PAL16R4-10/BRA

Programmable Logic Device Pld Overview

The PAL16R4-10/BRA is a high-performance Programmable Array Logic (PAL) circuit manufactured by Advanced Micro Devices. It belongs to the PAL16R8 family, designed for high-speed TTL applications. The device features an 8-bit registered output architecture with 12 input lines and 4 dedicated I/O lines, totaling 8 outputs. Packaged in a 20-pin Ceramic Dual In-Line Package (CDIP), it supports an operating temperature range of -55°C to 125°C. The maximum clock frequency is rated at 40 MHz, with a typical propagation delay associated with the '10' speed grade.

Programmable Logic Device Pld Feature Summary

Programmable Logic Device Pld Part Context

This component is part of the PAL16R8 family, which includes variants like PAL16L8, PAL16R8, and PAL16R6. The PAL16R4 variant specifically provides registered outputs, distinguishing it from the combinatorial PAL16L8. The '/BRA' suffix typically denotes the ceramic package and specific temperature/quality grading within the AMD product line.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements may include other manufacturers' PAL16R4 devices, such as those from Texas Instruments or National Semiconductor. However, verification of electrical characteristics, particularly propagation delays and power consumption, is required when substituting across different foundries.
