PLUS16R8D

www.DataSheet4U.com Philips Semiconductors Programmable Logic Devices Product specification PAL devices 16L8, 16R8, 16R6, 16R4 PLUS16R8D/-7 SERIES FEATURES Ultra high-speed – tPD = 7.5ns and fMAX = 74MHz for the PLUS16R8-7 Series – tPD = 10ns and fMAX = 60 MHz for the PLUS16R8D Series DESCRIPTION The Philips Semiconductors PLUS16XX family consists of ultra high-speed 7.5ns and 10ns versions of Series 20 PAL devices. The PLUS16XX family is 100% functional and pin-compatible with the 16L8, 16R8, 16R6, and 16R4 Series devices. The sum of products (AND-OR) architecture is comprised of 64 programmable AND gates and 8 fixed OR gates. Multiple bidirectional pins provide variable input/output pin ratios. Individual 3-State control of all outputs and registers with feedback (R8, R6, R4) is also provided. Proprietary designs can be protected by programming the security fuse. The PLUS16R8, R6, and R4 have D-type flip-flops which are loaded on the Low-to-High transition of the clock input. In order to facilitate state machine design and testing, a power-up reset function has been incorporated into these devices to reset all internal registers to Active-Low after a specific period of time. The Philips Semiconductors State-of-the-Art oxide isolation Bipolar fabrication process is employed to achieve high-performance operation. The PLUS16XX family of devices are field programmable, enabling the user to quickly generate custom patterns using standard programming equipment. See the ...
