Product details
Overview
JM38510/65761BRA from Texas Instruments is a military-grade octal buffer/line driver with 3-state outputs, designed for high-reliability bus interface applications in aerospace and defense systems. It operates from 4.5 V to 5.5 V, delivers ±6-mA output drive at 5 V, exhibits typical propagation delay of 12 ns, and supports −55°C to +125°C operation in a 20-pin CDIP package.
For engineers reviewing the JM38510/65761BRA datasheet, JM38510/65761BRA pinout, JM38510/65761BRA application, or JM38510/65761BRA equivalent, key selection considerations include its dual 3-state enable (OE1/OE2) NOR logic, data-flow-through pinout (inputs on one side, outputs on the other), TTL-compatible inputs, and low 80-µA max ICC power consumption in military temperature range.
Technical Context
This device implements eight independent non-inverting buffers, each with a 2-input NOR gate controlling 3-state output enable. When either OE1 or OE2 is high, all eight Y outputs enter high-impedance state-no internal pull-ups or pull-downs are present. The architecture enables direct system-bus interfacing without external termination.
It belongs to the SN54HCT541 family and uses HCT (High-Speed CMOS with TTL input thresholds) logic, ensuring compatibility with legacy TTL signal levels while delivering CMOS power efficiency. Input voltage thresholds are fixed at VIH = 2.0 V min and VIL = 0.8 V max across 4.5–5.5 V supply, with input current limited to ±1 µA max.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures robust operation across wide military-grade rail tolerance. |
| Operating Temperature | −55°C to +125°C - Qualified for extended-range aerospace and defense platforms. |
| Propagation Delay | 12 ns typical at 5.5 V - Enables reliable timing in 20–25 MHz bus cycles. |
| Output Drive | ±6 mA at 5 V - Sufficient to drive 15 LSTTL loads directly without buffering. |
| Input Compatibility | TTL-voltage compatible - Interfaces seamlessly with legacy 5-V TTL logic families. |
| Quiescent Current | 80 µA max ICC - Supports low-power standby modes in mission-critical subsystems. |
| 3-State Enable Logic | 2-input NOR (OE1, OE2) - Allows flexible bus arbitration using either or both enables. |
Pinout & Package
Package: 20-pin Ceramic Dual In-line Package (CDIP), hermetically sealed, J suffix per TI package drawing, suitable for high-reliability board-level mounting with through-hole soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | A1–A8 Inputs | True-buffer data inputs; TTL-compatible, low-input-current (≤1 µA) nodes. |
| 9 | GND | Signal ground reference for all I/O and internal logic; must be low-impedance. |
| 10, 20 | VCC | Power supply pins - dual VCC connections reduce supply inductance in high-speed switching. |
| 11, 19 | OE1, OE2 | Active-high 3-state enable inputs; NOR logic - either high disables all outputs. |
| 12–18 | Y1–Y8 Outputs | Non-inverting 3-state outputs; ±6-mA drive, high-impedance when enabled off. |
| 19 | A1 (repeated) | Confirmed as A1 per top-view diagram - pin 19 is A1, not duplicate; layout follows data-flow-through convention. |
Key Features
| Feature | Design Value |
|---|---|
| Data-flow-through pinout | Inputs (A1–A8) on left side, outputs (Y1–Y8) on right side - simplifies PCB routing and minimizes crosstalk in dense backplane layouts. |
| Dual 3-state enable (OE1/OE2) | NOR logic allows independent or combined bus control - supports multi-master arbitration without external logic. |
| TTL-compatible inputs | VIH = 2.0 V min / VIL = 0.8 V max - eliminates level-shifting when interfacing with legacy 5-V TTL peripherals. |
| Low ICC quiescent current | 80 µA max - reduces thermal load and extends battery life in portable avionics subsystems. |
| Military QML-38535 qualification | Complies with MIL-PRF-38535 Class B flow - includes screening for burn-in, temperature cycling, and lot acceptance testing. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54HCT541J | Same die, identical electrical specs and pinout; differs only in marking and internal lot traceability per QML-38535 flow. | No functional difference - both qualified to same MIL-PRF-38535 Class B requirements and operating range. | Select SNJ54HCT541J if sourcing from standard TI military catalog; JM38510/65761BRA indicates specific DSCC drawing compliance. |
| SN54HCT541J | Same silicon and package; lacks formal QML-38535 certification documentation and screening records. | Not approved for Class B space/aerospace programs requiring full DSCC traceability and test reports. | Use only in non-certified prototypes or commercial-grade derivatives where full military qualification is not mandated. |
Compared with SNJ54HCT541J, JM38510/65761BRA carries explicit DSCC drawing number traceability and is designated under JAN specification; compared with SN54HCT541J, it adds full QML-38535 Class B screening-critical for flight hardware where process control and lot-level reliability data are contractually required.

FAQ
What is the absolute maximum supply voltage rating for JM38510/65761BRA?
The absolute maximum supply voltage for JM38510/65761BRA is −0.5 V to 7 V, as specified in the Absolute Maximum Ratings table. Exceeding this range may cause permanent damage. For reliable operation, the recommended supply voltage remains 4.5 V to 5.5 V. This margin allows for transient spikes but does not imply functional operation beyond 5.5 V. Always verify decoupling and transient suppression in JM38510/65761BRA designs.
Does JM38510/65761BRA support hot-swap or live-insertion capability?
JM38510/65761BRA does not include built-in hot-swap protection circuitry such as slew-rate control or undervoltage lockout. Its 3-state outputs can be controlled externally via OE1/OE2 to manage bus contention during insertion, but the device itself lacks I²t-rated current limiting or soft-start features. System-level hot-swap implementation requires external FETs or dedicated hot-swap controllers. JM38510/65761BRA's design assumes controlled power sequencing per MIL-STD-1399 guidelines.
What is the meaning of "JM38510/65761BRA" in the context of military specifications?
"JM38510/65761BRA" denotes a Joint Army-Navy (JAN) qualified device under MIL-PRF-38535, where "JM" indicates JAN microcircuit, "38510" references the generic specification, "65761" is the specific drawing number for the HCT541 function, and "BRA" specifies the CDIP package variant with Class B screening. This full designation ensures traceability to DSCC-approved manufacturing flow and test records-distinct from commercial SN74HCT541 or even SNJ54HCT541J without drawing-specific marking. JM38510/65761BRA is fully documented under this identifier.
Can JM38510/65761BRA drive a 50-Ω transmission line directly?
No, JM38510/65761BRA is not designed for direct 50-Ω line driving. Its ±6-mA output drive at 5 V yields ~833 Ω effective source impedance (5 V / 6 mA), making it suitable for LSTTL fan-out or short PCB traces-not controlled-impedance RF or high-speed serial links. For 50-Ω interfaces, external series termination or dedicated line drivers (e.g., TI's SN65LVDS series) are required. JM38510/65761BRA's 12-ns tpd reflects performance into capacitive loads ≤50 pF, not transmission-line matching.
Is there a RoHS-compliant version of JM38510/65761BRA available?
No RoHS-compliant version of JM38510/65761BRA exists. As a hermetic ceramic DIP (CDIP-J), it uses lead-based solder seals and is exempt from RoHS under EU Directive 2011/65/EU Annex III for high-reliability aerospace and defense applications. TI's packaging addendum confirms "TBD" for eco plan and "Call TI" for lead/ball finish-indicating non-RoHS construction. Alternate RoHS-compliant packages (e.g., SN74HCT541DBR) exist but lack military qualification, temperature range, and hermeticity. JM38510/65761BRA remains intentionally non-RoHS to preserve reliability.
