FINAL COM’L: -4/5/7/B/B-2/A, D/2 PAL16R8 Family 20-Pin TTL Programmable Array Logic DISTINCTIVE CHARACTERISTICS s As fast as 4.5 ns maximum propagation delay s Popular 20-pin architectures: 16L8, 16R8, 16R6, 16R4 s Programmable replacement for high-speed TTL logic s Register preload for testability s Power-up reset for initialization Advanced Micro Devices s Extensive third-party software and programmer support through FusionPLD partners s 20-Pin DIP and PLCC packages save space s 28-Pin PLCC-4 package provides ultra-clean high-speed signals GENERAL DESCRIPTION The PAL16R8 Family (PAL16L8, PAL16R8, PAL16R6, PAL16R4) includes the PAL16R8-5/4 Series which provides the highest speed in the 20-pin TTL PAL device family, making the series ideal for high-performance applications. The PAL16R8 Family is provided with standard 20-pin DIP and PLCC pinouts and a 28-pin PLCC pinout. The 28-pin PLCC pinout contains seven extra ground pins interleaved between the outputs to reduce noise and increase speed. www.DataSheet4U.com The AND array is programmed to create custom product terms, while the OR array sums selected terms at the outputs. In addition, the PAL device provides the following options: — Variable input/output pin ratio — Programmable three-state outputs — Registers with feedback Product terms with all connections opened assume the logical HIGH state; product terms connected to both true and complement of any single input assume the logical LOW state. Registers consist of ...
