Product details
Overview
TIBPAL16R8-12MFKB from Texas Instruments is a military-grade, 20-pin registered programmable array logic (PAL) device with eight registered 3-state outputs, 8 dedicated inputs, and a single clock input. It operates over −55°C to 125°C, delivers 56 MHz maximum frequency without feedback, exhibits 12 ns max propagation delay, and features preload capability and power-up clear for deterministic initialization in embedded control and legacy system upgrades.
For engineers reviewing the TIBPAL16R8-12MFKB datasheet, TIBPAL16R8-12MFKB pinout, TIBPAL16R8-12MFKB application, or TIBPAL16R8-12MFKB equivalent, this page provides verified functional identity, military-temperature timing specs, register preload behavior, OE-controlled 3-state output architecture, and direct alternatives for obsolescence mitigation in aerospace, defense, and industrial retrofits.
Technical Context
The TIBPAL16R8-12MFKB implements an IMPACT-X™ architecture with a 32 × 64 programmable AND array feeding eight D-type flip-flops, each with asynchronous preload and synchronous clocking. All eight outputs are registered and 3-state controllable via a common output enable (OE) signal.
It uses titanium-tungsten fuses for nonvolatile configuration, supports preloading registers to arbitrary states during test, and performs automatic low-level reset of all Q outputs at power-up-though physical pin voltages rise high due to internal pull-ups-enabling reliable state-machine bootstrapping in safety-critical systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Type | Registered PAL with 8 D-flip-flops and 3-state outputs |
| Max Clock Frequency (no feedback) | 56 MHz minimum - defines upper limit for combinational-to-registered path timing |
| Propagation Delay (CLK→Q) | 10 ns maximum - determines minimum clock period for synchronous register updates |
| Operating Temperature Range | −55°C to 125°C - qualified for full military environmental stress screening |
| Supply Voltage Range | 4.5 V to 5.5 V - supports stable operation across wide input rail variation in ruggedized systems |
| Output Drive (IOL / IOH) | 12 mA sink / −2 mA source - sufficient for direct TTL loading without buffers in legacy backplanes |
| Input/Output Count | 8 dedicated inputs, 0 I/O bidirectional pins, 8 registered outputs - fixed I/O partitioning per PAL16R8 architecture |
Pinout & Package
Package: 20-pin ceramic flatpack (FK), hermetically sealed for high-reliability military applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK | Single global clock input synchronizing all eight registers |
| 2–9 | I | Eight dedicated asynchronous inputs to the programmable AND array |
| 10 | GND | Power ground reference for all internal logic and output drivers |
| 11 | VCC | +5 V supply pin - must be decoupled locally for noise immunity |
| 12–19 | Q | Eight registered, 3-state outputs - driven only when OE is active low |
| 20 | OE | Active-low output enable controlling 3-state behavior of all Q pins |
Key Features
| Feature | Design Value |
|---|---|
| Preload Capability | Each register can be asynchronously loaded to high or low prior to test execution - eliminates need for exhaustive state traversal during production test |
| Power-Up Clear | All Q outputs reset to logic low at power-on - ensures known initial state without external reset circuitry |
| Military Temperature Rating | −55°C to 125°C operation - validated for deployment in avionics, missile guidance, and ground vehicle ECUs |
| Security Fuse | Hardware fuse prevents unauthorized readback or duplication of programmed logic - critical for IP protection in defense contracts |
| IMPACT-X™ Technology | Advanced Low-Power Schottky process with titanium-tungsten fuses - delivers speed/power balance superior to standard TTL PLDs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar registered PAL applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMD PALCE16V8H-15JC | CMOS EEPROM-based, 15 ns speed grade, 5 V tolerant, no military temp option | Lacks −55°C to 125°C qualification; requires external VPP programming voltage | Preferred for commercial upgrades where reprogrammability outweighs environmental ruggedness |
| TI TIBPAL16R8-12CNB | Same logic function and timing, but in 20-pin plastic DIP (N package) instead of ceramic flatpack (FK) | Not qualified for military temperature range; lower moisture resistance and thermal conductivity | Acceptable for non-mission-critical industrial use where cost and solderability are prioritized over hermeticity |
Compared with AMD PALCE16V8H-15JC and TI TIBPAL16R8-12CNB, the TIBPAL16R8-12MFKB uniquely satisfies full MIL-PRF-38535 Class B requirements, offers hardware security fusing, and guarantees timing performance across the extended temperature range-making it irreplaceable in certified flight hardware and nuclear instrumentation systems.

FAQ
What is the operating temperature range of the TIBPAL16R8-12MFKB?
The TIBPAL16R8-12MFKB is fully characterized and qualified for operation from −55°C to 125°C, meeting MIL-STD-883 requirements for military and aerospace applications. This range is explicitly defined in the SRPS017D datasheet revision and confirmed by thermal testing across the ceramic FK package's hermetic construction.
Does the TIBPAL16R8-12MFKB support in-system programming?
No, the TIBPAL16R8-12MFKB uses one-time-programmable titanium-tungsten fuses and requires external UV-erasable or parallel programmers prior to mounting. It does not support in-system or field reprogramming - a deliberate design choice for security and reliability in certified hardware where logic integrity must be immutable after burn-in.
How does the power-up clear function behave on the TIBPAL16R8-12MFKB?
At power-up, all eight register outputs (Q1–Q8) of the TIBPAL16R8-12MFKB are forced to logic low internally. However, because outputs are 3-state and OE is high by default, the pins float high due to external pull-ups - a behavior documented in the "Power-Up Reset" section (Figure 2) of the SRPS017D datasheet.
What is the maximum clock frequency specification for TIBPAL16R8-12MFKB with feedback paths?
The TIBPAL16R8-12MFKB guarantees a minimum clock frequency of 48 MHz when feedback paths are used in the logic design. This value is measured under worst-case conditions (VCC = 4.5 V, TA = 125°C) and reflects the longest combinational path through the AND array plus register setup time.
Is the TIBPAL16R8-12MFKB pin-compatible with other PAL16R8 variants?
Yes - the TIBPAL16R8-12MFKB shares identical pinout and logic architecture with all TIBPAL16R8 derivatives (e.g., -10C, -12CNB), including CLK on Pin 1, OE on Pin 20, and Q outputs on Pins 12–19. Differences are limited to speed grade, temperature range, and package type - not pin assignment or functional mapping.
