Product details

Overview

TIBPAL16R4-15MJB from Texas Instruments is a military-grade, registered programmable array logic (PAL) device with 8 dedicated inputs, 4 registered 3-state outputs (Q), and 4 bidirectional I/O ports. It delivers 15 ns maximum propagation delay, operates across −55°C to 125°C, and features power-up clear that initializes all register outputs high while driving output pins low-enabling deterministic startup in avionics and ruggedized control systems.

For engineers reviewing the TIBPAL16R4-15MJB datasheet, TIBPAL16R4-15MJB pinout, TIBPAL16R4-15MJB application, or TIBPAL16R4-15MJB equivalent, this page provides verified functional identity, military-qualified timing behavior, J-package pin validation, registered logic architecture details, and direct alternatives for legacy system sustainment and obsolescence mitigation.

Technical Context

The TIBPAL16R4-15MJB implements a fixed-architecture PAL with a 32 × 64 AND-OR array feeding four D-type flip-flops clocked by a single CLK input. All Q outputs are individually controllable via a shared OE (output enable) signal, supporting bus-oriented 3-state operation with guaranteed 7–12 ns enable/disable times.

It uses Advanced Low-Power Schottky (ALS) technology with titanium-tungsten fuses, enabling reprogrammability only during initial programming-not in-system-and requiring TI-specific algorithms (TIBPAL16R4-12C for date codes pre-9616A; TIBPAL16R4-10C for 9616A+). Its logic diagram confirms dedicated feedback paths from Q outputs to the AND array, supporting synchronous state-machine implementation.

Key Specifications

Parameter	Value and Actual Design Meaning
Propagation Delay	15 ns max - ensures reliable timing closure up to 50 MHz clock frequency in synchronous logic designs.
Operating Temperature	−55°C to 125°C - qualified for full military temperature range, suitable for aerospace and defense hardware.
Supply Voltage	4.5 V to 5.5 V - compatible with standard 5 V TTL systems; no 3.3 V operation supported.
Output Drive	IOL = 12 mA / IOH = −2 mA - sufficient to drive multiple TTL loads without external buffers.
Input Count	8 dedicated inputs + CLK + OE - total of 10 active input terminals for combinational and sequential logic definition.
Registered Outputs	4 Q outputs with edge-triggered D flip-flops - enables synchronous state retention and pipeline staging.
3-State Control	Single OE pin controlling all Q and I/O ports - simplifies bus arbitration and reduces control signal routing.

Pinout & Package

Ceramic Dual-In-Line Package (CDIP), 300-mil body, 20-pin, hermetically sealed with solderable tin-lead (SNPB) leads. Designed for high-reliability, high-temperature PCB mounting with through-hole soldering.

Pin/Terminal	Circuit Role	Design Meaning
1	CLK	Positive-edge clock input synchronizing all four D flip-flops; requires ≥9 ns high pulse and ≥10 ns low pulse per cycle.
2–9	I	8 dedicated asynchronous inputs feeding the AND-OR array; no internal pull-ups or latching.
10	GND	Ground reference for all logic and power domains; must be low-inductance connection in high-speed layouts.
11	VCC	+5 V supply pin; decoupling capacitor (0.1 µF ceramic) required within 10 mm for stable ALS switching.
12–13	I/O	Bidirectional ports with 3-state capability; function as inputs when OE high, outputs when OE low.
14–17	Q	4 registered outputs - each is the Q output of a D flip-flop; synchronized to CLK↑ and controlled by OE.
18–19	I/O	Additional bidirectional ports identical in function to pins 12–13; support expanded data path width.
20	OE	Active-low output enable controlling all Q and I/O port drivers; asserts high-impedance state when high.

Key Features

Feature	Design Value
Power-Up Clear	Resets all Q outputs to logic high at power-on, while forcing physical pins low-ensuring safe default bus state before firmware initialization.
Military Qualification	Screened to MIL-PRF-38535 Class B standards with 5962-8515512RA SMD number-certified for flight-critical and ground-vehicle applications.
ALS Technology	Combines low power consumption (ICC = 170–220 mA typical) with high speed, eliminating need for external cooling in dense logic assemblies.
Fuse-Based Programming	One-time programmable titanium-tungsten fuses provide permanent, radiation-tolerant configuration storage-no volatility or refresh required.
Feedback Architecture	Dedicated feedback paths from Q outputs to AND array enable compact implementation of counters, shift registers, and finite-state machines.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TIBPAL16R4-15MFKB	LCCC (FK) package instead of CDIP (J); same logic, timing, and electrical specs; different mechanical footprint and thermal mass.	Preferred for surface-mount, high-density boards where hermetic sealing and thermal cycling resistance outweigh through-hole assembly requirements.	Select when board space constraints or automated assembly favor leadless ceramic chip carrier over through-hole DIP.
TIBPAL16R6-15MJB	6 registered outputs (Q) and 2 I/O ports vs. 4 Q + 4 I/O; identical propagation delay, temperature range, and programming model.	Used where additional registered outputs are needed for wider state registers or parallel control paths without adding second device.	Choose when design requires more synchronous outputs and can accommodate reduced I/O count; no pin compatibility.

Compared with TIBPAL16R4-15MJB, the FK variant offers superior high-frequency layout stability but requires rework of PCB land pattern and reflow profile, while the R6 variant increases registered output count at the expense of I/O flexibility-neither is pin-compatible, but both share identical programming flow and military qualification.

FAQ

What is the correct programming algorithm for TIBPAL16R4-15MJB?

TIBPAL16R4-15MJB devices with date code 9616A or later require the TIBPAL16R4-10C programming algorithm; units prior to 9616A must use TIBPAL16R4-12C. Using the wrong algorithm risks fuse damage or incomplete programming. The SMD number 5962-8515512RA confirms this part's military specification alignment and programming dependency.

Does TIBPAL16R4-15MJB support 3.3 V operation?

No, TIBPAL16R4-15MJB is strictly a 5 V device with recommended VCC of 4.5 V to 5.5 V. It does not support 3.3 V supply or mixed-voltage interfacing. Input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) and output levels (VOH = 2.4 V min at −2 mA) are defined only for 5 V operation, and operation outside this range violates absolute maximum ratings.

Is TIBPAL16R4-15MJB pin-compatible with other PAL16R4 variants?

TIBPAL16R4-15MJB shares identical pinout with all TIBPAL16R4-15M variants in J, W, and FK packages-including TIBPAL16R4-15MFKB and TIBPAL16R4-15MWB-as confirmed by the "J OR W PACKAGE" and "FK PACKAGE" diagrams in the SRPS018B datasheet. However, mechanical package differences prevent direct socket substitution without PCB redesign.

What does "Power-Up Clear" mean for TIBPAL16R4-15MJB?

Power-Up Clear forces all four Q register outputs to logic high immediately after VCC reaches valid level, while simultaneously driving the physical output pins low until the first CLK edge. This dual-state behavior ensures predictable bus initialization-critical for preventing glitches on shared data lines during system boot in TIBPAL16R4-15MJB-based designs.

Can TIBPAL16R4-15MJB be reprogrammed after initial programming?

No, TIBPAL16R4-15MJB uses one-time-programmable titanium-tungsten fuses. Once programmed, its logic function is permanently fixed. Reprogramming is not possible-even with voltage cycling or UV exposure-as there is no erasure mechanism. Field updates require physical device replacement, consistent with all IMPACT™ PAL devices.
