Product details
Overview
M38510/30901BEA from Texas Instruments is a military-grade 8-line to 1-line data selector/multiplexer in CDIP (J) package with 16 pins, operating across -55°C to +125°C, featuring TTL-compatible inputs and outputs, propagation delay of 22 ns max at VCC = 5 V, and fan-out capability of 10 LSTTL loads. It serves as a critical signal routing component in hardened digital control logic for aerospace flight computers.
For engineers reviewing the M38510/30901BEA datasheet, M38510/30901BEA pinout, M38510/30901BEA application, or M38510/30901BEA equivalent, this page delivers verified military-spec timing, packaging, functional equivalence, and sourcing details specific to the CDIP (J)-packaged variant with SNPB lead finish and full MIL-PRF-38535 Class B qualification.
Technical Context
The M38510/30901BEA implements standard 74LS151 logic functionality with three select inputs (S0–S2), one enable input (E̅), eight data inputs (I0–I7), and complementary outputs (Y and Y̅). Its internal architecture uses TTL bipolar transistor logic with Schottky-clamped outputs to ensure noise immunity and stable switching under wide temperature extremes.
All timing parameters-including tPLH = 22 ns and tPHL = 22 ns (max) at VCC = 5 V, CL = 15 pF-are specified over the full -55°C to +125°C range and validated per MIL-STD-883 methods 3011, 3012, and 3015. Input thresholds meet VIH = 2.0 V min and VIL = 0.8 V max, ensuring robust compatibility with legacy 5-V TTL systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-to-1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54LS151J | Identical logic function, same CDIP (J) package, identical -55°C to +125°C rating, but marked per JAN specification rather than M38510 prefix | No functional difference; used interchangeably in DoD contracts where either JAN or M38510 nomenclature is accepted | Select SNJ54LS151J if procurement documentation requires JAN designation or when cross-referencing legacy drawings citing "JAN54LS151" |
| M38510/07901BEA | Same family, CDIP (J) package, identical pinout and timing, but configured as dual 4-to-1 multiplexer (two independent 4-input sections) | Requires redesign of select logic and routing; suitable only when two independent 4-input paths are needed instead of one 8-input path | Choose M38510/07901BEA only when system architecture mandates separate control of two data domains with shared enable logic |
Compared with SNJ54LS151J, M38510/30901BEA offers identical performance and form factor but reflects updated M38510 nomenclature aligned with current DoD procurement standards; versus M38510/07901BEA, it provides single-path 8-input selection rather than dual 4-input capability-making it optimal for centralized signal arbitration in compact control units.

FAQ
What is the full military specification compliance status of M38510/30901BEA?
M38510/30901BEA is fully compliant with MIL-PRF-38535 Class B, including screening per Method 5005, burn-in per Method 5007, and lot acceptance testing per Method 5009. It meets all electrical, environmental, and reliability requirements for use in Level 1 and Level 2 defense systems per DoD standards. The device carries full QML certification and is listed on the Qualified Products List (QPL) for 54LS151 devices.
Does M38510/30901BEA support hot-swap or live-insertion in backplane systems?
No, M38510/30901BEA does not support hot-swap operation. Its TTL input structure lacks bus-hold or power-up/down protection circuitry, and the CDIP package has no controlled-impedance leads. Insertion must occur only with system power off and proper ESD precautions. For hot-swap applications, consider modern radiation-tolerant alternatives with explicit hot-swap support-not M38510/30901BEA.
Can M38510/30901BEA be operated at 3.3 V supply voltage?
No, M38510/30901BEA is strictly a 5-V TTL device with VCC specification of 4.5 V to 5.5 V. Operation below 4.5 V violates its absolute maximum ratings and results in undefined logic states, increased propagation delay, and potential latch-up. It is incompatible with 3.3-V systems unless interfaced via level translators such as SN74LVC8T245.
Is there a RoHS-compliant version of M38510/30901BEA available?
No RoHS-compliant version exists for M38510/30901BEA. Its SNPB (tin-lead) lead finish and CDIP (J) package are intentionally non-RoHS to maintain solder joint integrity under thermal cycling and mechanical shock per MIL-STD-883. TI does not offer a Pb-free variant of this exact military-spec part number; RoHS alternatives like SN74LS151N operate only from 0°C to +70°C and lack QML qualification.
What is the maximum clock frequency supported by M38510/30901BEA when used in a synchronous data selector configuration?
M38510/30901BEA is not a clocked device and has no internal clock; it operates asynchronously. Its maximum usable data rate depends on propagation delay and setup/hold times of upstream drivers. With tPD = 22 ns max, it supports reliable operation up to approximately 20 MHz in static-select configurations, assuming clean edges and proper termination. For higher rates, verify timing margins using actual board-level signal integrity analysis-not M38510/30901BEA datasheet alone.
