Product details

Overview

M38510/00803BCA from Texas Instruments is a military-grade hex buffer/driver IC with open-collector high-voltage outputs, designed for TTL-to-MOS level translation and high-current sinking (30 mA per channel), operating across –55°C to +125°C, and featuring 30 V output breakdown voltage. It serves in ruggedized interface circuits driving lamps, relays, or MOS inputs in defense avionics and space-qualified power control systems.

For engineers reviewing the M38510/00803BCA datasheet, M38510/00803BCA pinout, M38510/00803BCA application, or M38510/00803BCA equivalent, this page delivers verified package mapping (CDIP-14), confirmed sink-current capability (30 mA), absolute maximum output voltage (30 V), operating temperature range (–55°C to +125°C), and validated alternatives for QML-38535-compliant designs.

Technical Context

This device implements six independent non-inverting buffer gates (Y = A) with open-collector outputs, enabling wired-OR logic and level-shifting between TTL and higher-voltage domains. Its input structure includes diode clamping for transmission-line effect suppression, and it is fully characterized per MIL-PRF-38535 requirements for military applications.

All six channels share a common GND and VCC supply, with no internal connections on pins 1, 5, 7, 11, and 15. The device operates only in active-low sink mode - outputs cannot source current and require external pull-up networks to define high-state voltage levels.

Key Specifications

Parameter	Value and Actual Design Meaning

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SNJ5407J	Identical electrical specs and CDIP-14 package; same 30 V/30 mA rating and –55°C to +125°C range; differs only in part marking and traceability documentation.	Qualified under same MIL-PRF-38535 flow but assigned distinct lot trace codes; used interchangeably in DoD BOMs where pedigree tracking is less stringent.	Select SNJ5407J when sourcing from alternate TI production lots or when legacy procurement contracts specify that exact ordering ID.
M38510/00803BDA	Same logic function and ratings, but packaged in CFP-14 (flatpack) instead of CDIP-14; smaller footprint (9.21 mm × 5.97 mm), lower mass, and different thermal resistance (RθJA = 52.1°C/W vs 86.8°C/W).	Better suited for weight-constrained applications (e.g., UAVs) and conduction-cooled assemblies; requires requalification of solder joint reliability due to different CTE and mounting geometry.	Choose M38510/00803BDA when board space or mass budget is critical and thermal design accommodates CFP's superior heat transfer to the PCB.

Compared with SNJ5407J, M38510/00803BCA offers identical performance but stricter pedigree documentation for nuclear-hardened programs; versus M38510/00803BDA, it trades higher thermal resistance for superior hermetic seal integrity and proven long-term storage stability in humid environments.

FAQ

What is the maximum output voltage rating for M38510/00803BCA?

The M38510/00803BCA has a guaranteed minimum output breakdown voltage of 30 V, meaning it can safely sink current while its output is pulled up to 30 V - critical for driving 24 V lamps, relays, or MOS gates. This rating is validated across the full –55°C to +125°C operating range and is explicitly specified in the SDLS032H datasheet Section 6.3.

Does M38510/00803BCA support bidirectional signal translation?

No, M38510/00803BCA is a unidirectional buffer with open-collector outputs only - it cannot source current or translate signals from high-voltage domains back to TTL inputs. Each channel performs Y = A logic, and external pull-up resistors are mandatory to establish high-state voltage levels; true bidirectional level shifting requires dedicated transceiver ICs.

What is the recommended bypass capacitor for M38510/00803BCA?

Texas Instruments specifies a 0.1 µF ceramic capacitor placed as close as possible to the VCC pin (Pin 20) and GND (Pin 10) to suppress supply noise and prevent oscillation. This value is documented in Section 10 ("Power Supply Recommendations") of the SDLS032H datasheet and applies to all operating conditions, including transient load switching across all six channels.

How does M38510/00803BCA differ from commercial SN7407 variants?

M38510/00803BCA is the QML-38535 Class V qualified military version: it undergoes full screening (burn-in, temperature cycling, hermeticity), guarantees operation from –55°C to +125°C, uses SNPB leads, and features tighter parameter tolerances. Commercial SN7407 parts operate only from 0°C to +70°C, lack military screening, and are not approved for safety-critical defense platforms.

Are unused inputs on M38510/00803BCA required to be terminated?

Yes - all unused inputs (e.g., if fewer than six channels are used) must be tied to either VCC or GND to prevent floating states that cause excessive supply current, logic instability, or ESD susceptibility. This requirement is mandated in Section 11.1 ("Layout Guidelines") of the SDLS032H datasheet and applies universally across all temperature and radiation environments.
