Product details
Overview
M38510/33902BFA from Texas Instruments is a dual 4-line to 1-line data selector/multiplexer with independent strobe inputs, operating across −55°C to 125°C, supporting parallel-to-serial conversion and N-line multiplexing in military-grade systems. It features two independent 4-input sections sharing common select lines A and B, with TTL-compatible inputs and outputs, and is packaged in a 16-pin CFP (W) ceramic flatpack.
For engineers reviewing the M38510/33902BFA datasheet, M38510/33902BFA pinout, M38510/33902BFA application, or M38510/33902BFA equivalent, key selection considerations include its −55°C to 125°C temperature rating, dual-section strobe control, 7 ns typical propagation delay (tPLH/tPHL), 20 mA low-level output drive, and CFP package compatibility with high-reliability board assembly requirements.
Technical Context
The M38510/33902BFA implements two independent 4:1 multiplexer sections using TTL logic architecture with full binary decoding via internal inverters and drivers feeding AND-OR gates. Each section has dedicated strobe (G) inputs-1G and 2G-that enable cascading and selective output gating without affecting the other section.
Select inputs A and B are shared between both sections, allowing synchronized channel selection. The device supports true logic-level translation: VIH = 2 V min, VIL = 0.8 V max, VOH ≥ 2.5 V at −1 mA, VOL ≤ 0.5 V at 20 mA, and operates at VCC = 4.5–5.5 V with ICC ≤ 20 mA under recommended conditions.

Use Scenario: Selecting among multiple sensor inputs (gyro, accelerometer, GPS) for real-time telemetry uplink in flight control units. IC Role / Device Role / Timing Role: Dual-path signal routing switch that synchronizes sensor data sampling under shared address control and independent strobe arbitration. Use Value: Enables deterministic, low-latency (≤10.5 ns max tPHL) selection without software overhead or FPGA resource usage. |
Use Scenario: Multiplexing analog-to-digital converter outputs from redundant inertial measurement units (IMUs) into a central processor. IC Role / Device Role / Timing Role: Hardware-level data consolidation node with independent strobe gating per IMU channel pair. Use Value: Supports fault-isolation via individual strobe disable while maintaining continuity on the other channel - critical for fail-operational architectures. |
| Secure Communication Modem | Radar Signal Processing Backplane |
|
Use Scenario: Switching between encrypted and clear-text data paths in cryptographic modules during key exchange handshakes. IC Role / Device Role / Timing Role: Secure signal gate controlled by hardened enable signals derived from trusted execution environment (TEE) status flags. Use Value: Provides physical-layer isolation with no internal state retention - prevents side-channel leakage across paths. |

IC Role / Device Role / Timing Role: High-speed, temperature-stable multiplexer in front-end acquisition chain where jitter and skew must be minimized. Use Value: Delivers consistent 7 ns typical propagation delay across −55°C to 125°C - avoids timing drift-induced beam misalignment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4:1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54F153W | Identical electrical specs and CFP (W) package; same −55°C to 125°C rating; identical pinout and marking format. | No functional difference - direct manufacturer-equivalent with identical QML-38535 Class B qualification. | Select SNJ54F153W when sourcing from TI's standard military product line with identical traceability and test documentation. |
| M38510/33902BEA | Same logic function and temperature range, but packaged in 16-pin CDIP (J) instead of CFP (W); slightly higher thermal resistance and non-hermetic construction. | Suitable for less demanding mechanical environments (e.g., ground-based test equipment), but not for high-vibration or vacuum applications. | Choose M38510/33902BEA only if board layout accommodates DIP footprint and environmental requirements permit non-hermetic packaging. |
Compared with SNJ54F153W, M38510/33902BFA offers identical performance and qualification but differs in part numbering convention and sourcing channel; compared with M38510/33902BEA, it provides superior hermeticity and thermal cycling resilience due to the CFP package, making it mandatory for flight-critical deployments.

FAQ
What is the maximum operating temperature of the M38510/33902BFA?
The M38510/33902BFA is rated for continuous operation from −55°C to 125°C, meeting MIL-PRF-38535 Class B requirements. This specification is validated across all electrical parameters including propagation delay, output drive, and input thresholds, and applies to the CFP (W) package used for this part number.
Does the M38510/33902BFA support cascading between multiple devices?
Yes, the M38510/33902BFA supports cascading via its dedicated strobe inputs (1G and 2G). These active-low enable lines allow one device's output to control another's strobe, enabling N-line to N-line expansion without external logic. The function table confirms G = L enables Y output, making multi-stage multiplexing deterministic and glitch-free.
Is the M38510/33902BFA RoHS compliant?
No, the M38510/33902BFA uses SNPB (tin-lead) lead finish and is explicitly marked "No" for RoHS compliance in TI's packaging addendum. It is intended for high-reliability military/aerospace applications where leaded finishes are required for solder joint integrity and thermal fatigue resistance.
What is the propagation delay for address-to-output transitions on the M38510/33902BFA?
The M38510/33902BFA exhibits 7.7 ns typical tPLH and 6.6 ns typical tPHL for select inputs A or B to output Y, measured at VCC = 5 V, CL = 50 pF, and TA = 25°C. Maximum values are 10.5 ns (tPLH) and 9 ns (tPHL) across the full −55°C to 125°C range, ensuring predictable timing in synchronous digital systems.
Can the M38510/33902BFA replace commercial-grade SN74F153 devices?
No - the M38510/33902BFA is not a drop-in replacement for commercial SN74F153 devices due to its −55°C to 125°C rating, CFP packaging, and QML-38535 qualification. While functionally identical, its higher test rigor, hermetic sealing, and extended temperature validation make it unsuitable for cost-sensitive commercial designs unless those requirements are explicitly needed.
