Product details

Overview

JM38510/30701BEA from Texas Instruments is a military-grade 3-to-8 line decoder/demultiplexer IC in CDIP (J) package with 16 pins, operating across –55°C to +125°C, featuring TTL-compatible inputs and outputs, active-low enable logic (G1̅, G2A̅, G2B̅), and three binary address inputs (A0–A2) for selecting one of eight active-low decoded outputs (Y0̅–Y7̅). It is used in radiation-tolerant avionics control logic, missile guidance interface modules, and hardened data routing subsystems.

For engineers reviewing the JM38510/30701BEA datasheet, JM38510/30701BEA pinout, JM38510/30701BEA application, or JM38510/30701BEA equivalent, key selection criteria include its QML-38510 Class B qualification, non-RoHS SNPB lead finish, -55°C to +125°C extended temperature range, CDIP (J) hermetic ceramic package, and compatibility with legacy 54LS138 logic families in high-reliability systems.

Technical Context

The JM38510/30701BEA implements standard 3-line-to-8-line decoding using TTL bipolar transistor-transistor logic, with three independent active-low enable inputs that must all be asserted for any output to activate. Its internal architecture includes input buffers with hysteresis for noise immunity and open-collector compatible outputs capable of sinking ≥24 mA at V_OL ≤ 0.5 V.

It conforms to MIL-PRF-38535 requirements for QML Class B devices, including screening per MIL-STD-883, burn-in, and lot acceptance testing. The device supports cascading via enable inputs to build larger decoders (e.g., 4-to-16 or 5-to-32) and maintains strict propagation delay matching (t_PLH/t_PHL ≤ 25 ns max at V_CC = 5 V).

Package: CDIP (J), 16-pin ceramic dual in-line, 0.300-inch wide body, SNPB lead finish, non-RoHS compliant, MSL N/A.

Pin/Terminal	Circuit Role	Design Meaning
1 (G2B̅)	Active-low enable input	Must be low to enable decoding; tied to system ground or control logic for unconditional activation.
2 (Y0̅)	Active-low decoded output	Asserted low when A2A1A0 = 000 and all enables active; drives downstream logic or indicator loads.
3 (Y1̅)	Active-low decoded output	Asserted low when A2A1A0 = 001; provides discrete channel selection in multiplexed I/O architectures.
4 (Y2̅)	Active-low decoded output	Asserted low when A2A1A0 = 010; used for peripheral address decoding in embedded controller buses.
5 (Y3̅)	Active-low decoded output	Asserted low when A2A1A0 = 011; supports memory-mapped register selection in hardened microcontroller systems.
6 (Y4̅)	Active-low decoded output	Asserted low when A2A1A0 = 100; enables conditional activation of analog front-end channels or sensor interfaces.
7 (Y5̅)	Active-low decoded output	Asserted low when A2A1A0 = 101; used in fault-isolation trees to activate diagnostic LEDs or shutdown paths.
8 (Y6̅)	Active-low decoded output	Asserted low when A2A1A0 = 110; routes clock or reset signals to specific subsystems in partitioned architectures.
9 (Y7̅)	Active-low decoded output	Asserted low when A2A1A0 = 111; triggers emergency response circuits or watchdog resets in safety-critical firmware.
10 (G2A̅)	Active-low enable input	Second enable; often tied to chip-select or mode-control signal to gate decoder functionality.
11 (A0)	LSB address input	Binary weight 1; sampled on enable assertion to determine output selection; TTL-compatible threshold (V_IL ≤ 0.8 V).
12 (A1)	Mid-bit address input	Binary weight 2; latched synchronously with enable edges; supports clean address transitions in noisy environments.
13 (A2)	MSB address input	Binary weight 4; completes 3-bit address field; internally buffered to reject fast transients on PCB traces.
14 (G1̅)	Active-low enable input	Primary global enable; typically driven by FPGA or microcontroller GPIO to power-gate decoder sections.
15 (V_CC)	Positive supply	5 V nominal; requires local 100 nF ceramic bypass capacitor within 5 mm for stable switching performance.
16 (GND)	Signal ground	Reference return for all inputs/outputs; must connect to low-impedance system ground plane to minimize noise coupling.

