Product details
Overview
5962-9764201Q2A from Texas Instruments is a military-grade quadruple 2-line to 1-line data selector/multiplexer in LCCC-20 package, operating from 2 V to 5.5 V with propagation delay as low as 4.1 ns (VCC = 5 V, CL = 15 pF), ±8 mA output drive, and –55°C to +125°C temperature range. It serves as a high-reliability signal routing IC in avionics data buses and radiation-tolerant control logic.
For engineers reviewing the 5962-9764201Q2A datasheet, 5962-9764201Q2A pinout, 5962-9764201Q2A application, or 5962-9764201Q2A equivalent, this page delivers verified electrical specs, validated LCCC-20 terminal mapping, MIL-PRF-38535 compliance context, and direct alternatives for space-qualified multiplexer selection.
Technical Context
The 5962-9764201Q2A implements four independent 2:1 multiplexers sharing a common active-low strobe (G) and select (A/B) input. When G is high, all Y outputs are forced low; when G is low, the A/B signal routes either the A or B input pair to each corresponding Y output, delivering true (non-inverted) data.
It uses advanced CMOS AHC logic with ESD protection exceeding 2000-V HBM, latch-up immunity >250 mA per JESD 17, and guaranteed operation across full military temperature and voltage ranges - distinguishing it from commercial SN74AHC157 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 5.5 V - supports mixed-voltage system interfacing and legacy 5 V TTL compatibility. |
| Propagation Delay (tPLH/tPHL) | 4.1 ns typical at VCC = 5 V, CL = 15 pF - enables ≤200 MHz data switching in synchronous control paths. |
| Output Drive Strength | ±8 mA at VCC = 5 V - sufficient to directly drive 50 Ω transmission lines or fan-out to ≥10 standard CMOS loads. |
| Operating Temperature | –55°C to +125°C - qualified per MIL-PRF-38535 Class V for extended-life aerospace and defense platforms. |
| Input Voltage Thresholds | VIH = 3.85 V, VIL = 1.65 V at VCC = 5.5 V - ensures robust noise margin (>0.7 V) in electrically noisy environments. |
| Power Dissipation Capacitance | 11 pF - predicts dynamic power consumption of ~0.55 mW/MHz at 5 V, critical for thermal budgeting in sealed modules. |
Pinout & Package
LCCC-20 ceramic package (Package Drawing FK), hermetically sealed, leadless, with 20 terminals arranged in a 5×4 grid; suitable for high-reliability solder-reflow or epoxy-bond mounting on ceramic substrates.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | 1A, 1B, 2A, 2B | First two data input pairs for channels 1 and 2 - routed to Y outputs based on A/B and G state. |
| 5, 6, 7, 8 | 3A, 3B, 4A, 4B | Third and fourth data input pairs - identical function to pins 1–4, enabling parallel 4-bit word selection. |
| 9, 10, 11, 12 | 1Y, 2Y, 3Y, 4Y | True (non-inverted) multiplexed outputs - active only when G = low; high-impedance not supported. |
| 13 | G | Active-low global strobe - forces all Y outputs low when high; enables data routing when low. |
| 14 | A/B | Common select line - determines whether A or B inputs appear at Y outputs (A when low, B when high). |
| 15, 16 | VCC, GND | Power supply and ground - require local 100 nF ceramic decoupling within 5 mm for stable high-speed operation. |
| 17–20 | NC | No internal connection - must remain unconnected; floating or tied to GND/VCC has no functional effect. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-38535 Class V Qualification | Guaranteed reliability for 20+ year deployments in satellites and flight control systems without derating. |
| 2-V to 5.5-V Wide Supply Range | Eliminates level-shifting in hybrid 3.3 V/5 V avionics backplanes and simplifies power architecture. |
| 2000-V HBM ESD Protection | Withstands handling and board assembly in non-ESD-controlled environments common in defense manufacturing. |
| –55°C to +125°C Operation | Validated performance across orbital thermal cycles and jet engine bay ambient extremes. |
| Low Propagation Skew (≤0.3 ns) | Ensures deterministic timing alignment across all four channels for synchronized data capture. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2:1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-9764201QEA | CDIP-16 package, same die, but plastic DIP with through-hole mounting and lower thermal resistance (θJA = 67°C/W vs. FK's N/A). | Suitable for prototyping and legacy board upgrades where surface-mount LCCC rework is impractical. | Select 5962-9764201QEA only if manual soldering, board-level vibration tolerance, or socket compatibility is required. |
| SNJ54AHC157FK | Identical LCCC-20 package and electrical specs, but lacks QML-38535 certification documentation and lot traceability per MIL-I-45208. | Acceptable for non-mission-critical test equipment or ground support hardware with relaxed qualification requirements. | Choose SNJ54AHC157FK only when full QML documentation, radiation test reports, and certificate of conformance are not mandated. |
Compared with 5962-9764201Q2A, 5962-9764201QEA trades hermeticity for mechanical serviceability, while SNJ54AHC157FK reduces cost and documentation overhead at the expense of formal space/defense qualification - making the Q2A uniquely suited for flight-critical multiplexing where certified reliability is non-negotiable.

FAQ
What is the absolute maximum supply voltage rating for the 5962-9764201Q2A?
The 5962-9764201Q2A has an absolute maximum supply voltage (VCC) of –0.5 V to +7 V. However, functional operation is only guaranteed within the recommended range of 2 V to 5.5 V. Exceeding 5.5 V risks permanent damage even if duration is brief, and operation below 2 V may cause unpredictable output states or increased propagation delay in the 5962-9764201Q2A.
Does the 5962-9764201Q2A support 3.3-V-only operation with 5-V tolerant inputs?
No, the 5962-9764201Q2A does not feature 5-V tolerant inputs. Its input voltage range is limited to 0 V to VCC, meaning at VCC = 3.3 V, inputs must stay within 0–3.3 V. Applying 5 V to any input violates the absolute maximum rating and may damage the 5962-9764201Q2A. Level-shifting is required for mixed-voltage interfacing.
How is the strobe (G) pin used in timing-critical applications with the 5962-9764201Q2A?
In timing-critical applications, the G pin acts as a synchronous enable: when driven low, the selected A/B data appears at Y outputs after tPLH/tPHL (min 4.1 ns at 5 V); when driven high, all Y outputs go low within tPLZ/tPZH (max 12 ns). This allows precise gating of data bursts in the 5962-9764201Q2A without external latches.
Are the NC pins on the 5962-9764201Q2A required to be grounded or left floating?
The NC pins (17–20) on the 5962-9764201Q2A have no internal connection and must be left unconnected - neither grounded nor tied to VCC. Connecting them may induce parasitic coupling or violate LCCC thermal/mechanical design rules, potentially affecting long-term reliability of the 5962-9764201Q2A in hermetic packages.
What packaging and marking information confirms authenticity of the 5962-9764201Q2A?
Authentic 5962-9764201Q2A units use LCCC-20 (FK) packaging with laser-marked top-side text "5962-9764201Q2A" and "SNJ54AHC157FK". Traceability includes full lot code, date code, and QML certification mark per MIL-PRF-38535. Counterfeit units often omit the "SNJ" prefix or show inconsistent font spacing on the 5962-9764201Q2A marking.
