TXS0108ERKSR in TXS0108 / BSS138 Level Shifters Family
The TXS0108ERKSR family by Texas Instruments consists of 8-bit bidirectional voltage-level translators designed for mixed-voltage digital systems. These components facilitate seamless communication between devices operating at different supply rails, ranging from 1.2V to 3.6V on the A-port and 1.65V to 5.5V on the B-port. Utilizing an auto-direction sensing architecture with integrated pull-up resistors, these translators eliminate the need for a direction-control signal, making them ideal for interfacing legacy peripherals with modern low-voltage microcontrollers.
Variants within the TXS0108 sub-family differ primarily in package type, temperature rating, and ESD protection levels. While the ERKSR denotes a specific VQFN-20 footprint, other versions utilize TSSOP or UQFN packaging. Some automotive-grade variants are AEC-Q100 qualified, offering enhanced thermal stability and reliability for harsh environments. Performance specifications remain consistent across the series, though parasitic capacitance varies slightly depending on the physical package and lead geometry.
