQ
What is the maximum sink current supported by each output of the SNJ54ALS1035J?
Each output of the SNJ54ALS1035J supports up to 24 mA of low-level output current (IOL) at VCC = 4.5 V and TA = 125°C, as specified in the "recommended operating conditions" table. This rating ensures reliable operation when driving multiple TTL inputs or moderate-current loads such as indicator LEDs or small relay coils, provided appropriate external pull-up resistors are used. The SNJ54ALS1035J maintains VOL ≤ 0.5 V under this condition.
Does the SNJ54ALS1035J require external pull-up resistors on its outputs?
Yes, the SNJ54ALS1035J requires external pull-up resistors on all six open-collector outputs to establish valid high-level logic states. Without pull-ups, outputs remain floating when not actively sinking current. Typical values range from 1 kΩ to 10 kΩ depending on bus capacitance, speed requirements, and load count. The SNJ54ALS1035J datasheet specifies RL = 680 Ω for switching characterization, confirming design dependency on external termination.
Is the SNJ54ALS1035J pin-compatible with the commercial SN74ALS1035N?
Yes, the SNJ54ALS1035J is pin-compatible with the SN74ALS1035N: both use identical 14-pin DIP footprints (J and N packages share same pinout), identical logic function (Y = A), and matching input/output assignments. However, SNJ54ALS1035J operates across –55°C to 125°C and is MIL-PRF-38535 qualified, whereas SN74ALS1035N is rated 0°C to 70°C and lacks military screening-making them electrically interchangeable but not environmentally substitutable.
What is the propagation delay behavior of the SNJ54ALS1035J across temperature?
The SNJ54ALS1035J exhibits worst-case propagation delays of tPHL = 14 ns and tPLH = 35 ns over its full operating range (–55°C to 125°C) at VCC = 4.5 V and CL = 50 pF. These values are specified in the "switching characteristics" table and represent maximum limits-not typicals-ensuring timing predictability in worst-case thermal and voltage conditions. At 25°C, typical delays are significantly faster (tPHL = 2 ns, tPLH = 5 ns).
Can the SNJ54ALS1035J be used in wired-AND configurations?
Yes, the SNJ54ALS1035J supports wired-AND logic when its open-collector outputs are tied together and pulled high: the combined output is high only when all individual outputs are high-impedance (i.e., all inputs are low), and goes low if any output sinks current. This behavior is explicitly documented in the device description as enabling "active-high wired-AND functions," and is commonly applied in interrupt prioritization and fault-aggregation circuits where logical conjunction of multiple signals is required.
