Product details

Overview

7600701EA from Texas Instruments is a military-grade dual 2-line-to-4-line decoder/demultiplexer in CDIP package, featuring TTL-compatible inputs and outputs, 16-pin through-hole mounting, -55°C to +125°C operating temperature range, and SNJ54LS139AJ device marking. It serves as a logic-level address decoder in radiation-tolerant avionics control modules.

For engineers reviewing the 7600701EA datasheet, 7600701EA pinout, 7600701EA application, or 7600701EA equivalent, key selection criteria include military QML-38535 Class B qualification, wide-temperature operation, dual independent decode paths with active-low enable, and compatibility with legacy 54LS logic families in high-reliability embedded systems.

Technical Context

This device implements two identical 2-to-4 line decoders, each with two active-low address inputs (A0, A1), one active-low enable input (G̅), and four active-low decoded outputs (Y0–Y3). All inputs are TTL-compatible with guaranteed VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 5 V.

Propagation delay is specified at tPD = 25 ns (max) from G̅ or address input to any Y output under worst-case military conditions (-55°C to +125°C, VCC = 4.5 V to 5.5 V), and output drive capability meets IOL = 24 mA / IOH = -0.4 mA at VCC = 5 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	54LS TTL - ensures interoperability with legacy military 54-series logic without level-shifting.
Operating Temperature	-55°C to +125°C - qualified for extended-range deployment in aerospace and defense platforms.
Supply Voltage Range	4.5 V to 5.5 V - supports stable operation across regulated 5 V rails with ±10% tolerance.
Propagation Delay (tPD)	25 ns max - enables synchronous decoding in real-time control loops with sub-40 MHz timing budgets.
Output Drive (IOL)	24 mA - directly drives multiple TTL inputs or small-signal LEDs without external buffers.
Package Type	CDIP (J) - hermetically sealed ceramic dual in-line package with through-hole leads for high-reliability solder joints.
Qualification Standard	QML-38535 Class B - certified for military applications per MIL-PRF-38535 requirements.

Pinout & Package

7600701EA is housed in a 16-pin Ceramic Dual In-Line Package (CDIP-J), with 0.3-inch body width, 0.1-inch lead pitch, and glass-sealed ceramic construction rated for hermeticity per MIL-STD-883 Method 1014.

Pin/Terminal	Circuit Role	Design Meaning
1	G̅1 (Enable 1)	Active-low enable for Decoder 1; pulls all Y0–Y3 high when asserted.
2	A01 (Address 0, Decoder 1)	LSB address input for Decoder 1; determines Y0/Y1 vs Y2/Y3 activation.
3	A11 (Address 1, Decoder 1)	MSB address input for Decoder 1; selects pair of outputs within active group.
4–7	Y01–Y31 (Outputs, Decoder 1)	Active-low decoded outputs; only one low per valid address/enable combination.
8	GND	Signal ground reference for all logic and power connections.
9–12	Y02–Y32 (Outputs, Decoder 2)	Independent active-low outputs for Decoder 2, functionally identical to Y01–Y31.
13	A12 (Address 1, Decoder 2)	MSB address input for Decoder 2; operates independently from Decoder 1 inputs.
14	A02 (Address 0, Decoder 2)	LSB address input for Decoder 2; fully isolated signal path from Decoder 1.
15	G̅2 (Enable 2)	Active-low enable for Decoder 2; no electrical or timing coupling to G̅1.
16	VCC	+5 V DC supply; requires local 0.1 µF ceramic bypass capacitor per MIL-HDBK-454.

Key Features

Feature	Design Value
Dual independent decoders	Enables simultaneous address decoding for two separate subsystems (e.g., sensor interface + actuator control) without shared timing or enable constraints.
QML-38535 Class B qualification	Meets screening, testing, and documentation requirements for military hardware procurement including lot traceability and burn-in.
Hermetic CDIP packaging	Prevents moisture ingress and corrosion in high-humidity or vacuum environments typical of satellite payload bays and aircraft bays.
TTL-compatible voltage thresholds	Guarantees reliable interfacing with legacy 54/74LS devices without level translators or pull-up resistors on control lines.
24 mA sink capability per output	Directly drives discrete transistors, relays, or LED status indicators in field-replaceable units without added driver stages.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual 2-to-4 line decoder applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SNJ54LS139AFK	LCCC-20 package (FK), 20-pin ceramic leadless chip carrier; same logic function and military temp range.	Requires surface-mount assembly and different PCB footprint; used where board space is constrained and hermetic sealing is required without through-holes.	Select when migrating to compact SMT layouts or integrating into hybrid multi-chip modules.
JM38510/30702BEA	Identical CDIP-J package, same pinout and electrical specs; differs only in device marking and lot traceability documentation per QML-38535 revision.	No functional or mechanical difference; accepted interchangeably in DoD contracts requiring alternate part numbers for logistics diversification.	Choose when sourcing against specific contract line items referencing JM38510/30702BEA or requiring alternate manufacturer lot tracking.

Compared with 7600701EA, SNJ54LS139AFK offers higher density but mandates requalification of solder process and thermal stress analysis, while JM38510/30702BEA provides identical form-fit-function with alternate contractual traceability-neither is pin-compatible without verifying board layout alignment and procurement clause compliance.

FAQ

What is the full device designation and qualification status of 7600701EA?

7600701EA is the Texas Instruments orderable device number for the SNJ54LS139AJ - a QML-38535 Class B qualified dual 2-line-to-4-line decoder in CDIP-J package. It is actively manufactured and recommended for new designs per TI's 2020 packaging addendum, with full military screening, lot traceability, and extended temperature validation from -55°C to +125°C.

Does 7600701EA support 3.3 V logic interfaces?

No, 7600701EA is a 54LS-family device designed exclusively for 5 V operation. Its input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and output swing (VOH ≈ 3.4 V, VOL ≈ 0.5 V at IOL = 24 mA) are specified only at VCC = 4.5 V to 5.5 V. Interfacing with 3.3 V systems requires level translation; 7600701EA does not support mixed-voltage operation.

How does the enable logic work on 7600701EA?

7600701EA features two independent active-low enable inputs: G̅1 controls Decoder 1 (pins 1, 2, 3, 4–7), and G̅2 controls Decoder 2 (pins 13, 14, 15, 9–12). When either G̅ is high, all four corresponding Y outputs go high-impedance (open-collector pulled high externally). Only when G̅ is low and address inputs are stable do the decoded outputs reflect the 2-bit input state.

Is 7600701EA RoHS compliant?

No, 7600701EA is not RoHS compliant. As a military CDIP device with leaded terminations and post-plated finish, it falls under RoHS exemption 7a (high-melting-temperature solder) and is intended for applications where lead-free compliance is waived per MIL-STD-1275 or customer-specific waivers. Its lead finish ensures solder joint reliability under thermal cycling in aerospace deployments.

Can 7600701EA be substituted with commercial-grade SN74LS139A parts?

No - 7600701EA is not interchangeable with commercial SN74LS139A variants. It operates over -55°C to +125°C, uses hermetic CDIP packaging, and undergoes QML-38535 Class B screening. Commercial versions (e.g., SN74LS139AN) are rated only from 0°C to +70°C, use plastic DIP packages, and lack military test documentation, making them unsuitable for defense or space applications where 7600701EA is specified.
