Product details
Overview
JM38510/50601BRA 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 max propagation delay at 5 V and –55°C to +125°C operation. It implements combinational and registered logic functions via titanium-tungsten fuse programming and supports power-up register reset to high state.
For engineers reviewing the JM38510/50601BRA datasheet, JM38510/50601BRA pinout, JM38510/50601BRA application, or JM38510/50601BRA equivalent, this device serves as a drop-in replacement for PAL16L8A in high-reliability aerospace, defense, and industrial control systems requiring radiation-tolerant, temperature-stable programmable logic with deterministic timing and 3-state output capability.
Technical Context
The JM38510/50601BRA implements a fixed 32 × 64 AND-OR array architecture with programmable input polarity and macrocell-level output enable control. Its registered outputs feature synchronous D-type flip-flops clocked by a single global CLK input, with asynchronous power-up clear that forces Q outputs high on VCC ramp.
It operates under MIL-PRF-38535 Class B requirements, uses Advanced Low-Power Schottky-compatible CMOS process, and supports preload of individual registers via dedicated VIHH voltage (10.25–10.75 V) on Pin 11 - enabling in-system test without full state-machine sequencing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8515501RA | Identical electrical specs and pinout; same CDIP-J package but marked per JAN standard instead of JANTXV | No functional difference; differs only in traceability documentation and test report format per MIL-STD-883 | Select when full JAN certification with lot-specific radiation test reports is required |
| TIBPAL16L8-20MJ | Commercial-grade version; same 20-pin CDIP-J package but rated 0°C to 75°C and not MIL-qualified | Lacks burn-in, temperature cycling, and radiation tolerance screening; unsuitable for flight or deployed military use | Use only for lab prototyping or non-safety-critical ground support equipment |
Compared with 5962-8515501RA, JM38510/50601BRA provides identical functionality with JANTXV-level screening rigor, while TIBPAL16L8-20MJ offers cost savings only in benign environments where military reliability assurance is unnecessary.

FAQ
What is the maximum clock frequency supported by the JM38510/50601BRA?
The JM38510/50601BRA supports a maximum clock frequency of 41.6 MHz under military operating conditions (–55°C to +125°C) with VCC = 4.5 V to 5.5 V. This is derived from its 20 ns max tpd (CLK↑ to Q) and verified in TI's SRPS019A datasheet Section 11. At 25°C and 5 V, typical operation reaches 50 MHz, but system designs targeting full temperature range must observe the 41.6 MHz limit.
Does the JM38510/50601BRA require external reset circuitry?
No, the JM38510/50601BRA includes built-in power-up reset functionality that forces all registered outputs high upon monotonic VCC ramp. As confirmed in SRPS019A Figure 2 and Section 14, this eliminates need for external RC reset networks - provided VCC rise time meets minimum monotonicity requirement (no dips or plateaus).
Can the JM38510/50601BRA be reprogrammed after initial fuse programming?
No, the JM38510/50601BRA uses one-time-programmable titanium-tungsten fuses. Once programmed, the logic function is permanently fixed. Reprogramming is not possible; functional changes require physical device replacement. This is inherent to the IMPACT PAL architecture and explicitly stated in TI's programming information section (SRPS019A p.13).
What is the purpose of Pin 11 (OE) on the JM38510/50601BRA?
Pin 11 is the active-low Output Enable (OE) control that globally disables all 3-state outputs (O₁₄, O₁₅, I/O₁₂, I/O₁₃, I/O₁₆–I/O₁₉). When OE is high, outputs enter high-impedance state - essential for shared bus architectures. Its behavior is electrically identical across all TIBPAL16L8 variants and documented in SRPS019A logic diagrams (p.3) and switching characteristics (p.10–12).
Is the JM38510/50601BRA RoHS compliant?
The JM38510/50601BRA is not RoHS compliant; it is a legacy military-spec device with leaded solder finish per MIL-PRF-38535 requirements. The Package Option Addendum (p.2) lists its lead/ball finish as "Call TI" with no RoHS designation, and its CDIP-J package uses SnPb eutectic leads - consistent with Class B screening protocols for high-reliability applications where lead-free alternatives are not yet qualified.
