- Address decoding logic
Procurement Notes
Verify the specific suffix 'DBR' corresponds to the SOIC-14 surface-mount package and tape-and-reel shipping configuration. Confirm RoHS compliance status and ensure the component meets the required industrial temperature specifications for the intended deployment environment before finalizing procurement orders.
Selection Notes
Select this component when designing 5 V logic systems requiring moderate speed and high drive current. It serves as a direct functional replacement for standard 74LS08 devices while offering superior noise immunity and faster switching speeds compared to legacy TTL families, making it suitable for modern digital interfaces.
Part Context
This part belongs to the Texas Instruments 74ACT series, which bridges the performance gap between older 74LS logic and faster CMOS technologies. The ACT family maintains pin compatibility with industry-standard TTL packages while utilizing advanced CMOS processes to deliver improved power efficiency and higher switching frequencies for general-purpose digital applications.
Replacement Considerations
Direct pin-compatible alternatives include the SN74ACT08DRG3 and SN74ACT08PWRQ1. Verify that substitute parts match the required package type and temperature rating.
