Product details
Overview
TIBPAL16R8-30MWB from Texas Instruments is a military-grade, registered 8-output programmable array logic (PAL) device with 8 dedicated inputs, 8 registered 3-state outputs, and a maximum propagation delay of 30 ns. It operates across −55°C to 125°C, features power-up clear (all registers set high), and supports preload for state-machine testing in avionics and defense control systems.
For engineers reviewing the TIBPAL16R8-30MWB datasheet, TIBPAL16R8-30MWB pinout, TIBPAL16R8-30MWB application, or TIBPAL16R8-30MWB equivalent, key selection criteria include its CFP-20 ceramic flatpack package, 25 MHz max clock frequency, OE-controlled 3-state output drive, and compatibility with legacy TTL-level system buses requiring deterministic register initialization.
Technical Context
This device implements a fixed-architecture PAL with an 8-input AND-OR logic array feeding eight D-type flip-flops, each with individual output enable (OE) control. All registered outputs are synchronized to a single CLK input and support preloading via dedicated VIHH voltage on Pin 11.
Its logic structure provides combinational fan-in to registered outputs without internal feedback paths, and power-up reset ensures all Q outputs initialize to logic high-critical for fail-safe state-machine boot sequences in ruggedized embedded controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 30 ns max - guarantees timing closure in 25 MHz synchronous designs with margin |
| Max Clock Frequency | 25 MHz - defines upper limit for state-transition rate in sequential logic applications |
| Operating Temperature | −55°C to 125°C - qualified for extended-range military and aerospace environments |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V TTL bus systems with ±10% tolerance |
| Output Drive | IOL = 12 mA / IOH = −2 mA - sufficient to directly drive multiple TTL loads without buffers |
| Package Type | CFP-20 (Ceramic Flatpack) - hermetic, high-reliability packaging for harsh thermal and vibration conditions |
| Logic Architecture | 8-input × 8-output registered PAL - fixed macrocell count with no I/O feedback routing |
Pinout & Package
Package: CFP-20 (Ceramic Flatpack), 20-pin, hermetically sealed, lead finish SNPB, non-RoHS compliant, MSL rating N/A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK | Positive-edge-triggered clock input for all eight registers |
| 2–9 | I | Dedicated logic inputs (8 total); no feedback capability |
| 10 | GND | Ground reference for logic and power domains |
| 11 | OE | Active-low output enable controlling all eight registered outputs |
| 12–19 | Q | Registered 3-state outputs (8 total); high-impedance when OE = high |
| 20 | VCC | +5 V supply pin; decoupling required per MIL-STD-883 |
Key Features
| Feature | Design Value |
|---|---|
| Power-Up Clear | All Q outputs initialize to logic high at VCC ramp completion-eliminates external reset sequencing in safety-critical boot paths |
| Preload Capability | Individual register preload via VIHH (10.25–10.75 V) on Pin 11 enables deterministic test-state injection without clock cycling |
| Military Temperature Range | −55°C to 125°C operation verified per MIL-PRF-38535 - suitable for engine bay, radar, and satellite subsystems |
| Hermetic CFP Packaging | Ceramic flatpack construction prevents moisture ingress and ensures long-term reliability under thermal shock and high-humidity conditions |
| TTL-Compatible I/O | VIH = 2 V min / VIL = 0.8 V max - interoperable with legacy 5 V TTL families without level-shifting |
Applications
| Avionics Flight Control Logic | Missile Guidance Interface |

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 | Same CFP-20 package, identical pinout, and MIL-PRF-38535 Class B qualification; identical 30 ns tpd and −55°C to 125°C range | No functional difference; differs only in part numbering convention and procurement channel (JAN vs TI branded) | Select when sourcing through U.S. DoD-approved distributors requiring JAN prefix compliance |
| TIBPAL16R8-30MJB | Same logic function and timing, but in CDIP-20 plastic package; lower thermal performance and non-hermetic construction | Not suitable for high-vibration or high-humidity environments; limited to benign industrial or lab use | Choose only for cost-sensitive prototyping where military environmental specs are not required |
Compared with JM38510/50606BRA and TIBPAL16R8-30MJB, the TIBPAL16R8-30MWB offers identical functionality and military-grade reliability in a ceramic flatpack, making it the preferred choice for flight-critical and space-qualified deployments where hermeticity and thermal stability are non-negotiable.

FAQ
What is the maximum clock frequency supported by the TIBPAL16R8-30MWB?
The TIBPAL16R8-30MWB supports a maximum clock frequency of 25 MHz under recommended operating conditions (VCC = 4.5 V to 5.5 V, TA = −55°C to 125°C). This limit is derived from its 30 ns maximum propagation delay and minimum pulse width requirements (15 ns high, 20 ns low), ensuring reliable register sampling across the full military temperature range.
Does the TIBPAL16R8-30MWB require external reset circuitry?
No, the TIBPAL16R8-30MWB includes built-in power-up clear: all registered outputs (Q) are set high upon VCC ramp completion, provided the rise is monotonic. This eliminates need for external reset generators in systems where default-safe output states are required at power-on.
Can the TIBPAL16R8-30MWB be used as a drop-in replacement for PAL16R8A?
Yes-the TIBPAL16R8-30MWB is functionally equivalent and faster than PAL16R8A, with identical pinout and logic architecture. However, it is not a direct drop-in for commercial applications due to its military temperature range and CFP packaging; board layout changes may be needed for thermal and mechanical integration.
What programming equipment is required for the TIBPAL16R8-30MWB?
The TIBPAL16R8-30MWB uses titanium-tungsten fuses and is programmed using industry-standard PAL programmers supporting 5 V TTL-level programming algorithms. Texas Instruments provides complete programming specifications and firmware upon request; no special high-voltage programming supply is required beyond standard 5 V and VIHH (10.5 V) for preload.
Is the TIBPAL16R8-30MWB RoHS compliant?
No-the TIBPAL16R8-30MWB uses SNPB (tin-lead) lead finish and is not RoHS compliant. It is manufactured per MIL-PRF-38535 Class B requirements and intended for applications where hermetic packaging and legacy solder compatibility outweigh RoHS mandates.
