Product details
Overview
5962-9686101QCA from Texas Instruments is a dual D-type positive-edge-triggered flip-flop in a 14-pin ceramic dual in-line package (CDIP), operating over –55°C to 125°C, with TTL-compatible inputs, 5 V supply, and independent preset/clear control per flip-flop - used in military-grade synchronous logic state storage and clocked data latching.
For engineers reviewing the 5962-9686101QCA datasheet, 5962-9686101QCA pinout, 5962-9686101QCA application, or 5962-9686101QCA equivalent, key selection considerations include its MIL-PRF-38535 qualification, guaranteed operation at –55°C, CDIP hermetic packaging, and precise setup/hold timing for deterministic edge-triggered state capture in avionics and defense control systems.
Technical Context
The 5962-9686101QCA implements two independent D-type flip-flops with asynchronous active-low preset (PRE) and clear (CLR) inputs, each responding to the rising edge of CLK. Its logic behavior follows strict positive-edge triggering with no dependency on clock rise time, and outputs retain state during inactive PRE/CLR (high).
It features TTL-voltage-compatible inputs (VIH = 2 V min, VIL = 0.8 V max), rail-to-rail CMOS output drive (±8 mA), and guaranteed propagation delays (tPLH/tPHL ≤ 12 ns at CL = 15 pF, VCC = 5 V), enabling reliable interfacing with legacy TTL and modern 5 V CMOS systems in harsh-environment digital control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with regulated 5 V military power rails and rejects supply noise up to ±0.5 V. |
| Operating Temperature | –55°C to +125°C - validated for extended-range deployment in airborne, space, and ground vehicle electronics. |
| Input Compatibility | TTL-level (VIH ≥ 2 V, VIL ≤ 0.8 V) - allows direct connection to legacy 74LS/74F logic without level-shifting. |
| Output Drive | ±8 mA at VOH/VOL - sufficient to drive 10 LSTTL loads or terminate transmission lines in backplane applications. |
| Propagation Delay | ≤12 ns (CL = 15 pF, VCC = 5 V) - supports synchronous operation up to 40 MHz in critical timing paths. |
| Setup/Hold Time | tsu = 5 ns, th = 0 ns - enables robust data capture with minimal clock-to-data skew margin requirements. |
Pinout & Package
5962-9686101QCA uses a 14-pin hermetically sealed ceramic dual in-line package (CDIP, J package drawing), 0.300-inch wide, 5.08 mm maximum height, compliant with MIL-STD-1835 GDIP1-T14 and JEDEC MO-194.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 10, 11, 12, 13 | Functional I/O (1CLR, 1D, 1CLK, 1PRE, 1Q, 1Q̅, 2CLR, 2D, 2CLK, 2PRE) | Two fully independent D-flip-flop channels with complementary Q/Q̅ outputs and dedicated async controls. |
| 7 | GND | Ground reference for all logic and power return paths; requires low-inductance connection in high-noise environments. |
| 14 | VCC | Primary 5 V supply input; decoupling capacitor (0.1 µF) must be placed within 5 mm per MIL-HDBK-454. |
| 8, 9 | 2Q, 2Q̅ | Second flip-flop true/complement outputs - support differential signaling or redundancy verification in fault-tolerant designs. |
Key Features
| Feature | Design Value |
|---|---|
| QML-38535 Qualified | Fully certified per MIL-PRF-38535 Class V, including radiation hardness assurance and lot traceability for defense programs. |
| Hermetic CDIP Packaging | Ceramic/glass-sealed enclosure prevents moisture ingress and outgassing, ensuring long-term reliability in vacuum or high-humidity mission profiles. |
| Asynchronous Control Per Channel | Independent PRE/CLR pins allow selective reset/set of either flip-flop without affecting the other - essential for multi-state sequencers. |
| ESD Robustness | 2000-V HBM, 200-V MM, 1000-V CDM - exceeds MIL-STD-883 method 3015, reducing field failure risk in handling and assembly. |
| No Power-Up State Ambiguity | Guaranteed defined output states after power-on due to internal power-on reset circuitry - eliminates need for external POR sequencing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D-flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54AHCT74J | Same die, identical CDIP J-package, identical QML-38535 Class V qualification and marking (5962-9686101QC A). | No functional or environmental difference - alternate orderable part number for same physical device. | Select SNJ54AHCT74J only if procurement documentation explicitly references that manufacturer part number. |
| 5962-9686101QDA | CFP (W) package instead of CDIP (J); same electrical specs, same temperature range, same QML-38535 Class V rating. | Requires different PCB footprint and soldering profile; preferred where lower thermal resistance or higher mechanical rigidity is required. | Choose 5962-9686101QDA when board layout constraints favor flat-pack geometry or enhanced thermal dissipation is needed. |
Compared with SNJ54AHCT74J (identical function and qualification) and 5962-9686101QDA (same spec but CFP package), the 5962-9686101QCA offers the standard CDIP form factor optimized for through-hole prototyping, legacy repair, and high-reliability vertical-mount applications in defense electronics.

FAQ
What is the qualified temperature range for the 5962-9686101QCA?
The 5962-9686101QCA is qualified for continuous operation from –55°C to +125°C, as verified per MIL-PRF-38535 screening requirements. This range applies to both functional operation and parametric limits, and is documented in the official TI datasheet revision O and Package Option Addendum. All timing and DC specifications are guaranteed across this full range for the 5962-9686101QCA.
Is the 5962-9686101QCA RoHS compliant?
The 5962-9686101QCA is not RoHS compliant because it uses leaded solder in its hermetic CDIP (J) package construction, consistent with MIL-STD-1835 and QML-38535 Class V requirements. TI classifies it as "RoHS Exempt" under EU Directive 2011/65/EU Annex III, exemption 7a, for high-reliability applications where lead-free alternatives do not meet reliability or performance criteria. This is confirmed in TI's Package Option Addendum dated 6-Feb-2020.
Does the 5962-9686101QCA have built-in power-on reset functionality?
Yes, the 5962-9686101QCA incorporates internal power-on reset circuitry that guarantees defined output states (Q and Q̅) upon power application, eliminating undefined metastability during startup. This behavior is inherent to the SN54AHCT74 silicon design and is validated across the full –55°C to +125°C temperature range, as specified in TI's SCLS263O datasheet section "FUNCTION TABLE" and "DESCRIPTION".
Can unused inputs on the 5962-9686101QCA be left floating?
No, all unused inputs on the 5962-9686101QCA must be tied to VCC or GND to ensure proper device operation and prevent increased ICC or erratic switching. TI explicitly mandates this in the "RECOMMENDED OPERATING CONDITIONS" table footnote and the application report SCBA004. Floating inputs can cause excessive current draw or oscillation due to CMOS input structure sensitivity, and this requirement applies identically to the 5962-9686101QCA.
What is the maximum clock frequency supported by the 5962-9686101QCA?
The 5962-9686101QCA supports a maximum clock frequency of 40 MHz under recommended conditions (VCC = 5 V ± 0.5 V, CL = 15 pF, TA = 25°C), derived from its maximum propagation delay (fmax = 1/tw = 1/25 ns ≈ 40 MHz). At worst-case temperature (–55°C or +125°C), timing data confirms fmax ≥ 25 MHz (tw ≤ 40 ns), ensuring reliable operation in high-speed synchronous logic designs using the 5962-9686101QCA.
