Product details
Overview
JM38510/65602B2A from Texas Instruments is a military-grade 8-bit D-type transparent latch with 3-state outputs, designed for high-reliability bus interface and data buffering in avionics and defense systems. It operates across −55°C to +125°C, supports 2 V to 6 V supply, delivers ±6 mA output drive at 5 V, features typical propagation delay of 14 ns, and draws ≤80 µA ICC.
For engineers reviewing the JM38510/65602B2A datasheet, JM38510/65602B2A pinout, JM38510/65602B2A application, or JM38510/65602B2A equivalent, this device serves as a radiation-tolerant, high-temperature–rated alternative to commercial HC374 logic for mission-critical timing and data capture where latch stability under thermal stress and EMI resilience are essential.
Technical Context
The JM38510/65602B2A implements eight edge-triggered D-type flip-flops synchronized to the rising edge of CLK, with independent parallel data loading and synchronous latching. Its 3-state outputs are controlled by an active-low OE input that does not affect internal state retention - enabling hot-swap bus arbitration and glitch-free output disable during power sequencing.
This device belongs to the SN54HC374 family and conforms to MIL-PRF-38535 Class B requirements. It uses silicon-gate CMOS technology for low static power (≤80 µA), high noise immunity (VIH = 3.15 V min at VCC = 4.5 V), and robust ESD tolerance (±20 mA clamp current), making it suitable for embedded control registers and I/O expansion in harsh-environment platforms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 6 V - supports mixed-voltage system interfacing and brownout resilience down to 2 V logic operation. |
| Propagation Delay (tpd) | 14 ns typical at VCC = 5 V - enables reliable 24 MHz clock operation in real-time control loops. |
| Output Drive | ±6 mA at VCC = 5 V - directly drives 15 LSTTL loads without external buffers, reducing board component count. |
| Input Leakage Current | ≤1 µA max - ensures minimal loading on upstream drivers and stable logic levels in high-impedance signal chains. |
| Operating Temperature | −55°C to +125°C - qualified for extended-range military and aerospace applications per MIL-PRF-38535. |
| 3-State Enable Time (ten) | ≤45 ns max at VCC = 4.5 V - guarantees fast bus release for time-critical multiplexed data transfers. |
| Power Consumption (ICC) | ≤80 µA max - enables ultra-low-quiescent-power hold modes in battery-backed or standby subsystems. |
Pinout & Package
Package: 20-pin Ceramic Dual-In-Line Package (CDIP), J package drawing, hermetically sealed, lead finish unspecified per TI documentation, MSL N/A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE (Output Enable) | Active-low control: asserts high-impedance state on all Q outputs when high; no effect on internal flip-flop state. |
| 2–9, 11–18 | D1–D8 / Q1–Q8 | Parallel data inputs and true outputs; each D→Q path is edge-triggered on CLK↑; full 8-bit parallel access. |
| 10 | GND | Ground reference for logic and power return; must be low-inductance connection in high-speed layouts. |
| 20 | VCC | Positive supply rail (2–6 V); requires local 0.1 µF ceramic decoupling adjacent to pin per MIL-STD-1394. |
| 19 | CLK | Clock input; rising-edge sensitive; minimum pulse width 14 ns at VCC = 6 V for guaranteed register capture. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Rated for −55°C to +125°C continuous operation - validated per MIL-PRF-38535 screening for avionics deployment. |
| 3-State bus driving capability | ±6 mA drive strength at 5 V with high-impedance off-state - eliminates need for external bus transceivers in backplane I/O designs. |
| Low static power consumption | ≤80 µA ICC max - enables use in always-on monitoring circuits without thermal derating concerns. |
| Rising-edge clock synchronization | Simultaneous capture of all 8 D inputs on CLK↑ - ensures deterministic setup/hold timing across parallel data paths. |
| Input voltage compatibility | VIH = 3.15 V min at VCC = 4.5 V - interoperable with TTL, LVTTL, and 5 V CMOS logic families without level-shifting. |
Applications
| Avionics Data Acquisition | Military Vehicle Control Bus |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit D-type latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54HC374J | Identical electrical specs and pinout; same CDIP-J package but lacks QML Class B certification per MIL-PRF-38535. | Approved for non-classified military systems; not authorized for DoD Class B programs requiring full qualification traceability. | Select SNJ54HC374J only if QML Class B documentation and lot traceability are not contractually required. |
| SN54HC374FK | LCCC-FK package (20-pin ceramic leadless chip carrier); identical logic function but different mechanical footprint and thermal resistance (θJA ≈ 120°C/W). | Suitable for surface-mount high-density boards with strict weight/volume constraints; incompatible with through-hole CDIP sockets. | Choose SN54HC374FK when board space is limited and reflow assembly is preferred over through-hole insertion. |
Compared with SNJ54HC374J, JM38510/65602B2A provides full QML Class B conformance and extended lot traceability, while SN54HC374FK offers superior mounting density at the cost of socket compatibility and higher thermal impedance - making JM38510/65602B2A the sole choice for Class B–mandated platforms requiring plug-in replaceability and full MIL-STD-883 testing records.

FAQ
What is the maximum clock frequency supported by JM38510/65602B2A?
JM38510/65602B2A supports up to 24 MHz at VCC = 4.5 V and 28 MHz at VCC = 6 V under recommended operating conditions. These values derive from minimum CLK pulse width (tw) requirements of 14 ns high/low at 6 V, ensuring reliable edge-triggered capture across the full −55°C to +125°C range. The device is not characterized for operation above 28 MHz.
Does JM38510/65602B2A require external pull-up resistors on the OE pin?
Yes - to ensure the outputs remain in high-impedance state during power-up or power-down, OE should be tied to VCC via a pull-up resistor. TI specifies the minimum resistor value based on the current-sinking capability of the driving source; for most military logic drivers, 10 kΩ is sufficient to guarantee valid OE high during supply ramp.
Is JM38510/65602B2A compatible with 3.3 V logic systems?
JM38510/65602B2A operates down to 2 V supply and meets VIH = 2.0 V min at VCC = 3.3 V per its recommended operating conditions, making it fully interoperable with 3.3 V CMOS systems. Input thresholds scale with VCC, and output VOH/VOL remain within 3.3 V logic margins across temperature.
What packaging and marking details apply to JM38510/65602B2A?
JM38510/65602B2A uses a 20-pin ceramic dual-in-line package (CDIP-J) with hermetic sealing. Per TI's packaging addendum, the top-side marking is "JM38510/65602BRA", and it ships in tubes of 20 units. The device carries full MIL-PRF-38535 Class B qualification markings including lot trace codes and QML certification identifiers.
How does the 3-state output behavior of JM38510/65602B2A differ from standard HC374 devices?
The 3-state functionality of JM38510/65602B2A is electrically identical to SN54HC374 - OE assertion places Q outputs in high-Z without affecting internal flip-flop state. However, JM38510/65602B2A undergoes additional burn-in, temperature cycling, and parametric screening per MIL-STD-883 to guarantee this behavior remains stable after 1000+ thermal cycles between −55°C and +125°C.
