Product details
Overview
5962-9759001QSA from Texas Instruments is a military-grade octal D-type flip-flop with 3-state bus-driving outputs, edge-triggered on the positive clock transition, operating across −55°C to 125°C, and featuring buffered OE control for high-impedance output states-used in avionics data latching and MIL-STD-1553B interface registers.
For engineers reviewing the 5962-9759001QSA datasheet, 5962-9759001QSA pinout, 5962-9759001QSA application, or 5962-9759001QSA equivalent, key selection criteria include its CFP (W) package, 20-pin ceramic flatpack construction, guaranteed operation over full military temperature range, and compatibility with TTL-level bus buffering in radiation-tolerant systems.
Technical Context
This device implements eight independent edge-triggered D flip-flops synchronized to the rising edge of CLK, with asynchronous 3-state control via OE-enabling simultaneous data capture and bus isolation without affecting internal state retention. Its architecture supports parallel loading and bidirectional bus management in deterministic timing environments.
Designed for high-reliability military systems, it uses bipolar F-family logic with guaranteed propagation delays (tPLH/tPHL ≤ 8.5 ns at VCC = 5 V), robust noise immunity (VIH = 2 V min, VIL = 0.8 V max), and output drive capability up to 40 mA sink per channel under −55°C to 125°C conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | F-series TTL-ensures interoperability with legacy 5-V TTL systems and predictable timing margins. |
| Operating Temperature | −55°C to 125°C-qualified per MIL-PRF-38535 for use in airborne, spaceborne, and ground vehicle electronics. |
| Supply Voltage | 4.5 V to 5.5 V-stable operation within tight tolerance bands required for mission-critical power domains. |
| Max Clock Frequency | 100 MHz-supports high-speed data capture in real-time telemetry and command decoding circuits. |
| Output Drive | 40 mA sink per Q output-sufficient to directly drive terminated 50-Ω transmission lines or multiple TTL inputs without external buffers. |
| Propagation Delay | tPLH/tPHL ≤ 8.5 ns (VCC = 5 V, CL = 50 pF)-enables sub-10-ns setup/hold timing compliance in synchronous backplane interfaces. |
| 3-State Enable Delay | tPZH/tPLZ ≤ 12.5 ns-guarantees fast bus release for time-multiplexed shared-data-path architectures. |
Pinout & Package
Ceramic Flatpack (CFP) package, 20-pin, hermetically sealed, with 0.050″ lead pitch and JEDEC-standard pinout compatible with SN54F374 functional specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Data Inputs (D1–D8) | Asynchronous parallel data inputs sampled on CLK↑-enable simultaneous register loading from data buses. |
| 9 | GND | Signal reference plane for all logic and output stages-critical for noise rejection in mixed-signal avionics modules. |
| 10, 11, 13, 14, 15, 16, 17, 18 | Outputs (Q1–Q8) | True 3-state outputs capable of high-impedance disconnection-allows safe sharing of common data paths without bus contention. |
| 12 | VCC | Primary 5-V supply rail-must be decoupled locally to maintain switching noise margin below 0.3 Vpp. |
| 19 | CLK | Global clock input with Schmitt-triggered edge detection-ensures reliable sampling even with slow-rising or noisy system clocks. |
| 20 | OE | Active-low output enable-asserting low enables Q outputs; high places all Qs in high-Z-decouples register state from bus activity. |
Key Features
| Feature | Design Value |
|---|---|
| 8-bit parallel latch + 3-state bus driver | Single-package integration eliminates inter-chip skew and reduces PCB routing complexity in flight control I/O modules. |
| Rising-edge clock triggering | Enables precise synchronization with master timing generators in deterministic real-time systems such as radar pulse processing. |
| Buffered OE input | Prevents false output transitions during OE signal transitions-essential for glitch-free bus arbitration in MIL-STD-1553B remote terminal designs. |
| Military temperature qualification | Validated operation across −55°C to 125°C ensures reliability in uncontrolled environmental enclosures like UAV payload bays. |
| High-current sinking outputs | 40 mA per output supports direct connection to terminated RS-422 receivers or legacy TTL loads without level-shifting circuitry. |

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 |
|---|---|---|---|
| JM38510/34105BSA | Identical electrical specs, same CFP (W) package, identical marking format per MIL-PRF-38535 Class B. | No functional difference-direct second-source part qualified to same military standard. | Select when dual-sourcing or long-term obsolescence mitigation is required per DoD acquisition policy. |
| SNJ54F374W | Same die, identical pinout and timing, but marked per TI's legacy military nomenclature (non-5962 prefix). | Functionally interchangeable; used in earlier-generation platforms where documentation references SNJ54F374W. | Choose for legacy design refresh where bill-of-materials traceability to original TI military part numbers is mandated. |
Compared with 5962-9759001QSA, JM38510/34105BSA offers identical performance and qualification with enhanced supply chain resilience, while SNJ54F374W provides full functional equivalence with legacy documentation alignment-neither requires PCB redesign or timing revalidation.

FAQ
What is the absolute maximum supply voltage rating for the 5962-9759001QSA?
The absolute maximum supply voltage for the 5962-9759001QSA is −0.5 V to 7 V. Exceeding this range may cause permanent damage. For reliable operation, the recommended supply voltage is strictly 4.5 V to 5.5 V per MIL-PRF-38535 specifications. This rating applies to the 5962-9759001QSA across its full −55°C to 125°C operating range.
Does the 5962-9759001QSA support hot insertion or live bus connection?
The 5962-9759001QSA does not support hot insertion. Its absolute maximum ratings specify that voltages applied to outputs in the disabled or power-off state must remain within −0.5 V to 5.5 V. Applying bus signals before VCC stabilization risks violating these limits and damaging the 5962-9759001QSA. System-level hot-swap protection must be implemented externally.
What is the function of Pin 20 (OE) on the 5962-9759001QSA?
Pin 20 is the active-low Output Enable (OE) input. When OE is low, the eight Q outputs reflect the latched D-input states. When OE is high, all Q outputs enter a high-impedance state-disconnecting the device from the bus without affecting internal flip-flop states. This behavior is confirmed in the FUNCTION TABLE and applies identically across all operating temperatures for the 5962-9759001QSA.
Is the 5962-9759001QSA RoHS compliant?
The 5962-9759001QSA is not RoHS compliant. As a military-grade CFP (W) device manufactured to MIL-PRF-38535, it uses tin-lead solder finish and contains lead per EU RoHS exemption 7a. Its eco plan is listed as "TBD" with "Call TI" for lead/ball finish-consistent with legacy military components exempt from RoHS restrictions under applicable regulatory allowances.
How does the 5962-9759001QSA differ from commercial SN74F374 variants?
The 5962-9759001QSA differs from commercial SN74F374 variants in three critical ways: (1) it is screened and tested per MIL-PRF-38535 Class B for −55°C to 125°C operation, (2) it uses a hermetic ceramic flatpack (CFP/W) package instead of plastic SOIC or PDIP, and (3) it guarantees 40 mA output sink current across the full military temperature range-whereas SN74F374 specifies 48 mA only at 0°C to 70°C. These distinctions make the 5962-9759001QSA suitable for deployment where the SN74F374 is not qualified.
