Texas Instruments 74AC | Texas Instruments
Texas Instruments 74AC advanced CMOS logic — SN74AC gates, buffers, and bus transceivers for 5V systems.
Texas Instruments 74AC Series Overview
Advanced CMOS logic family featuring very high speed and symmetric output drive.
The Texas Instruments 74AC family is advanced CMOS logic for 5V systems that need faster edges and stronger symmetric output drive than HCT or LS parts.
Common orderable devices include SN74AC04 inverters, SN74AC14 Schmitt-trigger inverters, SN74AC08 AND gates, and SN74AC245 octal bus transceivers. Compare those variants on this page, then open the matching product page for stock and RFQ.
Use 74AC when the design already runs on 5V CMOS levels and you need higher speed than 74HC. Check output current, package (SOIC, TSSOP, or PDIP), and temperature grade before freezing the BOM.
Octatronics lists 74AC / SN74AC orderables with package, lifecycle, and datasheet links so you can qualify a second source or replacement suffix without starting from a blank search.
