The SN74ABT534DWR: It functions as a bus driver, latching data on the rising edge of the clock and presenting the inverted data on the outputs when the output-enable pin is low.
This part is RoHS non-compliant per. For RoHS-exempt builds (e.g., aerospace, military), this is acceptable.
For automated assembly, request a tape-and-reel variant.
The SN74ABT534 has inverted outputs — the data on the outputs is the logical inverse of the data latched at the input. The SN74ABT574 is a non-inverting version; its outputs follow the latched data directly. Both are 8-bit D-type flip-flops with three-state outputs, same pinout (except the output polarity), same ABT series speed and drive capability. Choose the 534 when the bus needs an inversion stage; choose the 574 for a straight-through buffer.
The 74ACT16833DL is a functional peer — it is a 16-bit bus driver with inverted outputs from the ACT family, but it is a different package (48-pin SSOP) and logic family (ACT vs ABT). The SNJ54ALS574AFK and SNJ95161BFK are military-grade parts in different logic families and packages; they are not drop-in replacements. For a direct ABT-series replacement with the same function and footprint, look at the SN74ABT534DW (same SOIC-20, non-RoHS) or the lead-free SN74ABT534DWRG4.
