Product details
Overview
5962-9314801QRA from Texas Instruments is a military-grade octal positive-edge-triggered D-type flip-flop with clock enable, operating across –55°C to 125°C. It features 8-bit synchronous storage, high-drive outputs (–32 mA IOH, 64 mA IOL), <1 V output ground bounce at 5 V, and latch-up immunity >500 mA per JESD-17 - deployed in avionics timing registers and radiation-tolerant control logic.
For engineers reviewing the 5962-9314801QRA datasheet, 5962-9314801QRA pinout, 5962-9314801QRA application, or 5962-9314801QRA equivalent, this page delivers verified electrical specs, military-qualified thermal and ESD performance, JEDEC-standard CDIP-20 package details, and direct alternatives for legacy system sustainment and MIL-PRF-38535 compliance.
Technical Context
The 5962-9314801QRA implements eight independent D-type latches synchronized to the rising edge of CLK only when CLKEN is low, preventing false triggering via CLKEN transitions. Its EPIC-IIB BiCMOS architecture enables TTL-compatible input thresholds (VIH = 2 V, VIL = 0.8 V) while delivering rail-to-rail CMOS-level outputs under load.
Timing is characterized over full military temperature range: tsu = 2.5 ns (data), th = 1.8 ns (data), tPLH/tPHL = 4.5/5.3 ns typical at 5 V, supporting up to 150 MHz clock frequency with CL = 50 pF. Absolute maximum ratings include VCC = –0.5 V to 7 V and storage at –65°C to 150°C.

Pinout & Package
Ceramic Dual-In-Line Package (CDIP), 20-pin, hermetically sealed, compliant with MIL-STD-883 and MIL-PRF-38535 Class Q/V. Pin 1 marked by notch or dot; body material is ceramic with Kovar leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLKEN | Active-low clock enable - disables clock propagation when high, preventing spurious state changes |
| 2–9, 11–18 | 1D–8D, 1Q–8Q | Data inputs and true outputs for eight independent D-flip-flops - no complemented outputs provided |
| 10 | GND | Digital ground reference - must be low-impedance connection to minimize ground bounce (VOLP < 1 V) |
| 20 | VCC | Positive supply - decoupling capacitor required within 1 cm to suppress switching noise |
| 19 | CLK | Buffered clock input - edge-triggered on rising transition; immune to slow input edges due to Schmitt-trigger input stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-9314801Q2A | LCCC-20 ceramic package (FK), same electrical specs and military temp range | Higher thermal conductivity and lower inductance than CDIP; preferred for high-frequency PCB layouts | Select when board layout requires superior RF immunity or tighter thermal management |
| SNJ54ABT377J | Same CDIP-20 package and military spec, but non-qualified per MIL-PRF-38535 Class Q/V | Lacks lot traceability, screening, and burn-in required for Class Q spaceflight or nuclear safety-critical use | Acceptable for non-safety-critical defense subsystems where full Class Q documentation is not mandated |
Compared with 5962-9314801QRA, the 5962-9314801Q2A offers improved high-frequency stability in LCCC packaging, while SNJ54ABT377J provides identical functionality at lower cost and documentation rigor - enabling tiered sourcing for development, qualification, and production phases.

FAQ
What is the maximum clock frequency supported by the 5962-9314801QRA?
The 5962-9314801QRA supports a maximum clock frequency of 150 MHz under recommended operating conditions (VCC = 5 V, TA = 25°C, CL = 50 pF). This value is confirmed in the switching characteristics table of the SCBS156E datasheet and applies across its full military temperature range with appropriate derating.
Does the 5962-9314801QRA have complementary Q̅ outputs?
No, the 5962-9314801QRA provides only true Q outputs (pins 2–9 and 11–18); it does not include inverted Q̅ outputs. The device is an octal D-type flip-flop with clock enable, and all eight channels deliver non-inverted registered data.
Is the 5962-9314801QRA RoHS-compliant?
The 5962-9314801QRA uses a ceramic DIP (J) package with lead finish specified as "Call TI" in TI's packaging addendum; it is not RoHS-compliant by default. It conforms to MIL-PRF-38535 Class Q requirements, which permit Pb-based finishes for high-reliability applications where lead-free alternatives are not qualified.
What is the purpose of the CLKEN pin on the 5962-9314801QRA?
The CLKEN pin (Pin 1) is an active-low clock enable that gates the CLK signal. When CLKEN is high, the clock is blocked and Q outputs retain their previous state regardless of CLK transitions. This allows precise control over register updates without requiring external gating logic, reducing timing uncertainty in synchronous systems.
Can the 5962-9314801QRA operate at 3.3 V supply voltage?
No, the 5962-9314801QRA is specified only for 4.5 V to 5.5 V supply operation per its recommended operating conditions. Attempting 3.3 V operation violates the minimum VCC requirement and will result in undefined logic states, increased propagation delay, and potential functional failure - it is not compatible with 3.3 V logic families.
