Features, Applications

High-Speed 8-Bit Parallel Pipeline Register Serial Shadow Register With Right-Shift Only 'ALS29818 Performs Parallel-to-Serial and Serial-to-Parallel Conversion Designed Specifically for Use in Applications Such As: Write Control Store ('ALS29818) Serial Shadow-Register Diagnostics 'ALS819 Provides Even-Parity Output Low Power Dissipation. 215 mW Typical 'ALS29818 is Functionally Equivalent to AMD AM29818 Package Options include Plastic Small Outline Packages, Standard Plastic DIPs, and Plastic Chip Carriers

description

The SN74ALS819 and SN74ALS29818 are 8-bit pipeline registers each with an on-chip shadow register. They are for use in applications such as write control store and shadow register diagnostics. The output registers of the 'ALS819 and 'ALS29818 are loaded in parallel from either the I/O port DQ7) or the shadow register. The shadow register of the 'ALS2981A 8 can be loaded serially or from either the I/O port Y7) or the pipeline register. The 'ALS819 shadow register can be loaded serially or from the I/O port DQ7). In addition, the 'ALS819 provides a Parity-Even (PE) output, which monitors parity of the output register. Operation of these devices is controlled by the Mode and SDI inputs as shown in the function table. The SN74ALS819 and SN74ALS29818 are characterized for operation from to 70C.
