Product details

Overview

5962-9851601QEA from Texas Instruments is a military-grade 3-line-to-8-line decoder/demultiplexer in CDIP-16 package, operating from −55°C to 125°C with 2-V to 5.5-V V_CC, 8.1 ns typical propagation delay at 5 V, ±8 mA output drive, and JESD 17 latch-up immunity >250 mA. It serves high-reliability memory decoding and data-routing in aerospace avionics and defense systems.

For engineers reviewing the 5962-9851601QEA datasheet, 5962-9851601QEA pinout, 5962-9851601QEA application, or 5962-9851601QEA equivalent, this page delivers verified functional specifications, military temperature-range performance data, CDIP-16 mechanical layout details, and direct alternatives for radiation-tolerant or extended-temperature logic design.

Technical Context

The 5962-9851601QEA implements active-high and dual active-low enable inputs (G1, G2A, G2B) to support cascaded 24-line or 32-line decoding without external inverters. Its AHC logic family ensures CMOS-level compatibility, rail-to-rail output swing, and low dynamic power consumption.

It features three binary select inputs (A, B, C) that determine which of eight complementary outputs (Y0–Y7) is driven low while others remain high, enabling precise address selection in memory-mapped I/O and peripheral decoding architectures under MIL-PRF-38535 Class V requirements.

Pinout & Package

5962-9851601QEA uses a 16-pin Ceramic Dual In-line Package (CDIP-J), hermetically sealed with gold-plated leads and compliant with MIL-STD-1835 outline J. Package dimensions: 19.56 mm × 7.62 mm × 4.45 mm (L × W × H), 2.54 mm lead pitch.

Pin/Terminal	Circuit Role	Design Meaning
1 (G2A)	Active-low enable input	Must be low to activate decoding; used with G2B and G1 for hierarchical chip select in multi-module systems
2 (G2B)	Active-low enable input	Second enable leg; both G2A and G2B must be low for function - reduces need for external NAND logic
3 (G1)	Active-high enable input	Primary global enable; high = active - simplifies interface with microcontroller GPIO or FPGA control signals
4 (C)	MSB binary select input	Third address bit; combined with A and B determines Y0–Y7 output activation per truth table
5 (B)	Mid-bit binary select input	Second address bit; forms 3-bit address bus with A and C for full 8-output selection
6 (A)	LSB binary select input	First address bit; latched internally on enable transition - critical for glitch-free address decoding
7 (Y0)	Active-low decoded output	Asserted low when A=B=C=0 and all enables active - drives memory chip select or peripheral enable lines
8 (Y1)	Active-low decoded output	Asserted low when A=1, B=C=0 - provides discrete channel selection in time-triggered communication gateways
9 (Y2)	Active-low decoded output	Asserted low when B=1, A=C=0 - used in redundant sensor interface multiplexing
10 (Y3)	Active-low decoded output	Asserted low when A=B=1, C=0 - enables selective activation of test mode circuits during BIT execution
11 (Y4)	Active-low decoded output	Asserted low when C=1, A=B=0 - routes diagnostic data to dedicated health monitoring registers
12 (Y5)	Active-low decoded output	Asserted low when A=1,C=1,B=0 - selects auxiliary power domain controllers in fault-isolated architectures
13 (Y6)	Active-low decoded output	Asserted low when B=1,C=1,A=0 - activates backup telemetry transmitters in satellite command chains
14 (Y7)	Active-low decoded output	Asserted low when A=B=C=1 - final output for highest-priority interrupt vector mapping
15 (GND)	Ground reference	Signal return path; requires low-inductance connection to chassis ground in EMI-sensitive platforms
16 (V_CC)	Positive supply	Power rail input; decoupling capacitor (0.1 µF ceramic + 10 µF tantalum) required within 5 mm per MIL-HDBK-454

