Product details
Overview
5962-8752501MDA from Texas Instruments is a dual D-type positive-edge-triggered flip-flop in a 14-pin CFP (ceramic flatpack) package, operating from 4.5 V to 5.5 V, with 10.5 ns max propagation delay at 5 V, TTL-voltage-compatible inputs, and guaranteed operation from −55°C to +125°C for military-grade systems including radar timing and avionics control logic.
For engineers reviewing the 5962-8752501MDA datasheet, 5962-8752501MDA pinout, 5962-8752501MDA application, or 5962-8752501MDA equivalent, this device serves as a radiation-tolerant, high-reliability storage element in synchronous digital subsystems requiring deterministic edge-triggered state retention under extended temperature and voltage stress.
Technical Context
The 5962-8752501MDA implements two independent D-type flip-flops with asynchronous preset (PRE) and clear (CLR) inputs active-low, enabling immediate output forcing regardless of clock state. Each flip-flop transfers data from D to Q on the positive-going edge of CLK, with setup time of 0 ns (min) and hold time of 1 ns (min) at 5 V.
It uses ACT (Advanced CMOS TTL-compatible) logic technology, delivering 24 mA output drive capability (IOH/IOL), input voltage tolerance up to 5.5 V, and absolute maximum ratings including VCC = −0.5 V to 7 V and storage temperature from −65°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - supports stable operation across MIL-STD-704 aircraft power bus transients |
| Max tpd | 10.5 ns at 5 V - enables ≤125 MHz clock frequency in synchronous logic chains |
| Output Drive | ±24 mA - drives standard TTL loads directly without buffer stages |
| Input Compatibility | TTL-voltage compatible - interfaces directly with legacy 74LS/74F logic without level shifters |
| Operating Temp | −55°C to +125°C - qualified per MIL-PRF-38535 for harsh-environment deployment |
| Propagation Skew | ≤2 ns between Q and Q̅ outputs - ensures clean complementary signal pairs for differential clocking |
| Power Dissipation | 45 pF Cpd at 1 MHz - predicts low dynamic power in high-frequency toggle applications |
Pinout & Package
5962-8752501MDA is housed in a 14-lead ceramic flatpack (CFP-W) package with gull-wing leads, hermetically sealed per MIL-STD-1835 GDIP1-T14, 5.08 mm max height, and lead finish specified as "Call TI" per TI's packaging addendum.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 CLR | Asynchronous Clear (1st FF) | Active-low reset forces Q₁ = L, Q̅₁ = H independently of clock |
| 2 D | Data Input (2nd FF) | Sampled on rising CLK edge when PRE₂ and CLR₂ are high |
| 3 CLK | Clock Input (1st FF) | Positive-edge-triggered; voltage-level sensitive, not slew-rate dependent |
| 4 PRE | Asynchronous Preset (1st FF) | Active-low set forces Q₁ = H, Q̅₁ = L independently of clock |
| 5 Q | True Output (1st FF) | Complementary to Q̅; latched value after CLK↑ with valid setup/hold |
| 6 Q̅ | Inverted Output (1st FF) | Guaranteed complementary to Q; usable as feedback or enable signal |
| 7 GND | Ground Reference | Primary return path for all I/O and internal logic; must be low-impedance |
| 8 VCC | Supply Voltage | +5 V nominal supply; decoupling required within 10 mm per JEDEC guidelines |
| 9 CLR | Asynchronous Clear (2nd FF) | Independent reset for second flip-flop; no crosstalk with first FF |
| 10 D | Data Input (2nd FF) | Isolated from D₁; allows independent data loading per channel |
| 11 CLK | Clock Input (2nd FF) | Shared clock domain possible; no internal synchronization between FFs |
| 12 PRE | Asynchronous Preset (2nd FF) | Independent preset; enables dual-channel initialization without gating |
| 13 Q | True Output (2nd FF) | Functionally identical to Q₁; supports parallel register or pipeline staging |
| 14 Q̅ | Inverted Output (2nd FF) | Provides native complement for differential signaling or XOR logic |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| SNJ54ACT74J | Same ACT core, CDIP-14 package; higher θJA (80°C/W vs. CFP's ~100°C/W), non-hermetic ceramic body | Limited to lower-power or less thermally constrained military boards; lacks CFP's hermetic reliability | Prefer 5962-8752501MDA for sealed environments or high-vibration applications |
| SNJ54ACT74FK | LCCC-20 package; includes 6 NC pins and different pinout; same electrical specs but larger footprint | Used where board area is less constrained and lead count flexibility supports mixed-signal integration | Choose 5962-8752501MDA for drop-in replacement in existing CFP footprints and thermal profiles |
Compared with SNJ54ACT74J and SNJ54ACT74FK, the 5962-8752501MDA offers superior hermetic sealing, tighter thermal resistance control in CFP form factor, and direct compatibility with legacy CFP-based guidance and comms hardware layouts.

FAQ
What is the maximum clock frequency supported by the 5962-8752501MDA?
The 5962-8752501MDA supports a maximum clock frequency of 125 MHz over its full operating temperature range (−55°C to +125°C), with typical operation up to 145 MHz at 25°C. This is derived from its 10.5 ns max propagation delay and verified timing characteristics in the SCAS520H datasheet. The 5962-8752501MDA maintains this performance without derating under military-grade thermal and voltage stress conditions.
Does the 5962-8752501MDA require external pull-up or pull-down resistors on unused inputs?
Yes - all unused inputs of the 5962-8752501MDA must be held at VCC or GND to ensure proper device operation and prevent floating-node-induced current leakage or metastability. This requirement is explicitly stated in Note 3 of the SCAS520H datasheet and applies equally to PRE, CLR, D, and CLK inputs not in use. The 5962-8752501MDA does not include internal termination.
Is the 5962-8752501MDA RoHS compliant?
The 5962-8752501MDA is not RoHS compliant in its standard configuration; it is a legacy military-grade part with leaded solder finish and packaging specified as "Call TI" for lead/ball finish per TI's Package Option Addendum. Its CFP-W package falls under MIL-PRF-38535 Class V, which permits Pb-containing finishes for reliability-critical applications where RoHS exemptions apply.
Can the 5962-8752501MDA drive standard TTL loads directly?
Yes - the 5962-8752501MDA provides ±24 mA output drive (IOH/IOL) at VCC = 5.5 V, meeting or exceeding standard TTL fan-out requirements (10x 74LS loads). Its TTL-voltage-compatible inputs and rail-to-rail output swing allow direct interface with 74LS, 74F, and other bipolar logic families without level-shifting circuitry. This capability is confirmed in the recommended operating conditions and electrical characteristics tables of the 5962-8752501MDA datasheet.
What is the meaning of "MDA" in the 5962-8752501MDA part number?
The "MDA" suffix in 5962-8752501MDA denotes the specific package variant within the 5962-8752501 military specification: "M" indicates microcircuit, "D" identifies the CFP (ceramic flatpack) package type, and "A" specifies the revision level per MIL-PRF-38535. This suffix distinguishes it from other variants like 5962-8752501MCA (CDIP) and 5962-8752501M2A (LCCC), all sharing the same ACT74 logic function but differing in mechanical form and screening.
