G12491 - 74AS280 9-Bit Parity Generator/Checker

G12491 - 74AS280 9-Bit Parity Generator/Checker

item number: G12491
unit price:$1.10 

Detailed Description

These universal 9-bit parity generators/checkers utilize advanced Schottky high-performance circuitry and feature odd and even outputs to facilitate operation of either odd- or even-parity applications. The word-length capability is easily expanded by cascading.
These devices can be used to upgrade the performance of most systems utilizing the 74AS180 parity generators/checkers. Although the 74AS280 is implemented without expander inputs, the corresponding function is provided by the availability of an input (I) at terminal 4 and the absence of any internal connection at terminal 3. This permits the 74AS280 to be substituted for the 74AS180 in existing designs to produce an identical function even if the devices are mixed with existing 74AS180 devices. All 74AS280 inputs are buffered to lower the drive requirements. The 74AS280 is characterized for operation from 0°C to 70°C.
