PAL16R4-7/2PC Datasheet PDF - AMD

●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.

●The devices provide user-programmable logic for replacing conventional SSI/MSI gates and flip-flops at a reduced chip count.

●DISTINCTIVE CHARACTERISTICS
