Product details
Overview
M38510/32403SSA from Texas Instruments is a military-grade octal buffer and line driver with 3-state outputs, designed for memory address bus driving and bus-oriented signal transmission in high-reliability systems. It features dual 4-bit channels, active-low output-enable (G) control per channel, PNP input structure reducing DC loading, 400-mV noise margin, and compatibility with 3.3-V or 5-V logic inputs. It operates across –55°C to 125°C and drives terminated lines down to 133 Ω.
For engineers reviewing the M38510/32403SSA datasheet, M38510/32403SSA pinout, M38510/32403SSA application, or M38510/32403SSA equivalent, key selection criteria include its MIL-PRF-38535 qualification, 15 ns max propagation delay at 5 V, 3-state bus-driving capability, dual independent enable control, and compatibility with mixed-voltage logic interfaces in avionics and defense computing.
Technical Context
The M38510/32403SSA implements two independent 4-bit non-inverting buffer sections, each with separate active-low output-enable (1G and 2G) inputs. Its PNP input stage minimizes DC loading on upstream drivers, while built-in hysteresis improves noise immunity on bus lines. The device supports bidirectional bus isolation via high-impedance output states controlled by G inputs.
It uses TTL-compatible Schottky transistor logic (S-type) architecture, delivering higher drive strength than LS variants - up to 64 mA low-level output current (IOL), enabling reliable signal transmission over longer PCB traces or unterminated buses. All parameters are 100% tested per MIL-PRF-38535 requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN54LS244J | LS-family variant; lower drive (24 mA IOL), slower (15 ns tpd), no MIL-PRF-38535 qualification | Suitable only for commercial-temperature, non-safety-critical board-level buffering | Select when cost sensitivity outweighs environmental ruggedness and radiation assurance needs |
| M38510/32402SSA | Inverting output logic (vs. non-inverting); identical package, temperature range, and MIL spec compliance | Required where system-level signal polarity inversion is needed in address decoding paths | Choose for designs requiring inverted Y outputs while maintaining full military qualification and pinout compatibility |
Compared with SN54LS244J, M38510/32403SSA delivers 2.7× higher output drive and guaranteed military screening, making it suitable for harsh-environment bus driving; versus M38510/32402SSA, it provides non-inverting signal path integrity essential for memory address mirroring without additional logic inversion.

FAQ
What is the maximum operating temperature range for the M38510/32403SSA?
The M38510/32403SSA is rated for operation from –55°C to +125°C. This extended temperature range is verified per MIL-PRF-38535 requirements and supports deployment in jet engine bays, radar transmitter enclosures, and satellite payload compartments where ambient thermal extremes occur.
Does the M38510/32403SSA support 3.3-V logic inputs?
Yes, the M38510/32403SSA accepts 3.3-V logic inputs reliably. Its inputs are tolerant down to 2 V and compatible with both 3.3-V and 5-V logic families, enabling seamless integration into mixed-voltage systems such as FPGA-based controllers interfacing with legacy 5-V peripherals - a key feature confirmed in TI's SDLS144D datasheet.
What is the output drive capability of the M38510/32403SSA?
The M38510/32403SSA delivers up to 64 mA of low-level output current (IOL) and –15 mA of high-level output current (IOH). This S-series drive strength allows it to reliably drive terminated lines down to 133 Ω and sustain signal integrity across long PCB traces typical in military backplane architectures.
Is the M38510/32403SSA pin-compatible with commercial SN54S244 devices?
Yes, the M38510/32403SSA uses the same CFP-20 pinout as SN54S244J and shares identical terminal functions, including dual active-low G inputs and non-inverting A→Y mapping. However, M38510/32403SSA undergoes full MIL-PRF-38535 screening, whereas SN54S244J does not.
How does the hysteresis feature benefit system design with the M38510/32403SSA?
The M38510/32403SSA incorporates 0.2–0.4 V of input hysteresis, which increases noise margin by 400 mV on bus lines. This directly improves immunity to EMI in electrically noisy environments like aircraft cockpits or radar shelters, reducing false triggering and ensuring deterministic logic transitions without external Schmitt-trigger add-ons.
