Hot-selling and scarce PAL16R4ACN Programmable Logic Device (PLD) IC 4 Macrocells 20-PDIP spot stock

Product Descriptions

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 seriesideal 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.

The family allows the systems engineer to implement the design on-chip, by opening fuse links to configure AND and OR gates within the device, according to the desired logic function. Complex interconnections between gates, which previously required time-consuming layout, are lifted from the PC board and placed on silicon, where they can be easily modified during prototyping or production.
