DESCRIPTION

The PLHS501 is a high-density Bipolar Programmable Macro Logic device. PML incorporates a programmable NAND structure. The NAND architecture is an efficient method for implementing any logic function. The SNAP software development system provides a user friendly environment for design entry. SNAP eliminates the need for a detailed understanding of the PLHS501 architecture and makes it transparent to the user. PLHS501 is also supported on the Philips Semiconductors SNAP software development systems.
