Product details
Overview
JM38510/50504BLA from Texas Instruments is a military-grade, 24-pin ceramic dual in-line package (CDIP) registered programmable array logic (PAL) device with eight registered 3-state outputs, 12 inputs, and operation across −55°C to 125°C. It delivers 41.6 MHz maximum clock frequency without feedback, 120–180 mA supply current, and supports preload and power-up clear for deterministic state initialization in avionics and missile guidance systems.
For engineers reviewing the JM38510/50504BLA datasheet, JM38510/50504BLA pinout, JM38510/50504BLA application, or JM38510/50504BLA equivalent, this device serves as a drop-in replacement for legacy TIBPAL20R8-20M in high-reliability digital control, real-time signal conditioning, and radiation-tolerant logic sequencing where guaranteed timing, register preloading, and extended temperature stability are required.
Technical Context
The JM38510/50504BLA implements an IMPACT™ PAL architecture with a 40 × 64 programmable AND array feeding eight D-type flip-flops, each with asynchronous preload and synchronous clocking via dedicated CLK and OE pins. Its logic structure supports combinatorial output generation and registered state retention with edge-triggered updates.
It features a dedicated power-up reset circuit that forces all registered outputs low at VCC ramp-up, and supports individual register preload using VIHH (10.25–10.75 V) on Pin 13 and clock strobing - enabling deterministic test initialization without full state-machine traversal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Type | Registered PAL with 8 Q outputs and 3-state I/O capability |
| Max Clock Frequency | 41.6 MHz without feedback - sets hard upper bound on synchronous state update rate |
| Supply Current (ICC) | 120–180 mA at VCC = 5.5 V - defines power rail sizing and thermal management requirements |
| Operating Temperature | −55°C to 125°C - qualified for MIL-PRF-38535 Class B applications including flight-critical systems |
| Propagation Delay (tpd) | 8–15 ns (CLK→Q), 12–25 ns (I/O→O/I/O) - enables sub-25 ns cycle timing in tightly coupled control loops |
| Input Voltage Range | VIL = 0.8 V, VIH = 2.0 V - compatible with standard TTL and 5 V CMOS logic families |
| Output Drive | IOL = 12 mA, IOH = −2 mA - sufficient to drive multiple TTL loads or terminated transmission lines |
Pinout & Package
Package: 24-pin ceramic dual in-line package (CDIP), JT outline per MIL-STD-1835, hermetically sealed, lead finish per MIL-STD-1835.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK | Asynchronous clock input controlling all eight registers; rising-edge sensitive |
| 2–13 | I1–I12 | Dedicated input pins feeding programmable AND array; no internal pull-ups |
| 14 | GND | Signal ground reference for all logic and power domains |
| 15–22 | I/O1–I/O8 | Bidirectional 3-state I/O ports with configurable direction via fuse map; support bus sharing |
| 23 | OE | Active-low output enable controlling 3-state buffer drivers for all eight I/O pins |
| 24 | VCC | +5 V power supply pin; requires local 0.1 µF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Power-Up Clear | Guarantees all registered outputs initialize to logic low at power-on - eliminates undefined startup states in safety-critical sequencers |
| Individual Register Preload | Allows any Q output to be forced to high or low before test execution - reduces functional test time by bypassing state traversal |
| Military Temperature Range | Validated operation from −55°C to 125°C - meets MIL-PRF-38535 screening requirements for aerospace deployment |
| High-Speed Registered Logic | 41.6 MHz max clock rate with 8 ns typical CLK→Q delay - supports real-time control loop frequencies up to 20+ MHz |
| Hermetic CDIP Packaging | 24-pin ceramic DIP (JT) with glass-sealed leads - provides moisture resistance and long-term reliability in harsh environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar registered PAL applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TIBPAL20R8-20M | Same logic function, identical pinout, commercial-grade screening (not MIL-PRF-38535) | Lacks Class B qualification, limited to non-flight hardware or ground-test fixtures | Select when full military screening is not required and cost sensitivity dominates |
| 5962-8767102LA | Identical die, same JT package, but marked per JAN specification with different lot traceability | Used in legacy DoD contracts requiring JAN designation instead of JM prefix | Select only when contract documentation mandates JAN-qualified marking |
Compared with TIBPAL20R8-20M and 5962-8767102LA, JM38510/50504BLA provides verified Class B screening per MIL-PRF-38535, full lot traceability, and guaranteed performance over −55°C to 125°C - making it the sole choice for flight-certified hardware where process control and environmental robustness are non-negotiable.

FAQ
What is the operating temperature range specified for JM38510/50504BLA?
JM38510/50504BLA is characterized for operation from −55°C to 125°C per MIL-PRF-38535 Class B requirements. This full military temperature range is validated through temperature cycling, burn-in, and parametric testing - ensuring reliable functionality in extreme environmental conditions encountered in aerospace and defense platforms.
Does JM38510/50504BLA support register preload, and how is it implemented?
Yes, JM38510/50504BLA supports individual register preload. To preload a specific Q output, apply VIHH (10.25–10.75 V) to Pin 13, set the target output voltage (VIL or VIH) on its corresponding I/O pin, then pulse CLK (Pin 1). This allows deterministic initialization of any register state prior to functional testing - eliminating dependency on sequential state traversal.
What package type and pin count does JM38510/50504BLA use?
JM38510/50504BLA uses a 24-pin ceramic dual in-line package (CDIP) with JT outline per MIL-STD-1835. It is hermetically sealed, features glass-sealed leads, and complies with MIL-PRF-38535 mechanical and environmental requirements for high-reliability deployment.
How does the power-up clear function operate in JM38510/50504BLA?
JM38510/50504BLA incorporates an internal power-up reset circuit that forces all registered outputs low upon monotonic VCC ramp-up. This occurs within 1000 ns after VCC exceeds 1.5 V, ensuring deterministic initialization without external reset circuitry - critical for fail-safe behavior in flight-critical logic sequencers.
Is JM38510/50504BLA pin-compatible with commercial TIBPAL20R8 variants?
Yes, JM38510/50504BLA is pin-compatible with TIBPAL20R8-20M and other 24-pin JT-package TIBPAL20R8 devices. The pinout, electrical interface, and logic function are identical - enabling direct substitution in existing designs where military-grade screening and extended temperature operation are required.
