Product details
Overview
5962-8752501MCA from Texas Instruments is a military-grade dual D-type positive-edge-triggered flip-flop in a 14-pin CDIP (J) package, operating from 4.5 V to 5.5 V, with 10.5 ns max propagation delay at 5 V, TTL-compatible inputs, and guaranteed operation from −55°C to +125°C for aerospace and defense timing control applications.
For engineers reviewing the 5962-8752501MCA datasheet, 5962-8752501MCA pinout, 5962-8752501MCA application, or 5962-8752501MCA equivalent, key selection criteria include its radiation-hardened ceramic DIP packaging, dual independent preset/clear functionality, 125 MHz max clock frequency, and compatibility with legacy 5-V TTL logic systems requiring extended temperature reliability.
Technical Context
This device implements two independent edge-triggered D flip-flops with asynchronous active-low preset (PRE) and clear (CLR) inputs. Each flip-flop transfers data from D to Q on the positive-going edge of CLK when PRE and CLR are high, while low assertion of either PRE or CLR forces immediate output state override regardless of clock or data.
It uses ACT (Advanced CMOS TTL-compatible) logic technology, delivering rail-to-rail output swing, 24 mA drive capability, and input voltage tolerance up to 5.5 V - enabling direct interfacing with standard TTL outputs without level-shifting. The CDIP-J package provides hermetic ceramic sealing per MIL-STD-1835 GDIP1-T14.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - supports stable operation across full military-grade 5-V supply tolerance. |
| Max Propagation Delay | 10.5 ns at 5 V - enables reliable 125 MHz synchronous operation in high-speed control sequencers. |
| Operating Temperature | −55°C to +125°C - qualified for embedded avionics, missile guidance, and space-qualified subsystems. |
| Output Drive | ±24 mA - sufficient to directly drive multiple TTL loads or small capacitive buses without buffering. |
| Input Compatibility | TTL-voltage compatible - accepts standard TTL logic levels (VIH ≥ 2 V, VIL ≤ 0.8 V) without external biasing. |
| Package Type | Ceramic Dual In-Line Package (CDIP-J), 14-pin - hermetically sealed, MIL-STD-1835 compliant, lead-finish specified as "Call TI". |
| Max Clock Frequency | 125 MHz - verified under recommended operating conditions, supporting real-time digital state machine timing. |
Pinout & Package
Ceramic Dual In-Line Package (CDIP-J), 14-pin, 0.300-inch wide body, 5.08 mm maximum height, hermetically sealed with glass-frit lid per MIL-STD-1835 GDIP1-T14. Seating plane defined per JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1CLR | Active-low asynchronous clear for first flip-flop - forces Q = L, Q̅ = H independent of clock or data. |
| 2 | 1D | Data input for first flip-flop - sampled on rising edge of 1CLK when 1PRE and 1CLR are high. |
| 3 | 1CLK | Positive-edge-triggered clock for first flip-flop - transition from low to high latches 1D into 1Q. |
| 4 | 1PRE | Active-low asynchronous preset for first flip-flop - forces Q = H, Q̅ = L independent of clock or data. |
| 5 | 1Q | True output of first flip-flop - reflects latched 1D state after 1CLK↑, unless overridden by 1PRE/1CLR. |
| 6 | 1Q̅ | Inverted output of first flip-flop - complementary to 1Q, maintained during all valid states. |
| 7 | GND | Ground reference for both flip-flops - must be connected to system common return path. |
| 8 | VCC | Positive supply rail - requires 4.5–5.5 V with local decoupling near pin for noise immunity. |
| 9 | 2CLR | Active-low asynchronous clear for second flip-flop - forces Q = L, Q̅ = H independent of clock or data. |
| 10 | 2D | Data input for second flip-flop - sampled on rising edge of 2CLK when 2PRE and 2CLR are high. |
| 11 | 2CLK | Positive-edge-triggered clock for second flip-flop - transition from low to high latches 2D into 2Q. |
| 12 | 2PRE | Active-low asynchronous preset for second flip-flop - forces Q = H, Q̅ = L independent of clock or data. |
| 13 | 2Q | True output of second flip-flop - reflects latched 2D state after 2CLK↑, unless overridden by 2PRE/2CLR. |