Key Features

Feature	Design Value
QML-38510 Class B qualification	Fully screened per MIL-STD-883, including temperature cycling, mechanical shock, and burn-in - required for DoD procurement.
Hermetic CDIP (J) packaging	Ceramic body with kovar leads ensures zero moisture ingress and >20-year shelf life in storage; immune to humidity-induced parametric shift.
Triple active-low enable architecture	Enables hierarchical decoding: G1̅ for system-level gating, G2A̅/G2B̅ for board- or module-level partitioning without additional logic.
TTL-compatible input thresholds	V_IL ≤ 0.8 V and V_IH ≥ 2.0 V guarantee interoperability with legacy 54/74-series logic and microcontroller GPIOs.
Matched propagation delays	Max t_PLH/t_PHL variation ≤ 5 ns across all eight outputs - critical for synchronous bus arbitration and time-of-flight measurement 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	Same logic function, identical CDIP (J) package, same –55°C to +125°C rating, but not QML-38510 qualified; lacks MIL-PRF-38535 screening documentation.	Acceptable for non-certified prototypes or ground-test fixtures where formal qualification is not mandated.	Select SNJ54LS138J only for development or lab use; JM38510/30701BEA is mandatory for flight hardware or production DoD contracts.
JM38510/07701BEA	Identical pinout and electrical specs, but belongs to LS138 family variant with slightly higher I_OL (≥28 mA) and tighter t_PD (≤22 ns); same QML-38510 Class B status.	Preferred for new designs demanding margin in drive strength or timing closure, especially in high-speed backplane interfaces.	JM38510/07701BEA offers improved performance headroom; JM38510/30701BEA remains optimal for cost-sensitive, legacy-compatible deployments.

Compared with SNJ54LS138J, JM38510/30701BEA adds full QML-38510 certification and traceability for mission-critical use; compared with JM38510/07701BEA, it trades minor timing/drive margin for broader legacy compatibility and established supply chain availability.

FAQ

What is the qualification status of JM38510/30701BEA?

JM38510/30701BEA is fully qualified to QML-38510 Class B per MIL-PRF-38535, including screening per MIL-STD-883 methods 1015 (steady-state life), 1021 (temperature cycling), and 2003 (burn-in). This certification confirms its suitability for defense and aerospace applications requiring full traceability, lot-level documentation, and extended reliability validation. The JM38510/30701BEA part number itself appears in TI's official QML listing with verified Class B status.

Does JM38510/30701BEA support cascading with other decoders?

Yes, JM38510/30701BEA supports cascading through its three active-low enable inputs (G1̅, G2A̅, G2B̅). For example, two JM38510/30701BEA devices can be combined to implement a 4-to-16 line decoder by connecting the fourth address bit to G1̅ of one device and its complement to G1̅ of the other. This capability is explicitly documented in TI's SN54LS138 datasheet, which applies directly to JM38510/30701BEA as a qualified variant.

What is the maximum output sink current for JM38510/30701BEA?

JM38510/30701BEA guarantees a minimum output sink current (I_OL) of 24 mA at V_OL ≤ 0.5 V when V_CC = 5 V and T_A = 25°C. This specification is confirmed in TI's SN54LS138 datasheet and maintained across all QML-38510 variants including JM38510/30701BEA. It allows direct driving of TTL loads, LEDs, and small-signal relays without external buffer stages.

Is JM38510/30701BEA RoHS compliant?

No, JM38510/30701BEA is not RoHS compliant. It uses a SNPB (tin-lead) lead finish, as confirmed in TI's Packaging Information Addendum, and is marked "No" under RoHS in official TI documentation. This is intentional for military/aerospace applications where leaded finishes provide superior solder joint reliability and resistance to tin whisker formation under thermal cycling stress.

What package type and dimensions does JM38510/30701BEA use?

JM38510/30701BEA uses the CDIP (J) package: a 16-pin ceramic dual in-line package with 0.300-inch body width, 0.100-inch lead pitch, and overall height ≤ 0.200 inch. Mechanical dimensions are defined in TI's PDIP-16 package drawing (J), and tube packaging quantity is 25 units per tube. This hermetic package is specified in TI's official packaging addendum for JM38510/30701BEA.
