Product details
Overview
84088012A from Texas Instruments is a dual J-K negative-edge-triggered flip-flop IC designed for synchronous logic control in military-grade digital systems. It operates across −55°C to 125°C, supports 2 V to 6 V supply voltage, delivers ±4-mA output drive at 5 V, exhibits typical propagation delay of 13 ns, and draws ≤40 µA ICC - enabling reliable state storage and toggle operation in high-reliability timing and control circuits.
For engineers reviewing the 84088012A datasheet, 84088012A pinout, 84088012A application, or 84088012A equivalent, this page provides verified functional identity, LCCC-FK package mapping, confirmed J-K flip-flop behavior with independent preset/clear, and validated alternatives for radiation-tolerant or extended-temperature logic design.
Technical Context
The 84088012A implements two fully independent J-K flip-flops, each with asynchronous active-low PRE and CLR inputs that override clocked operation. Data at J and K inputs is latched on the negative-going edge of CLK, with setup time as low as 17 ns (at VCC = 6 V) and zero hold time requirement.
Its logic diagram confirms internal transmission-gate-based edge-triggering architecture with no dependency on CLK fall time; triggering occurs at a defined voltage threshold. The device supports toggle mode when J and K are tied high, and guarantees stable outputs under worst-case timing margins per MIL-PRF-38535 Class B requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Dual J-K negative-edge-triggered flip-flop with independent preset and clear |
| Supply Voltage Range | 2 V to 6 V - enables interoperability with 3.3 V and 5 V logic families |
| Propagation Delay (tpd) | 13 ns typical at VCC = 5 V - supports ≥20 MHz clock frequency in system-level timing paths |
| Output Drive | ±4 mA at 5 V - sufficient to directly drive 10 LSTTL loads without buffering |

Pinout & Package
84088012A is housed in a 20-terminal ceramic leadless chip carrier (LCCC-FK) package with hermetic sealing and gold-plated terminations for high-reliability applications. Pin numbering follows JEDEC standard FK outline with Pin 1 located at top-left corner (Q1 quadrant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 2CLR | Active-low asynchronous clear for second flip-flop - forces Q2 = 0, Q2̅ = 1 regardless of clock or data |
| 2 | 2CLK | Clock input for second flip-flop - negative-edge-triggered latch point for J2/K2 data |
| 3 | NC | No internal connection - must be left unconnected or tied to GND/VCC per layout guidelines |
| 4 | 2K | Data input for second flip-flop - determines next-state logic with J2 and clock edge |
| 5 | 2J | Data input for second flip-flop - used with K2 to define set, reset, hold, or toggle behavior |
| 6 | 1J | Data input for first flip-flop - defines transition logic in conjunction with 1K and 1CLK |
| 7 | 1PRE | Active-low asynchronous preset for first flip-flop - forces Q1 = 1, Q1̅ = 0 independently of clock |
| 8 | NC | No internal connection - electrically isolated; no routing required |
| 9 | 1Q | True output of first flip-flop - reflects stored state after valid clock edge and setup compliance |
| 10 | 1Q̅ | Complementary output of first flip-flop - provides inverted logic for differential signaling or feedback |
| 11 | 1K | Data input for first flip-flop - completes J-K truth table functionality with 1J and 1CLK |
| 12 | 1CLK | Clock input for first flip-flop - negative-edge sampling point synchronized to system timing reference |
| 13 | NC | No internal connection - unused terminal; no electrical or thermal function |
| 14 | 2Q | True output of second flip-flop - provides parallel state storage for dual-channel control logic |
| 15 | VCC | Positive supply rail - must be decoupled locally with 0.1 µF ceramic capacitor near Pin 15 |
| 16 | 1CLR | Active-low asynchronous clear for first flip-flop - resets Q1 to 0, Q1̅ to 1 unconditionally |
| 17 | 2Q̅ | Complementary output of second flip-flop - enables direct use in XOR, enable, or reset feedback paths |
| 18 | GND | Ground reference - requires low-inductance return path to minimize switching noise coupling |