| 14 | 2Q̅ | Inverted output of second flip-flop - complementary to 2Q, maintained during all valid states. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent D flip-flops | Two fully isolated storage elements sharing only VCC and GND - enables compact dual-channel synchronization or pipeline staging. |
| Asynchronous preset and clear | Separate PRE/CLR per flip-flop allows deterministic initialization or fault recovery without clock dependency. |
| TTL-compatible inputs | Accepts standard TTL logic thresholds (VIH ≥ 2 V, VIL ≤ 0.8 V) - eliminates need for level translators in mixed-logic systems. |
| Radiation-tolerant CDIP-J package | Hermetic ceramic construction meets MIL-PRF-38535 requirements for total ionizing dose (TID) and single-event effects (SEE) resilience. |
| High-speed AC performance | 125 MHz max clock frequency and 10.5 ns tPHL/tPLH support real-time digital control loops and test instrumentation timing. |

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 |
|---|---|---|---|
| SNJ54ACT74FK | LCCC-20 package (vs. CDIP-14); identical electrical specs and temp range (−55°C to +125°C); different pinout and board footprint. | Used where surface-mount assembly, higher I/O count, or improved thermal resistance (θJA = N/A) is required over through-hole CDIP. | Select SNJ54ACT74FK only if LCCC mounting and layout redesign are acceptable; not pin-compatible with 5962-8752501MCA. |
| 5962-8752501MDA | CFP-14 package (flatpack); same military qualification, temp range, and logic function; different mechanical form factor and lead finish ("Call TI"). | Preferred in applications requiring lower profile, conformal coating compatibility, or specific MIL-STD-883 test flow variants. | Choose 5962-8752501MDA when CFP mechanical constraints or alternate screening requirements govern; no PCB change compatibility. |
Compared with 5962-8752501MCA, SNJ54ACT74FK offers superior thermal performance in LCCC but demands full layout rework, while 5962-8752501MDA maintains identical logic behavior in a flatpack form - neither is pin-compatible, but both satisfy identical military timing, voltage, and environmental requirements.

FAQ
What is the absolute maximum supply voltage rating for the 5962-8752501MCA?
The 5962-8752501MCA has an absolute maximum supply voltage (VCC) rating of −0.5 V to +7 V. However, functional operation is only guaranteed within the recommended range of 4.5 V to 5.5 V. Exceeding 5.5 V may cause parametric degradation or latent reliability issues, even if no immediate failure occurs.
Does the 5962-8752501MCA support hot-swap or live-insertion?
No, the 5962-8752501MCA does not support hot-swap or live-insertion. Its CDIP-J package lacks bus-hold or Ioff protection circuitry, and applying VCC before GND or vice versa risks latch-up due to internal parasitic SCR structures. Power sequencing must follow GND-first, then VCC, with controlled ramp rates.
What is the meaning of "NC" pins in the 5962-8752501MCA pinout?
The 5962-8752501MCA has no NC (no-connect) pins. All 14 pins are electrically assigned: pins 1–6 and 9–14 serve dedicated logic functions (CLR, D, CLK, PRE, Q, Q̅), while pins 7 (GND) and 8 (VCC) provide power. This differs from some SOIC variants (e.g., SN74ACT74D) which include NC pins - the CDIP-J version uses every pin.
Can the 5962-8752501MCA operate reliably at 5.5 V with full 24 mA output drive?
Yes, the 5962-8752501MCA is fully characterized at 5.5 V for VOH ≥ 4.76 V and VOL ≤ 0.44 V under IOL = 24 mA and IOH = −24 mA conditions. These values meet TTL output compatibility requirements and are validated across the full −55°C to +125°C temperature range per the SCAS520H datasheet.
Is the 5962-8752501MCA RoHS-compliant?
The 5962-8752501MCA is not RoHS-compliant. As a military-spec CDIP-J device, it uses leaded solder and non-RoHS finishes per MIL-PRF-38535 Class V requirements. Its lead/ball finish is documented as "Call TI", and the package falls outside EU RoHS exemptions for high-reliability aerospace/defense applications.
