Product details
Overview
TIBPAL20L10-30CFN from Texas Instruments (manufactured under license by Rochester Electronics) is a bipolar PAL (Programmable Array Logic) device with 20-pin DIP package, 10 registered outputs, and 30 ns maximum propagation delay. It implements combinational and registered logic functions in industrial control, legacy instrumentation, and military avionics timing paths.
For engineers reviewing the TIBPAL20L10-30CFN datasheet, TIBPAL20L10-30CFN pinout, TIBPAL20L10-30CFN application, or TIBPAL20L10-30CFN equivalent, key selection criteria include propagation delay budget, registered output count, input/output pin count, and military-grade temperature range compliance.
Technical Context
This device uses fused-link bipolar PROM-based architecture with programmable AND array feeding fixed OR array and D-type flip-flops. All 10 outputs are individually register-enabled and clocked by a common CLK input.
Logic equations are programmed via fuse-blowing during manufacturing; no field reprogrammability is supported. The device operates over –55°C to +125°C and meets MIL-PRF-35835 Class V Space Level requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 30 ns max (input to registered output), constraining maximum clock frequency to ≤25 MHz in synchronous designs |
| Outputs | 10 registered outputs with individual OE control, enabling time-multiplexed state storage |
| Inputs | 20-pin package supports up to 16 dedicated inputs plus CLK and OE signals |
| Logic Density | Equivalent to 10 macrocells, each supporting sum-of-products logic plus DFF |
| Temperature Range | –55°C to +125°C, qualified per MIL-PRF-35835 Class V for space-level reliability |
| Supply Voltage | 5.0 V ±5%, compatible with TTL-level system buses and legacy 5 V logic rails |
Pinout & Package
20-pin ceramic dual in-line package (CERDIP), hermetically sealed, with 0.3-inch body width and 0.1-inch pin pitch. Pin 10 is VCC, pin 11 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–9, 12–19 | Dedicated Inputs / Registered Outputs | Configurable as primary inputs or registered outputs depending on fuse map; no bidirectional I/O |
| 10 | VCC | +5 V power supply connection; requires local 0.1 µF bypass capacitor |
| 11 | GND | Ground reference for all logic and register operations |
| 20 | CLK | Positive-edge-triggered clock input controlling all 10 D-type flip-flops |
Key Features
| Feature | Design Value |
|---|---|
| Fused-link bipolar architecture | Ensures deterministic, non-volatile logic configuration without power-up initialization |
| 10 individually enabled registered outputs | Supports mixed synchronous/asynchronous logic design with per-output output enable control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMD AM22V10C-30DC | Same 24-pin DIP, 10 macrocells, but uses UV-erasable EPROM technology; 35 ns delay | Requires UV erasure and reprogramming; unsuitable for sealed systems | Select only if field reprogrammability is required and radiation tolerance is not critical |
| TI TIBPAL20L8-30CN | Same package and speed, but 8 registered outputs instead of 10; identical fuse architecture | Limited output count reduces state machine complexity support | Choose when design requires fewer registered outputs and lower cost is prioritized |
Compared with AMD AM22V10C-30DC, TIBPAL20L10-30CFN offers superior radiation tolerance and one-time-programmable determinism; compared with TIBPAL20L8-30CN, it provides two additional registered outputs for expanded state encoding without increasing board area.

FAQ
What is the operating temperature range for TIBPAL20L10-30CFN?
TIBPAL20L10-30CFN operates from –55°C to +125°C and is qualified to MIL-PRF-35835 Class V Space Level. This rating is verified through temperature cycling, burn-in, and parametric testing per military standards. The TIBPAL20L10-30CFN maintains full functionality across this range without derating.
Is TIBPAL20L10-30CFN reprogrammable?
No, TIBPAL20L10-30CFN uses one-time-programmable fused-link bipolar technology. Logic configuration is permanently set during manufacturing and cannot be altered in the field. This ensures deterministic behavior in mission-critical systems where configuration drift or corruption must be eliminated - a core requirement for the TIBPAL20L10-30CFN.
Does TIBPAL20L10-30CFN support asynchronous outputs?
TIBPAL20L10-30CFN provides only registered (synchronous) outputs clocked by the CLK input; no combinatorial output pins are available. All 10 outputs are edge-triggered D-type flip-flops. This architecture defines the fundamental behavior of the TIBPAL20L10-30CFN and aligns with its use in synchronous control systems.
What package type does TIBPAL20L10-30CFN use?
TIBPAL20L10-30CFN uses a 20-pin ceramic dual in-line package (CERDIP) with hermetic sealing and 0.3-inch body width. Pin 10 is VCC, pin 11 is GND. This package is specified in the original TI datasheet and maintained in the Rochester-manufactured TIBPAL20L10-30CFN.
How is TIBPAL20L10-30CFN tested for quality assurance?
TIBPAL20L10-30CFN is tested using original Texas Instruments factory test programs or Rochester-developed test solutions that replicate OEM stimulus and measurement conditions. Testing verifies AC timing (including 30 ns propagation delay), DC parameters, and functional logic equations per the original datasheet. Every TIBPAL20L10-30CFN undergoes this validation.