| 19 | NC | No internal connection - thermally and electrically isolated; no PCB trace needed |
| 20 | 2PRE | Active-low asynchronous preset for second flip-flop - sets Q2 = 1, Q2̅ = 0 independent of clock |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (2–6 V) | Supports mixed-voltage system integration without level-shifting circuitry |
| Negative-edge clock triggering | Eliminates sensitivity to CLK fall time; enables precise timing alignment in synchronous designs |
| Asynchronous preset/clear per flip-flop | Enables independent initialization or forced reset without disrupting other channel operation |
| Low input current (≤1 µA) | Minimizes loading on upstream drivers and preserves signal integrity in fan-out-critical paths |
| Toggle mode via J=K=HIGH | Provides divide-by-two functionality using single device - reduces component count in clock division |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual J-K flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54HC112J | Same logic function and military temperature range (−55°C to 125°C), but in 16-pin CDIP package with through-hole mounting and different pinout (no NC pins, shared VCC/GND) | Preferred for legacy board rework or hand-soldered prototyping where LCCC reflow is unavailable | Select SNJ54HC112J only if mechanical compatibility with existing CDIP footprints is required; not pin-compatible with 84088012A |
| SNJ54HC112W | Identical logic and temperature rating, packaged in 16-pin CFP (ceramic flatpack) with gull-wing leads and different thermal profile (θJA = 65°C/W vs. LCCC's 50°C/W) | Better suited for conduction-cooled modules where CFP's lower profile and leaded interface simplify thermal interface design | Choose SNJ54HC112W when board-level thermal management relies on conductive cooling rather than convective airflow around LCCC body |
Compared with SNJ54HC112J and SNJ54HC112W, 84088012A offers superior high-frequency stability due to LCCC's lower parasitic inductance, tighter timing margin control via dedicated NC pins for grounding, and enhanced EMI resilience from hermetic ceramic construction - critical for RF-adjacent digital control in defense electronics.

FAQ
What is the exact package type and pin count for 84088012A?
84088012A uses a 20-terminal ceramic leadless chip carrier (LCCC-FK) package as confirmed by TI's Package Option Addendum and datasheet Figure 1. It features 20 metallized terminations arranged in a square grid with Pin 1 at the top-left corner (Q1 quadrant), including four NC pins and dedicated VCC/GND placements optimized for high-reliability layout.
Does 84088012A support true dual independent operation of both J-K flip-flops?
Yes, 84088012A provides two fully independent J-K flip-flops, each with dedicated PRE, CLR, CLK, J, K, Q, and Q̅ signals. The datasheet Function Table and logic diagram confirm separate asynchronous control and edge-triggered data capture - no shared internal nodes or timing dependencies exist between Channel 1 and Channel 2.
What is the maximum guaranteed clock frequency for 84088012A at 5 V supply?
At VCC = 5 V, 84088012A guarantees a minimum clock frequency of 20 MHz across the full −55°C to +125°C operating range, based on timing parameter tw(CLK high/low) ≤ 25 ns and fclock min values in the Recommended Operating Conditions table of SCLS099F.
Is 84088012A compatible with standard 74HC logic voltage levels?
Yes, 84088012A maintains full 74HC-compatible input thresholds (VIH = 3.15 V, VIL = 1.35 V at VCC = 4.5 V) and output drive capability (VOH ≥ 3.98 V, VOL ≤ 0.26 V at IO = ±4 mA), ensuring interoperability with commercial 74HC-series devices in mixed-sourcing designs.
How does the LCCC package of 84088012A impact thermal performance compared to plastic SOIC versions?
The LCCC-FK package of 84088012A achieves significantly lower thermal resistance than plastic SOIC variants - with θJA ≈ 50°C/W (estimated from TI's LCCC thermal models) versus 73°C/W for D-package SOIC. This enables higher sustained power density and improved reliability in convection-limited military enclosures.
