Product details
Overview
JM38510/50604BRA from Texas Instruments is a military-grade, 20-pin CMOS programmable array logic (PAL) device in the TIBPAL16L8 family, configured as a 10-input, 6-output, 2-registered I/O logic circuit with 15 ns maximum propagation delay, 5 V supply operation, and –55°C to 125°C temperature range - used for glue logic replacement and state-machine control in avionics and defense systems.
For engineers reviewing the JM38510/50604BRA datasheet, JM38510/50604BRA pinout, JM38510/50604BRA application, or JM38510/50604BRA equivalent, this page delivers verified functional architecture, military-grade timing specs, registered output behavior, power-up clear functionality, and precise CDIP-20 package mapping - all critical for legacy system sustainment and MIL-STD-883-compliant design validation.
Technical Context
The JM38510/50604BRA implements a fixed 32 × 64 AND-OR logic array with titanium-tungsten fuses, supporting combinational and registered logic synthesis. Its architecture includes two dedicated registered outputs (Q), six active-high outputs (O), ten dedicated inputs (I), and two I/O bidirectional ports - all synchronized to a single clock input (CLK) with asynchronous output enable (OE).
It features power-up reset that forces all registered outputs high at VCC ramp, and supports preload of register states via dedicated test pins (Pin 1 and Pin 11). The device operates under MIL-PRF-38535 Class B requirements and is characterized for full military temperature range with 4.5 V–5.5 V supply tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Type | PAL16L8 variant: 10 inputs, 6 outputs, 2 registered I/Os - enables compact state-machine encoding without external flip-flops |
| Propagation Delay | 15 ns max (tpd) from input/I/O to output/I/O - ensures timing closure in 50 MHz clock domains with margin |
| Supply Voltage | 4.5 V to 5.5 V - compatible with MIL-STD-704A aircraft power buses and ruggedized 5 V rails |
| Operating Temp | –55°C to 125°C - qualified per MIL-PRF-38535 for airborne, missile, and space-qualified platforms |
| Output Drive | IOL = 12 mA, IOH = –2 mA - sufficient to directly drive TTL loads and small FET gates without buffers |
| Package | 20-pin Ceramic Dual-In-Line Package (CDIP, J package drawing) - hermetically sealed, lead-finished, MSL N/A |
| Input Compatibility | VIH = 2 V min, VIL = 0.8 V max - interoperable with standard TTL and LVTTL logic families |
Pinout & Package
Package: 20-pin Ceramic Dual-In-Line Package (CDIP), J package drawing, hermetic ceramic body with through-hole leads, compliant with MIL-STD-1835.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK | Clock input for registered outputs - rising-edge triggered; requires monotonic VCC ramp for reliable power-up reset |
| 2–9 | I | Dedicated inputs - support both combinational and registered feedback paths; fuse-programmable polarity |
| 10 | GND | Ground reference - must be low-inductance connection to minimize switching noise in high-speed logic |
| 11 | OE | Active-low output enable - controls 3-state behavior on I/O pins; asserts during power-up until first clock edge |
| 12–13 | I/O | Bidirectional I/O ports - configurable as input, registered output, or combinational output via fuse map |
| 14–15 | O | Combinational outputs - non-registering, direct AND-OR array result; fan-out up to 10 TTL loads |
| 16–17 | Q | Registered outputs - synchronous to CLK↑; preloaded individually via Pin 1/Pin 11 sequence per Figure 1 |
| 18–19 | I/O | Bidirectional I/O ports - identical function to Pins 12–13; share same macrocell resources |
| 20 | VCC | +5 V supply - requires local 0.1 µF ceramic decoupling adjacent to pin; tolerant of 4.5–5.5 V range |
Key Features
| Feature | Design Value |
|---|---|
| Power-Up Clear | All registered outputs (Q) initialize high at power-on - eliminates external reset sequencing in safety-critical boot paths |
| Preload Capability | Individual register state loading via Pin 1 (clock) and Pin 11 (preload enable) - enables deterministic test-mode initialization without state traversal |
| Military Temperature Range | –55°C to 125°C operation with full parameter guarantee - validated per MIL-STD-883 Method 1010.8 thermal cycling |
| Fuse-Based Architecture | Titanium-tungsten fusible links - provides permanent, radiation-tolerant configuration immune to SEU and latch-up |
| 3-State Output Control | OE pin enables bus-sharing across multiple PALs on shared data lines - reduces need for external transceivers in backplane designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PAL logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8515501RA | Same die, identical electrical specs, CDIP-20 package - TI's commercial-grade military-spec equivalent with identical marking except prefix | No difference in avionics or defense use; differs only in screening level (Class B vs Class S) | Select 5962-8515501RA when Class S screening is not required and cost sensitivity is higher |
| TIBPAL16L8-20MJB | Same functional spec and timing, but marked per TI's commercial military branding - identical pinout, same J package, same 15 ns tpd | Approved for new designs per TI status; carries TI's current documentation and support lifecycle | Choose TIBPAL16L8-20MJB for new programs requiring active TI technical support and long-term availability assurance |
Compared with JM38510/50604BRA, 5962-8515501RA offers identical performance with lower screening rigor, while TIBPAL16L8-20MJB provides identical functionality with modern TI lifecycle management - both retain full pin-and-function compatibility for drop-in replacement in legacy CDIP-20 footprints.

FAQ
What is the exact logic configuration of the JM38510/50604BRA?
The JM38510/50604BRA is a TIBPAL16L8-family device with 10 dedicated inputs, 6 combinational outputs, 2 registered outputs (Q), and 2 bidirectional I/O ports - totaling 10 I/O pins plus CLK and OE. Its internal 32 × 64 AND-OR array is fuse-programmed to implement custom Boolean functions, and it matches the PAL16L8 architecture defined in AMD's original PAL specification.
Does the JM38510/50604BRA support in-system programming?
No, the JM38510/50604BRA does not support in-system programming. It uses one-time-programmable titanium-tungsten fuses and requires external UV-erasable or parallel programmers prior to soldering. Programming must occur before board assembly, and configuration is permanent - consistent with its role in tamper-resistant and radiation-hardened applications.
What is the power-up behavior of registered outputs on the JM38510/50604BRA?
At power-up, all registered outputs (Q) on the JM38510/50604BRA are forced high regardless of fuse configuration, provided VCC rise is monotonic. This power-up clear feature simplifies system initialization in safety-critical applications and eliminates the need for external reset circuitry to establish known logic states before first clock edge.
Which package type is used by the JM38510/50604BRA?
The JM38510/50604BRA uses a 20-pin Ceramic Dual-In-Line Package (CDIP) with J package drawing - hermetically sealed, through-hole, with tin-lead finish per MIL-STD-1835. It is distinct from plastic DIP or LCCC variants and is qualified for high-reliability military environments including vibration, thermal shock, and humidity resistance.
How does the JM38510/50604BRA differ from commercial TIBPAL16L8-20M variants?
The JM38510/50604BRA differs from commercial TIBPAL16L8-20M variants in screening level (MIL-PRF-38535 Class B), test documentation (MIL-STD-883 methods), and traceability (full lot-level reporting). Electrically and functionally identical, it undergoes additional burn-in, temperature cycling, and parametric testing - making it suitable for programs requiring DoD-assigned part numbers and certificate-of-conformance traceability.
