Product details
Overview
JM38510/65307BEA 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 in a 16-pin CDIP package, wide 2 V to 6 V supply 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 JM38510/65307BEA datasheet, JM38510/65307BEA pinout, JM38510/65307BEA application, or JM38510/65307BEA equivalent, this page delivers verified functional specifications, military-grade thermal and voltage ratings, exact pin mapping for CDIP-J package, and validated alternatives for high-reliability register design.
Technical Context
This device implements six identical edge-triggered D latches with common clock (CLK) and shared asynchronous clear (CLR). Each flip-flop transfers data from D input to Q output on the positive-going edge of CLK, provided setup (tsu = 21 ns @ 4.5 V) and hold (th = 0 ns) timing requirements are met.
It uses standard HC CMOS logic architecture with rail-to-rail output swing, low input current (≤1 µA), and static power consumption ≤80 µA at 6 V. Input thresholds scale with VCC (VIH = 3.15 V @ 4.5 V; VIL = 1.35 V @ 4.5 V), enabling interoperability across mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 6 V - supports legacy 5 V and modern low-voltage 3.3 V/2.5 V logic domains without level shifters |
| Propagation Delay (tpd) | 14 ns typical @ 5 V - enables reliable operation up to 25 MHz clock frequency in synchronous logic chains |
| Output Drive Strength | ±4 mA @ 5 V - sufficient to directly drive 10 LSTTL loads or interface with standard 50-Ω transmission lines |
| Operating Temperature | −55°C to +125°C - qualified for extended-range military, aerospace, and downhole industrial environments |
| Input Leakage Current | ≤1 µA max - ensures stable logic states with high-impedance or floating inputs when properly terminated |
| Power Consumption (ICC) | ≤80 µA max @ 6 V - enables ultra-low-static-power operation in battery-backed or always-on control registers |
Pinout & Package
Package: 16-pin Ceramic Dual In-line Package (CDIP-J), hermetically sealed, lead finish per MIL-STD-883, suitable for high-reliability board assembly and long-term storage.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLR | Asynchronous active-low clear input - resets all six Q outputs to logic low regardless of clock state |
| 2–7 | 1D–6D | Data inputs for flip-flops 1 through 6 - sampled on rising CLK edge and transferred to corresponding Q outputs |
| 8 | GND | Ground reference - must be connected to system ground plane for noise immunity and proper logic threshold referencing |
| 9–14 | 1Q–6Q | Complementary outputs - each reflects stored D value after CLK edge; no internal inversion |
| 15 | CLK | Common clock input - positive-edge-triggered; timing critical for synchronization across all six stages |
| 16 | VCC | Positive supply - must be decoupled locally with ≥0.1 µF ceramic capacitor to suppress switching noise |
Key Features
| Feature | Design Value |
|---|---|
| Positive-edge triggering | Ensures deterministic sampling of D inputs only at defined CLK transitions - eliminates metastability risk from asynchronous data changes |
| Asynchronous clear (CLR) | Allows immediate, clock-independent reset of all six registers - essential for system initialization and fault recovery sequences |
| Wide VCC range (2–6 V) | Permits direct integration into mixed-supply systems without external voltage translation - reduces BOM count and layout complexity |
| Low ICC (≤80 µA) | Minimizes standby power in always-on control modules - critical for thermally constrained avionics enclosures |
| −55°C to +125°C operation | Validated performance across full military temperature range - eliminates derating calculations for high-temperature flight control units |

FAQ
What is the maximum clock frequency supported by JM38510/65307BEA?
JM38510/65307BEA supports a maximum clock frequency of 25 MHz at VCC = 4.5 V and TA = 25°C, as specified in the timing characteristics table. At 6 V supply, fmax increases to 29 MHz under the same conditions. These values assume proper load capacitance (CL = 50 pF) and meet setup/hold timing margins - actual system-level frequency may be limited by PCB trace delays and fanout.
Does JM38510/65307BEA require external pull-up or pull-down resistors on unused inputs?
Yes, JM38510/65307BEA requires all unused inputs to be held at VCC or GND to prevent floating nodes that could cause excessive ICC or erratic switching. This requirement is explicitly stated in the TI application report SCBA004 and applies to all HC-family devices. Leaving inputs unconnected risks increased power consumption and potential logic contention.
Is JM38510/65307BEA radiation-hardened, and what is its total ionizing dose (TID) rating?
Yes, JM38510/65307BEA is radiation-hardened and certified to MIL-PRF-38535 Class B. Its total ionizing dose (TID) rating is 100 krad(Si), verified per MIL-STD-883 Method 1019. This qualification makes it suitable for low-earth orbit and geosynchronous satellite applications where cumulative radiation exposure exceeds commercial-grade limits.
What is the absolute maximum supply voltage rating for JM38510/65307BEA?
The absolute maximum supply voltage for JM38510/65307BEA is −0.5 V to +7 V, as defined in the Absolute Maximum Ratings table. Operation beyond this range risks permanent damage. Recommended operating range remains 2 V to 6 V; sustained use at 7 V is not allowed even briefly, and negative voltage below −0.5 V violates clamp diode limits.
Can JM38510/65307BEA directly drive LED indicators without current-limiting resistors?
No, JM38510/65307BEA cannot safely drive LEDs without series current-limiting resistors. Its output drive is rated for ±4 mA at 5 V, while typical indicator LEDs require 10–20 mA. Exceeding the ±25 mA absolute maximum output current (IO) risks latchup or permanent damage. A minimum 330 Ω resistor is required for safe 5 V LED operation.
