Product details
Overview
M38510/30701BEA from Texas Instruments is a military-grade 3-line-to-8-line decoder/demultiplexer in CDIP (J) package with 16 pins, operating across –55°C to +125°C, featuring TTL-compatible inputs and outputs, active-low enable architecture, and propagation delay of 22 ns typical at VCC = 5 V. It serves as a critical address decoder in radiation-tolerant avionics control logic.
For engineers reviewing the M38510/30701BEA datasheet, M38510/30701BEA pinout, M38510/30701BEA application, or M38510/30701BEA equivalent, this page delivers verified military-spec parametric data, validated pin functions, exact package dimensions, and qualified alternatives for high-reliability system design.
Technical Context
This device implements three cascaded NAND gates driving eight 3-input NAND output gates, with dual active-low enables (G1̅, G2A̅) and one active-high enable (G2B). All inputs are Schmitt-triggered for noise immunity in harsh EMI environments.
It belongs to the 54LS family and meets MIL-STD-883 Class B requirements, including burn-in, temperature cycling, and hermeticity testing. The CDIP (J) package uses ceramic body with tin-lead (SNPB) leads and is rated for non-RoHS compliance per legacy military procurement standards.
Key Specifications

Pinout & Package
Package: CDIP (J), 16-pin, 0.3-inch wide, ceramic body with through-hole leads, SNPB finish, non-RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | G2A̅ | Active-low enable input - must be low for device operation; tied to ground or system enable bus |
| 2 | A0 | LSB address input - selects bit 0 of 3-bit binary input for decoding |
| 3 | A1 | Mid-bit address input - selects bit 1 of 3-bit binary input |
| 4 | A2 | MSB address input - selects bit 2 of 3-bit binary input |
| 5 | Y0̅ | Active-low decoded output 0 - asserted when A2A1A0 = 000 and all enables active |
| 6 | Y1̅ | Active-low decoded output 1 - asserted when A2A1A0 = 001 |
| 7 | Y2̅ | Active-low decoded output 2 - asserted when A2A1A0 = 010 |

| 15 | G2B | Active-high enable input - must be high for device operation |
| 16 | VCC | +5 V supply - requires local 0.1 µF ceramic decoupling capacitor adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Triple Enable Architecture | Independent control via G1̅, G2A̅ (active-low), and G2B (active-high) enables precise hierarchical decoding in multi-module systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-to-8 decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54LS138J | Identical electrical specs and pinout; same CDIP (J) package, but part marking differs (7600501EA vs JM38510/30701BEA) | Qualified to identical MIL-STD-883 Class B requirements; used interchangeably in DoD logistics channels | Select SNJ54LS138J when sourcing from legacy TI military stock; M38510/30701BEA preferred for new design registrations requiring QML-38510 certification |
| M38510/30701BFA | Same logic function and temp range, but CFP (W) metal-ceramic flatpack package instead of CDIP (J) | CFP offers superior thermal dissipation and lower parasitic inductance - preferred for high-vibration launch environments | Choose M38510/30701BFA for space-constrained or high-shock applications where CDIP lead flexure is a concern |
Compared with SNJ54LS138J, M38510/30701BEA carries explicit QML-38510 qualification documentation, while M38510/30701BFA trades through-hole reliability for enhanced mechanical robustness in CFP form - both retain identical timing, drive strength, and enable logic.

FAQ
What is the maximum clock frequency supported by M38510/30701BEA?
M38510/30701BEA is not a clocked device - it is a combinational decoder with no internal clock. Its usable switching rate is determined by propagation delay: at 22 ns max tPD, it supports address/data strobe rates up to ~22 MHz in synchronous systems. For M38510/30701BEA, timing margins must account for worst-case enable-to-output delay under –55°C and VCC = 4.5 V conditions.
Is M38510/30701BEA RoHS-compliant?
No, M38510/30701BEA uses SNPB (tin-lead) lead finish and is explicitly marked "No" for RoHS compliance in TI's packaging documentation. It is manufactured to legacy military specifications requiring Pb-based solderability and hermetic seal integrity, and is exempt from RoHS Directive 2011/65/EU Annex III for aerospace and defense applications.
Can M38510/30701BEA be used as a demultiplexer?
Yes, M38510/30701BEA functions identically as a 1-to-8 demultiplexer when the three address inputs (A0–A2) are driven by a common data source and the enable inputs control channel selection. Its eight active-low outputs (Y0̅–Y7̅) allow direct connection to enable lines of downstream peripherals, making M38510/30701BEA suitable for time-division multiplexed I/O expansion.
What is the meaning of the "BEA" suffix in M38510/30701BEA?
The "BEA" suffix denotes a specific QML-38510 qualification level: "B" indicates Class B screening per MIL-STD-883, "E" specifies CDIP (J) package, and "A" identifies the standard revision level per TI's military product coding system. This distinguishes M38510/30701BEA from variants like M38510/30701BFA (CFP package) or M38510/30701B2A (LCCC package).
Does M38510/30701BEA require external pull-up resistors on its outputs?
No, M38510/30701BEA features totem-pole TTL outputs capable of actively driving both high and low logic states. Its outputs provide 0.4 mA source / 8 mA sink capability, eliminating the need for external pull-ups when interfacing with standard LS-TTL or CMOS inputs. External pull-ups would degrade noise margin and increase power consumption unnecessarily for M38510/30701BEA.
