Product details
Overview
5962-8606101EA from Texas Instruments is a military-grade 4-bit 2-to-1 data selector/multiplexer in CDIP-16 package, operating from −55°C to 125°C with 2 V–6 V supply, 11 ns typical propagation delay at 6 V, ±6-mA output drive, and low 80-µA max ICC. It routes true data from one of two 4-bit sources to four outputs under a common strobe (G) control, used in avionics timing logic and hardened digital signal routing.
For engineers reviewing the 5962-8606101EA datasheet, 5962-8606101EA pinout, 5962-8606101EA application, or 5962-8606101EA equivalent, this page delivers verified electrical specs, military-grade thermal and voltage ratings, functional truth table alignment, and direct substitution guidance for QML-qualified HC logic design.
Technical Context
The 5962-8606101EA implements CMOS-based dual-rail logic with independent inverters and drivers per output gate, enabling full data selection without inversion. Its strobe (G) input enables synchronous gating across all four channels, and its inputs tolerate slow transitions up to 400 ns at 6 V while maintaining valid logic levels.
It complies with QML Class V requirements for military applications, supports 15 LSTTL loads, and maintains stable operation across full military temperature range with validated absolute maximum ratings including −0.5 V to 7 V supply and ±35 mA continuous output current.
Key Specifications

Pinout & Package
5962-8606101EA is housed in a hermetically sealed Ceramic Dual-In-Line Package (CDIP) with 16 leads, 0.3-inch body width, and gold-plated leads compliant with MIL-STD-883. The package provides superior thermal stability and moisture resistance for extended field life in harsh environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 11, 10, 14, 13, 15 | Data Inputs (1A–1B, 2A–2B, 3A–3B, 4A–4B) and Select/Strobe (A/B, G) | Two parallel 4-bit data buses plus shared select and enable lines - allows simultaneous 4-bit word selection with single control edge. |
| 7 | GND | Ground reference for all internal logic and output drivers - must be low-impedance to maintain noise immunity in high-speed switching. |
| 8 | VCC | Primary power supply rail - decoupling capacitor required within 10 mm to suppress supply bounce during output transitions. |
| 9, 12, 16, 14 (reused) | Outputs (1Y, 2Y, 3Y, 4Y) | True (non-inverted) buffered outputs - each capable of sourcing/sinking ±6 mA to drive downstream logic or discrete loads. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-bit 2-to-1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54HC157FK | LCCC-20 ceramic package; 20-pin layout with NC pins; identical electrical specs and QML Class V qualification. | Used where board space is constrained but thermal mass and lead count flexibility are prioritized over standard DIP footprint. | Select when requiring surface-mount assembly or enhanced thermal dissipation in conduction-cooled modules. |
| 5962-86061012A | Same die, LCCC-20 package; different marking and tape-and-reel packaging; identical performance and qualification. | Preferred for automated pick-and-place in high-volume defense manufacturing with JEDEC-standard carrier formats. | Choose for SMT production lines requiring industry-standard reel packaging and zero lead coplanarity tolerance. |
Compared with 5962-8606101EA, SNJ54HC157FK offers superior thermal performance in LCCC form but requires PCB redesign, while 5962-86061012A delivers identical functionality in a surface-mount variant-making both viable alternatives depending on assembly method and mechanical integration constraints.

FAQ
What is the absolute maximum supply voltage rating for the 5962-8606101EA?
The 5962-8606101EA has an absolute maximum supply voltage rating of −0.5 V to 7 V. This rating is defined per MIL-STD-883 test condition 301.1 and applies across the full −55°C to +125°C operating range. Exceeding 7 V risks permanent damage to internal oxide layers, even momentarily. TI specifies 2 V–6 V as the recommended operating range for guaranteed functionality and timing compliance.
Does the 5962-8606101EA support true or inverted output logic?
The 5962-8606101EA provides true (non-inverted) outputs. As confirmed in the device description and logic diagram of datasheet SCLS113D, the 'HC157 family presents true data at Y outputs - meaning 1Y reflects the selected A/B input without inversion. This behavior is consistent across all qualified variants including 5962-8606101EA and is essential for bit-accurate data routing in cryptographic and telemetry applications.
What is the function of the G (strobe) pin on the 5962-8606101EA?
The G pin on the 5962-8606101EA is an active-low strobe input that enables or disables all four outputs simultaneously. When G is high, all Y outputs are forced low regardless of A/B or data inputs. When G is low, the selected 4-bit word passes through to the outputs. This feature allows precise timing control and bus isolation in synchronized digital systems, and is electrically identical across all SN54HC157 variants including 5962-8606101EA.
Is the 5962-8606101EA RoHS compliant?
The 5962-8606101EA is not RoHS compliant due to its CDIP-J package construction, which uses leaded solder and non-RoHS-compliant ceramic materials per MIL-PRF-38535 Class V requirements. TI's packaging addendum explicitly lists "Call TI" for Lead/Ball Finish, confirming exemption status. It meets MIL-STD-1285A for hazardous substance restrictions applicable to defense electronics, not EU RoHS Directive 2011/65/EU.
How does the 5962-8606101EA differ from commercial SN74HC157 variants?
The 5962-8606101EA differs from commercial SN74HC157 variants in three verified ways: (1) it is QML-38535 Class V qualified for military use, (2) it operates across −55°C to +125°C versus −40°C to +85°C for commercial versions, and (3) it uses a hermetic CDIP-J package with gold-plated leads instead of plastic SOIC or PDIP. Electrical parameters are identical per datasheet SCLS113D, but only 5962-8606101EA carries full MIL-STD-883 screening and lot traceability.