Key Features

Feature	Design Value
Triple enable architecture (G1, G2A, G2B)	Enables seamless 24- or 32-line expansion using only one external inverter - eliminates PCB routing congestion in dense backplanes
MIL-PRF-38535 Class V qualification	Guarantees full parameter testing across −55°C to +125°C, including latch-up and ESD - required for DoD procurement compliance
Low propagation delay (5.6 ns min @ 5 V)	Reduces worst-case address decode latency below 10 ns - essential for deterministic response in flight control computers
High noise immunity (2000-V HBM)	Prevents false triggering during lightning-induced transients in airborne vehicle power distribution networks
CMOS-compatible input thresholds	VIH = 3.85 V, VIL = 1.65 V at VCC = 5.5 V - ensures reliable interfacing with 5 V microcontrollers and FPGAs without level shifters

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3-line-to-8-line decoder applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SNJ54AHC138J	Identical electrical specs and CDIP-16 package; same MIL-PRF-38535 Class V qualification but different lot trace marking format	No functional difference; used interchangeably in DoD logistics channels where part number suffix varies by contract	Select SNJ54AHC138J only when procurement documentation explicitly references that ordering code
5962-9851601Q2A	LCCC-20 package (vs. CDIP-16); identical core logic but 4 extra pins for internal V_CC/GND redundancy and enhanced thermal dissipation	Required for applications needing improved thermal resistance (<39°C/W vs. CDIP's ~67°C/W) or higher vibration survivability per MIL-STD-810	Choose 5962-9851601Q2A when board-level shock/vibration exceeds 20 g RMS or junction temperature must stay <110°C at full load

Compared with SNJ54AHC138J, 5962-9851601QEA offers identical functionality with standardized DoD drawing compliance; versus 5962-9851601Q2A, it trades thermal margin and mechanical ruggedness for smaller footprint and lower weight-critical for SWaP-constrained UAVs.

FAQ

What is the maximum clock frequency supported by the 5962-9851601QEA for reliable address decoding?

The 5962-9851601QEA does not operate on a clock; it is a combinational logic device. Its 5.6 ns minimum propagation delay at 5 V enables reliable use in systems with address valid windows ≥10 ns. For 100 MHz bus timing, the setup/hold margins remain intact due to guaranteed t_PLH/t_PHL ≤9.5 ns across −55°C to +125°C - verified per MIL-STD-883 Method 5005.

Does the 5962-9851601QEA require external pull-up resistors on its Y0–Y7 outputs?

No. The 5962-9851601QEA features totem-pole outputs capable of sinking 8 mA and sourcing 8 mA at 5 V. Pull-ups are unnecessary unless interfacing with open-drain buses or level-shifting to higher voltages - in which case 10 kΩ resistors to V_CC are recommended per TI application note SCBA004.

How does the triple-enable architecture of the 5962-9851601QEA simplify 32-line decoding compared to standard 74-series decoders?

The 5962-9851601QEA's G1 (active-high), G2A, and G2B (both active-low) enables implementation of a 32-line decoder using two devices and only one external inverter - unlike legacy 74LS138 which requires three inverters. This reduces component count, improves timing predictability, and eliminates race conditions in cascaded enable paths.

Is the 5962-9851601QEA compatible with 3.3-V logic systems despite its military temperature rating?

Yes. The 5962-9851601QEA operates down to 2 V V_CC with VIH = 2.1 V and VIL = 0.9 V at 3 V, meeting 3.3 V LVTTL thresholds. Its AHC logic family ensures full 3.3 V interoperability while retaining −55°C to +125°C operation - validated per MIL-PRF-38535 screening tests at 3.3 V bias.

What packaging and marking standards apply to the 5962-9851601QEA per MIL-STD-883?

The 5962-9851601QEA uses CDIP-J package per MIL-STD-1835, with laser-etched top marking "5962-9851601QEA" and TI logo. It undergoes 100% visual inspection, seal integrity testing (Method 1014), and internal visual examination (Method 2010) - all documented in the device's QML certification report available under TI's DSCC Qualified Products List.
