Description and Introduction

LOW-POWER HIGH-PERFORMANCE IMPACT E PAL CIRCUITS The TIBPAL16R4-25C is a programmable array logic (PAL) device manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Texas Instruments (TI)  

### **Specifications:**  
- **Device Type:** Programmable Array Logic (PAL)  
- **Speed Grade:** 25 ns maximum propagation delay  
- **Operating Voltage:** 5V (standard TTL levels)  
- **Operating Temperature Range:** 0°C to 75°C (commercial grade)  
- **Package Type:** 20-pin ceramic DIP (Dual In-line Package)  
- **Number of Inputs:** 16  
- **Number of Outputs:** 4 (registered)  
- **Programmable AND Array:** Fixed OR array  
- **Technology:** Bipolar (TTL-compatible)  

### **Descriptions:**  
- The TIBPAL16R4-25C is a high-speed, low-power PAL device designed for implementing complex combinational and sequential logic functions.  
- It features a programmable AND array and a fixed OR array, allowing users to define custom logic operations.  
- The device includes registered outputs (flip-flops) for sequential logic applications.  

### **Features:**  
- **High-Speed Operation:** 25 ns maximum propagation delay.  
- **Registered Outputs:** Four outputs with D-type flip-flops for sequential logic.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard TTL logic levels.  
- **Electrically Programmable:** One-time programmable (OTP) using a PAL programmer.  
- **Wide Operating Temperature Range:** Suitable for commercial applications.  

This information is strictly based on the device's datasheet and manufacturer-provided details.

Application Scenarios & Design Considerations

LOW-POWER HIGH-PERFORMANCE IMPACT E PAL CIRCUITS

Alternative Part Number

  • PAL16R4ACN --: Same 16R4 PAL architecture with 25 ns class speed, pin-compatible DIP package, and widely available as a direct functional replacement.
  • PAL16R4AMD --: Standard 16R4 programmable array logic device with comparable propagation delay and identical 20-pin DIP pinout, suitable for direct substitution.
  • GAL16V8D-25LP --: Electrically erasable GAL that can emulate the 16R4 PAL function, offers 25 ns speed grade, and is a common modern replacement for obsolete PAL parts.
