Product details
Overview
5962-9759201QCA from Texas Instruments is a dual positive-edge-triggered D-type flip-flop with independent preset and clear inputs, designed for synchronous logic control in military-grade digital systems. It operates across –55°C to 125°C, supports 5 V supply, delivers 100 MHz max clock frequency, and features 3.6 ns typical tPHL propagation delay. It is used in radiation-tolerant avionics timing circuits requiring deterministic state capture on clock rise.
For engineers reviewing the 5962-9759201QCA datasheet, 5962-9759201QCA pinout, 5962-9759201QCA application, or 5962-9759201QCA equivalent, key selection criteria include military temperature range compliance, CDIP-J package mechanical integrity, guaranteed setup/hold timing margins (tsu = 2 ns, th = 1 ns), and direct compatibility with TTL-level control signals in legacy flight computer subsystems.
Technical Context
This device implements two independent edge-triggered storage elements with asynchronous active-low preset and clear. Each flip-flop transfers D-input data to Q/Q outputs on the positive-going clock edge only when both PRE and CLR are high; otherwise, outputs are forced asynchronously. Clock triggering is voltage-threshold-based-not slew-rate dependent-ensuring robust operation under noisy power or slow-rising clocks.
The logic design enforces non-overlapping PRE/CLR priority: simultaneous low on both PRE and CLR yields undefined but non-latching output states (H†/H†), explicitly excluded from guaranteed VOH specification. Output drive capability is rated for 20 mA sink (IOL) and 1 mA source (IOH) under 4.5–5.5 V VCC, meeting standard TTL interface requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Dual D-type flip-flop with independent PRE/CLR, positive-edge clocking |
| Supply Voltage | 4.5 V to 5.5 V - compatible with legacy 5 V TTL bus systems |
| Operating Temperature | –55°C to 125°C - qualified per MIL-PRF-38535 for space and defense platforms |
| Max Clock Frequency | 100 MHz - enables high-speed state sequencing in real-time control loops |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1CLR | Asynchronous active-low clear for first flip-flop; forces Q1 = L, Q1̅ = H regardless of clock or D |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54F74J | Identical electrical specs, same CDIP-J package, identical marking and qualification per MIL-PRF-38535 | No functional difference; SNJ54F74J is alternate orderable designation for same device | Select 5962-9759201QCA when sourcing against DSCC drawing 5962-97592 |
| JM38510/34101BCA | Same function, CDIP-J package, –55°C to 125°C rating, but manufactured under different DSCC drawing (34101) | Approved for use in DoD programs requiring JM38510 lineage; identical pinout and timing | Choose JM38510/34101BCA only if BOM mandates specific DSCC source control drawing |
Compared with SNJ54F74J (identical form-fit-function twin) and JM38510/34101BCA (same package and spec but alternate DSCC lineage), 5962-9759201QCA offers direct traceability to DSCC specification 5962-97592 and is preferred for new designs requiring documented conformance to that exact drawing number.

FAQ
What is the maximum operating temperature range for the 5962-9759201QCA?
The 5962-9759201QCA is characterized for operation from –55°C to 125°C, fully compliant with MIL-PRF-38535 Class Q/V screening requirements. This range is verified across all electrical parameters including propagation delay, setup/hold times, and output drive strength - making it suitable for engine-mounted avionics and space payload electronics where ambient extremes are routine.
Does the 5962-9759201QCA support 3.3 V operation?
No, the 5962-9759201QCA is specified only for 4.5 V to 5.5 V VCC operation. Its input thresholds (VIH = 2 V, VIL = 0.8 V) and output drive (VOH ≥ 2.5 V at –1 mA) are optimized for 5 V TTL systems. Operating below 4.5 V violates recommended conditions and may result in undefined timing behavior or failure to meet setup/hold guarantees.
Is the 5962-9759201QCA pin-compatible with commercial SN74F74 variants?
Yes, the 5962-9759201QCA uses the same 14-pin CDIP-J footprint and pinout as SN74F74N and SN54F74J. However, it is not pin-compatible with SOIC-D or PDIP-N packages due to differing physical dimensions and lead spacing - board layout must match the 0.3-inch wide ceramic DIP outline.
What is the meaning of the "QCA" suffix in 5962-9759201QCA?
The "QCA" suffix denotes qualification per DSCC specification 5962-97592, with "QC" indicating compliance to the QML Class Q baseline and "A" specifying the revision level of the drawing. This suffix confirms full MIL-PRF-38535 Class Q testing, including burn-in, temperature cycling, and radiation hardness assurance protocols.
Can the 5962-9759201QCA be used in place of SN74F74D in a new design?
The 5962-9759201QCA is functionally identical to SN74F74D but differs in package (CDIP-J vs SOIC-D), temperature range (–55°C to 125°C vs 0°C to 70°C), and qualification level (military QML vs commercial). Substitution requires PCB redesign for through-hole mounting and validation of thermal/mechanical stress in extended environments - not a drop-in replacement.
