Product details

Overview

JM38510/50607BRA from Texas Instruments is a military-grade, 20-pin registered PAL (Programmable Array Logic) device in the TIBPAL16R6 family, featuring 8 inputs, 6 registered 3-state outputs, and 2 I/O ports. It operates over −55°C to +125°C, delivers ≤30 ns propagation delay, supports up to 25 MHz clock frequency, and includes power-up reset that initializes all registers high. It is used in legacy aerospace and defense systems for custom logic implementation, state-machine control, and bus interface logic.

For engineers reviewing the JM38510/50607BRA datasheet, JM38510/50607BRA pinout, JM38510/50607BRA application, or JM38510/50607BRA equivalent, this page provides verified functional identity, military temperature-rated timing specs, registered output behavior, CDIP-20 package mapping, and direct alternatives with documented electrical and thermal differences.

Technical Context

The JM38510/50607BRA implements a fixed architecture with an AND-OR-inverter logic array feeding six D-type flip-flops clocked by a single global CLK input. All registered outputs are 3-state controllable via a common active-low OE (Output Enable) signal, enabling shared-bus applications without external bus transceivers.

It uses titanium-tungsten fuses for one-time programmability and Advanced Low-Power Schottky (ALPS) technology to achieve low static current (ICC ≤105 mA) while maintaining TTL-compatible voltage thresholds (VIH ≥2 V, VIL ≤0.8 V) and robust drive capability (IOL = 12 mA, IOH = −2 mA).

Key Specifications

Pin/Terminal	Circuit Role	Design Meaning
1	CLK	Global clock input - rising-edge triggered; requires monotonic VCC ramp for reliable power-up reset
2–9	I	Primary logic inputs - 8 dedicated inputs for product-term generation and feedback routing
10	GND	Ground reference - must be low-inductance connection to minimize noise coupling into registered logic
11	OE	Active-low output enable - controls 3-state behavior of all 6 registered outputs simultaneously
12–13	I/O	Bidirectional I/O ports - configurable as input or 3-state output; support feedback paths for sequential logic
14–19	Q	Registered outputs - 6 edge-triggered D-type flip-flop outputs, each 3-state enabled by OE
20	VCC	Positive supply - must be decoupled locally with 0.1 µF ceramic capacitor near pin

Key Features

Equivalent & Alternatives

The following parts are listed as comparable options for similar registered PAL applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
JM38510/50606BRA	TIBPAL16R4 variant: 8 inputs, 4 registered 3-state outputs, 4 I/O ports - smaller register count, identical timing and temp range	Suitable where fewer registered outputs are needed; lower pin utilization but same CDIP-20 footprint	Select when design requires only four registered outputs and two additional I/Os instead of six Qs and two I/Os.
JM38510/50608BRA	TIBPAL16R8 variant: 8 inputs, 8 registered 3-state outputs, zero I/O ports - higher output count, no bidirectional ports	Preferred for pure output expansion tasks without feedback requirements; lacks I/O flexibility of JM38510/50607BRA	Choose when full 8-output registration is required and feedback paths are handled externally or not needed.

Compared with JM38510/50606BRA and JM38510/50608BRA, the JM38510/50607BRA uniquely balances 6 registered outputs with 2 bidirectional I/O ports-enabling both state retention and internal feedback within a single device, reducing interconnect complexity in closed-loop control designs.

FAQ

What is the exact logic architecture of the JM38510/50607BRA?

The JM38510/50607BRA implements the TIBPAL16R6 architecture: an 8-input, 6-output registered PAL with 2 bidirectional I/O ports. It contains a fixed-sum-of-products array feeding six D-type flip-flops, all clocked by a single CLK input and controlled by a shared OE signal. Its structure is defined in TI's SRPS059A datasheet and matches the military-specification variant of the commercial TIBPAL16R6-30M.

Does the JM38510/50607BRA support in-system programming?

No, the JM38510/50607BRA does not support in-system programming. It is a one-time programmable (OTP) device using titanium-tungsten fuses. Programming must be performed prior to installation using a compatible PAL programmer (e.g., Data I/O PS-29 or BP Microsystems Series 4), and the configuration is permanent and non-volatile.

What is the significance of the "BRA" suffix in JM38510/50607BRA?

The "BRA" suffix denotes a specific manufacturing lot and screening configuration under MIL-PRF-38535: "B" indicates Class B quality level (full military screening), "R" specifies radiation hardness assurance per MIL-STD-883 TM 1019.1, and "A" identifies the revision level of the die and package assembly. This suffix confirms compliance with U.S. Department of Defense requirements for high-reliability applications.

Can JM38510/50607BRA replace commercial TIBPAL16R6-30M devices in existing designs?

Yes, the JM38510/50607BRA is the military-qualified equivalent of the commercial TIBPAL16R6-30M, sharing identical logic functionality, pinout, and AC/DC specifications. However, it adds extended temperature range (−55°C to +125°C), enhanced screening, and hermetic CDIP packaging-making it suitable for drop-in replacement where environmental ruggedness is required.

How does the power-up reset function behave on JM38510/50607BRA?

On power application, the JM38510/50607BRA asserts a built-in power-up reset that forces all six Q outputs to logic high, regardless of initial input states. This occurs only if VCC rise is monotonic; non-monotonic ramps may cause metastability. The reset is internal and requires no external components-critical for deterministic startup in safety-critical systems.
