Part # 74LS280 datasheet

Part Manufacturer: Motorola


Part Description: 74LS280

Part Details:

SN54/74LS280 9-BIT ODD/EVEN PARITYGENERATORS/CHECKERS The SN54 / 74LS280 is a Universal 9-Bit Parity Generator / Checker. It fea- tures odd / even outputs to facilitate either odd or even parity. By cascading,the word length is easily expanded. 9-BIT ODD / EVEN PARITY The LS280 is designed without the expander input implementation, but the GENERATORS / CHECKERS corresponding function is provided by an input at Pin 4 and the absence of anyconnection at Pin 3. This design permits the LS280 to be substituted for the LOW POWER SCHOTTKY LS180 which results in improved performance. The LS280 has bufferedinputs to lower the drive requirements to one LS unit load. · Generates Either Odd or Even Parity for Nine Data Lines · Typical Data-to-Output Delay of only 33 ns · Cascadable for n-Bits J SUFFIX · Can Be Used To Upgrade Systems Using MSI Parity Circuits CERAMIC · CASE 632-08 Typical Power Dissipation = 80 mW 14 1 INPUTS VCC F E D C B A N SUFFIX 14 13 12 11 10 9 8 PLASTIC CASE 646-06 14 F E D C B 1 G A H I EVEN ODD D SUFFIX SOIC
