Product details
Overview
M38510/07906BEA from Texas Instruments is a military-grade quadruple 2-line to 1-line data selector/multiplexer in CDIP (J) package with 16 pins, operating across –55°C to +125°C, supporting TTL-level logic control and data routing in hardened avionics and defense systems.
For engineers reviewing the M38510/07906BEA datasheet, M38510/07906BEA pinout, M38510/07906BEA application, or M38510/07906BEA equivalent, this device delivers deterministic signal selection with guaranteed propagation delay ≤25 ns, fan-out of 10 LSTTL loads, and compatibility with SN54LS257B logic family timing and voltage thresholds.
Technical Context
This device implements four independent 2:1 multiplexers sharing common select (S) and enable (G̅) inputs, each selecting between two data inputs (A/B) to drive one output (Y). All logic operates at standard TTL voltage levels (VIH = 2.0 V min, VIL = 0.8 V max).
It uses bipolar Schottky-clamped transistor technology for high-speed switching and low power dissipation (ICC = 24 mA max at VCC = 5.5 V), with guaranteed operation under extended temperature and radiation-hardened conditions per MIL-PRF-38535 Class B requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Quadruple 2-line to 1-line data selector/multiplexer - routes four independent data pairs using shared control lines |
| Logic Family | LS-TTL - compatible with SN54LS257B timing, drive strength, and noise margins |
| Propagation Delay | 25 ns max (tPLH/tPHL at VCC = 5.5 V, CL = 15 pF) - ensures predictable timing in synchronous digital subsystems |
| Supply Voltage Range | 4.5 V to 5.5 V - supports stable operation under regulated military power rails |
| Operating Temperature | –55°C to +125°C - qualified for airborne, space, and ground vehicle mission-critical environments |
| Fan-Out | 10 LSTTL loads - drives standard TTL inputs without buffering in dense logic arrays |
| Package | CDIP (J), 16-pin - hermetically sealed ceramic dual in-line package for moisture resistance and thermal stability |
Pinout & Package
CDIP (J) package: 16-pin ceramic dual in-line, 0.300-inch body width, through-hole mounting, hermetic seal, SNPB (tin-lead) lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 9, 10, 12, 13 | Data Inputs (IA0–IA3, IB0–IB3) | Eight independent data inputs grouped as four A/B pairs for multiplexing |
| 3, 6, 11, 14 | Outputs (Y0–Y3) | Four buffered, active-high outputs corresponding to selected inputs |
| 7 | GND | Ground reference for all logic and power connections |
| 15 | VCC | +5 V supply input - must be decoupled locally per MIL-STD-883 requirement |
| 16 | S | Common select line - high selects IBx, low selects IAx for all four channels |
| 8 | G̅ | Active-low enable - output disabled (high-impedance) when G̅ = high |
Key Features
| Feature | Design Value |
|---|---|
| QML-38535 Class B qualification | Manufactured and tested per MIL-PRF-38535 for high-reliability defense/aerospace use |
| Hermetic CDIP packaging | Prevents moisture ingress and enables long-term reliability in harsh environmental profiles |
| Guaranteed AC/DC parametrics over full temp range | All timing and voltage specs validated from –55°C to +125°C, not just room temperature |
| Compatible with SN54LS257B logic family | Drop-in functional and timing replacement for legacy SN54LS257BJ in existing designs |
| Low power consumption | 24 mA max ICC at VCC = 5.5 V - reduces thermal load in densely packed modules |

FAQ
What is the exact logic function of M38510/07906BEA?
M38510/07906BEA implements four independent 2:1 data selectors sharing common S (select) and G̅ (enable) inputs. Each channel routes either IAx or IBx to Yx based on S state when G̅ is low. It matches the SN54LS257B truth table and timing behavior exactly.
Is M38510/07906BEA pin-compatible with commercial SN74LS257B variants?
No - M38510/07906BEA uses CDIP (J) packaging with 0.300-inch row spacing, while SN74LS257B typically uses PDIP (N) or SOIC (D) packages with different pin pitches and thermal characteristics. Electrical pin functions match, but mechanical layout requires redesign.
Does M38510/07906BEA support 3.3 V operation?
No - M38510/07906BEA is specified only for 4.5 V to 5.5 V operation per its LS-TTL design. It lacks 3.3 V logic level compatibility and will not meet VIH/VIL thresholds or timing specs below 4.5 V.
What is the meaning of "BEA" in M38510/07906BEA?
"BEA" is the JAN/MIL-STD-1835 suffix indicating CDIP (J) package, Class B QML-38535 qualification, and standard military temperature range (–55°C to +125°C). It distinguishes this variant from CFP (W) or LCCC (FK) versions of the same base device.
How does M38510/07906BEA differ from M38510/07906BFA?
M38510/07906BEA uses CDIP (J) packaging, while M38510/07906BFA uses CFP (W) flatpack. Both share identical logic function, temperature range, and QML-38535 Class B qualification, but differ in thermal resistance, mounting method, and board footprint.
