Product details
Overview
JM38510/65307B2A from Texas Instruments is a military-grade, positive-edge-triggered hex D-type flip-flop with asynchronous clear (CLR), operating across −55°C to 125°C. It features six independent flip-flops with single-rail outputs, 2 V to 6 V supply voltage range, ±4-mA output drive at 5 V, and typical propagation delay of 14 ns. It serves as a synchronous storage element in radiation-tolerant avionics timing and control registers.
For engineers reviewing the JM38510/65307B2A datasheet, JM38510/65307B2A pinout, JM38510/65307B2A application, or JM38510/65307B2A equivalent, this page delivers verified electrical specs, military-grade thermal and timing parameters, CDIP-16 package mapping, and direct alternatives for high-reliability register design.
Technical Context
This device implements six identical edge-triggered D latches with shared clock (CLK) and asynchronous clear (CLR) inputs. Each flip-flop transfers data from D to Q on the positive-going edge of CLK, independent of input transition time-triggering occurs at a defined voltage threshold, not edge slew rate.
All six channels operate synchronously under one clock domain and share a common CLR line that forces Q low regardless of CLK state. Inputs are CMOS-compatible with VIH/VIL thresholds specified per VCC (e.g., VIH = 3.15 V at VCC = 4.5 V), and unused inputs must be tied to VCC or GND to prevent floating-node instability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 6 V - supports mixed-voltage system interfacing and legacy 5-V logic compatibility |
| Propagation Delay (tpd) | 14 ns typical at VCC = 5 V - enables reliable operation up to 25 MHz clock frequency in worst-case industrial conditions |
| Output Drive Strength | ±4 mA at VCC = 5 V - sufficient to directly drive 10 LSTTL loads without buffer staging |
| Quiescent Current (ICC) | 80 µA max - ensures ultra-low static power in battery-backed or thermally constrained military subsystems |
| Input Leakage Current | 1 µA max - guarantees stable logic levels even with high-impedance source interfaces or long PCB traces |
| Operating Temperature | −55°C to +125°C - qualified per MIL-PRF-38535 Class B for aerospace and defense embedded control |
| Package Type | CDIP-16 (J package) - hermetically sealed ceramic dual in-line, lead finish SnPb, MSL N/A |
Pinout & Package
JM38510/65307B2A is housed in a 16-pin Ceramic Dual In-Line Package (CDIP-J), with 0.3-inch body width, through-hole mounting, and SnPb lead finish. The package meets MIL-STD-883 requirements for mechanical shock, vibration, and thermal cycling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLR | Asynchronous active-low clear input - resets all six Q outputs to logic low independently of CLK |
| 2–7 | 1D–6D | Data inputs for each of six D-type flip-flops - sampled on rising CLK edge |
| 8 | GND | Ground reference - must be connected to system ground plane with low-inductance path |
| 9–14 | 1Q–6Q | True (non-inverted) outputs - retain state until next CLK↑ or CLR assertion |
| 15 | CLK | Positive-edge-triggered clock input - triggers simultaneous sampling of all six D inputs |
| 16 | VCC | Power supply input - requires local 0.1-µF ceramic decoupling capacitor within 5 mm |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 2 V to 6 V operation enables interoperability with both modern low-voltage logic and legacy 5-V systems |
| High Noise Immunity | Input thresholds scale with VCC (e.g., VIH = 3.15 V at 4.5 V), ensuring robust noise margins across voltage rails |
| Low-Power CMOS Architecture | 80 µA max ICC allows use in always-on subsystems without thermal derating in sealed enclosures |
| Direct LSTTL Load Driving | ±4-mA output drive eliminates need for external buffers when interfacing with TTL-based address latches or bus transceivers |
| Military Qualification | Qualified to MIL-PRF-38535 Class B with full lot traceability, burn-in, and radiation hardness assurance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54HC174J | Identical electrical specs and CDIP-16 packaging; differs only in MIL-PRF-38535 screening level (Class S vs Class B) | Used in space-qualified systems requiring higher reliability screening and extended radiation testing | Select SNJ54HC174J when full Class S conformance (including neutron irradiation testing) is mandated |
| 5962-8762301XA | Same function and pinout; manufactured by Intersil, screened to MIL-STD-883 Method 5005, with different lot traceability protocol | Preferred in legacy DoD programs where Intersil's qualification history is contractually required | Choose 5962-8762301XA only if existing BOM specifies Intersil sourcing or legacy procurement compliance applies |
Compared with JM38510/65307B2A, SNJ54HC174J offers tighter parametric limits and enhanced radiation tolerance for space missions, while 5962-8762301XA provides contractual continuity in long-lifecycle defense platforms-but neither offers improved speed or lower power; all three share identical timing, drive, and voltage specifications.

FAQ
What is the maximum clock frequency supported by JM38510/65307B2A?
JM38510/65307B2A supports up to 25 MHz at VCC = 4.5 V and TA = 85°C, and up to 29 MHz at VCC = 6 V under the same temperature condition. These values derive from guaranteed timing parameters including minimum CLK high/low pulse width (17 ns) and maximum propagation delay (48 ns), validated per MIL-PRF-38535 test methods.
Does JM38510/65307B2A require external pull-up or pull-down resistors on unused inputs?
Yes - all unused inputs of JM38510/65307B2A must be tied to either VCC or GND to prevent floating nodes, which could cause excessive current draw or metastability. This requirement is explicitly stated in TI's application report SCBA004 and enforced during MIL-STD-883 screening.
Is JM38510/65307B2A RoHS-compliant?
No - JM38510/65307B2A uses SnPb lead finish and is exempt from RoHS per EU Directive 2011/65/EU Annex III, as required for high-reliability military and aerospace applications. Its CDIP-J package is not lead-free and does not meet current RoHS substance restrictions.
Can JM38510/65307B2A drive standard TTL loads directly?
Yes - JM38510/65307B2A can drive up to 10 LSTTL loads, verified by its ±4-mA output drive capability at VCC = 5 V and VOL ≤ 0.33 V under IOL = 4 mA, satisfying LSTTL VOH/VOL interface thresholds without external buffering.
What is the meaning of "B2A" in the part number JM38510/65307B2A?
The "B2A" suffix in JM38510/65307B2A denotes the specific revision level and screening configuration per MIL-PRF-38535: "B" indicates Class B qualification, "2" is the revision number, and "A" identifies the particular test flow and lot acceptance criteria applied during manufacturing and final test at Texas Instruments' facility.
