TXS0104EPWR

TXS0104EPWR is the tape-and-reel TSSOP-14 ordering code for the Texas Instruments TXS0104E four-bit bidirectional level translator, listed by TI as ACTIVE. The A-side supply runs from 1.65 V to 3.6 V and the B-side supply from 2.3 V to 5.5 V, with VCCA never above VCCB; the maximum data rate is 24 Mbps with push-pull drivers and 2 Mbps with open-drain drivers, supply current is 25 µA maximum, the B port carries ±15 kV HBM ESD protection and IEC 61000-4-2 ratings of ±8 kV contact and ±10 kV air, and the PWR variant operates from -40 °C to +85 °C. The selection point is automatic direction sensing across four channels: I2C, SPI-adjacent control lines and mixed-voltage GPIO cross between 1.8 V, 2.5 V, 3.3 V and 5 V domains with no direction pin and no firmware involvement. Selection advice: the TXS architecture suits push-pull and open-drain buses at moderate edge rates - for high-capacitance or long-trace buses, check the edge-accelerator behaviour in the datasheet before committing, and keep VCCA at or below VCCB in the power sequencing. Parameters verified against the TI TXS0104E datasheet SCES686 and the TI part-details page for this variant.
