Product details

Overview

TIBPAL16R6-15MJ from Texas Instruments is a military-grade, high-performance programmable array logic (PAL) device with registered 3-state outputs. It features 8 dedicated inputs, 6 registered output pins (Q), 2 I/O bidirectional ports, and a maximum propagation delay of 15 ns at 5 V. Designed for use in legacy aerospace, defense, and industrial control systems requiring deterministic timing and radiation-tolerant packaging.

For engineers reviewing the TIBPAL16R6-15MJ datasheet, TIBPAL16R6-15MJ pinout, TIBPAL16R6-15MJ application, or TIBPAL16R6-15MJ equivalent, key selection criteria include its −55°C to 125°C operating range, ceramic DIP (J) package, 50 MHz max clock frequency, and compatibility with TI's IMPACT-X™ programming algorithms for military PAL devices.

Technical Context

The TIBPAL16R6-15MJ implements a fixed 32 × 64 AND-OR logic array with eight dedicated input lines and six registered D-type flip-flops clocked by a single CLK input. Its architecture supports synchronous state retention via edge-triggered registers and enables output control through an active-low OE (output enable) signal.

All six Q outputs are 3-state buffers with guaranteed VOL ≤ 0.5 V at IOL = 12 mA and VOH ≥ 2.4 V at IOH = −2 mA. Power-up clear forces all register outputs high (logic 1), though output pins default low due to internal pull-down behavior during reset - a defined characteristic for registered PALs in this family.

Key Specifications

Parameter	Value and Actual Design Meaning
Propagation delay	Max 15 ns - ensures sub-67 MHz system timing margin for combinatorial paths between inputs and registered outputs.
Max clock frequency	50 MHz - defines upper limit for synchronous state transitions without violating setup/hold timing.
Supply voltage range	4.5 V to 5.5 V - compatible with standard 5 V TTL logic rails and accommodates supply droop in ruggedized systems.
Operating temperature	−55°C to 125°C - qualified for full military environmental stress screening per MIL-STD-883.
I/O drive strength	IOL = 12 mA / IOH = −2 mA - sufficient to directly interface with legacy TTL loads without external buffering.
Input count	8 dedicated inputs - provides fixed routing for address decoding, status aggregation, or control signal conditioning.
Registered outputs	6 Q outputs with D-flip-flop logic - enables synchronous data latching, state machine implementation, and glitch-free output updates.

Pinout & Package

Ceramic Dual In-line Package (CDIP), 20-pin, 300-mil body width, hermetically sealed with solderable tin-lead (SNPB) leads. Designed for high-reliability mounting in vibration-prone or thermally cycled environments.

Pin/Terminal	Circuit Role	Design Meaning
1	CLK	Positive-edge clock input controlling all six registered outputs; requires clean, monotonic transition to avoid metastability.
2–9	I	Dedicated input pins (I₂–I₉); no internal feedback - used for primary logic inputs such as address bits or command signals.
10	GND	Ground reference for all internal logic and I/O structures; must be low-impedance connection in PCB layout.
11	OE	Active-low output enable controlling all six Q outputs and two I/O ports; disables outputs to high-impedance state when high.
12, 14–19	Q / I/O	Pins 12, 14–17: Registered Q outputs; Pins 18–19: Bidirectional I/O ports - each supports input sensing or 3-state output driving under OE control.
20	VCC	+5 V power supply; decoupling capacitor (0.1 µF ceramic) required within 10 mm of pin for noise immunity.

Key Features

Feature	Design Value
Power-up clear	Resets all six Q outputs to logic high on power application - eliminates undefined startup states in safety-critical sequencers.
Military temperature rating	Qualified from −55°C to 125°C - enables deployment in avionics bays, engine control units, and space-qualified payloads.
Hermetic ceramic DIP	CDIP (J) package with glass-sealed leads - prevents moisture ingress and ensures long-term reliability in humid or corrosive atmospheres.
IMPACT-X™ architecture	Advanced Low-Power Schottky process with titanium-tungsten fuses - delivers stable programming retention over 20+ years in storage.
3-state registered outputs	Six Q outputs + two I/O ports support bus-sharing topologies - allows integration into shared data/address buses without external transceivers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar programmable logic applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TIBPAL16R6-15MFKB	LCCC (FK) package instead of CDIP (J); same logic array, timing, and programming algorithm.	Better thermal dissipation and higher vibration resistance; requires surface-mount assembly instead of through-hole.	Select for new designs targeting automated SMT production and improved mechanical robustness.
TIBPAL16R6-12MJ	12 ns propagation delay (vs. 15 ns); otherwise identical pinout, function, and military qualification.	Enables tighter timing margins in high-speed control loops; consumes slightly more power due to faster internal gates.	Choose when system-level timing budget requires <12 ns path delay and power increase is acceptable.

Compared with TIBPAL16R6-15MJ, the FK-packaged alternative offers superior mechanical stability but demands rework of PCB assembly processes, while the -12MJ variant trades 3 ns of delay for increased static current - both retain full functional and programming equivalence.

FAQ

What is the maximum clock frequency supported by the TIBPAL16R6-15MJ?

The TIBPAL16R6-15MJ supports a maximum clock frequency of 50 MHz under recommended operating conditions (VCC = 4.5 V to 5.5 V, TA = −55°C to 125°C). This specification is verified per TI's SRPS018B datasheet, and applies to the CLK input driving the six internal D-type flip-flops. Exceeding this frequency risks setup/hold violations and metastability in the TIBPAL16R6-15MJ's registered outputs.

Does the TIBPAL16R6-15MJ require special programming equipment or software?

Yes - the TIBPAL16R6-15MJ must be programmed using TI-compatible IMPACT-X™ algorithms corresponding to the TIBPAL16R6-12C specification, regardless of date code. Standard commercial PAL programmers supporting TI military PALs (e.g., Data I/O PS-2000 with appropriate firmware) are required. Programming voltage and pulse timing differ from commercial variants, and incorrect settings may permanently damage the TIBPAL16R6-15MJ.

What is the meaning of "Power-Up Clear" in the TIBPAL16R6-15MJ datasheet?

Power-Up Clear is a built-in feature of the TIBPAL16R6-15MJ that forces all six registered Q outputs to logic high immediately after VCC reaches valid operating level. However, due to internal output buffer design, the physical pins go low during this state - a defined behavior documented in TI's SRPS018B. This ensures deterministic initialization without external reset circuitry in the TIBPAL16R6-15MJ.

Can the TIBPAL16R6-15MJ be used in place of a TIBPAL16R4-15MJ?

No - the TIBPAL16R6-15MJ and TIBPAL16R4-15MJ have different logic architectures: the former provides 6 registered outputs and 2 I/O ports, while the latter provides 4 registered outputs and 4 I/O ports. Their pinouts differ (e.g., Q count and I/O allocation), and their fuse maps are incompatible. Substitution would require redesign of both logic equations and PCB layout for the TIBPAL16R6-15MJ.

Is the TIBPAL16R6-15MJ RoHS compliant?

No - the TIBPAL16R6-15MJ uses SnPb (tin-lead) lead finish and is explicitly marked "No" for RoHS compliance in TI's official packaging addendum. It is intended for use in legacy military and aerospace systems where exemption from RoHS Directive 2011/65/EU applies under Annex III categories 7a and 8. Aetrix Electronics supplies only fully traceable, original TI-manufactured TIBPAL16R6-15MJ units with certified lot documentation.
