PAL16R8BCN

Programmable Logic Device Pld Overview

The PAL16R8BCN is a Programmable Array Logic (PAL) device from the PAL16R8 family, manufactured by Vantis. It features an architecture with 16 input lines and 8 registered output lines, providing 64 product terms for logic implementation. The component operates at a maximum clock frequency of 25 MHz with a typical propagation delay of 25 ns. It utilizes a 20-pin Plastic Quad Flatpack (PQFP) or similar plastic package variant depending on specific suffix interpretation, though standard PAL16R8 variants often use DIP or PLCC; the 'B' suffix typically denotes a faster speed grade within the series. The device supports TTL voltage levels and includes power-up reset functionality.

Programmable Logic Device Pld Part Context

The PAL16R8BCN belongs to the PAL16R8 family, which also includes variants like PAL16R8-5/4. This family is designed as a high-performance alternative to discrete TTL logic gates. The 'B' suffix generally indicates a specific speed bin or package variation within the Vantis/AMD lineage of PAL devices, offering improved timing characteristics over standard speed grades.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements include other PAL16R8 variants such as PAL16R8-5CNL or PAL16R8ACNL, provided the speed grade meets the design requirements. Ensure the replacement device supports the registered output configuration and compatible package type.
