Product Overview
TXB0108PWR is an 8-bit noninverting bidirectional voltage-level translator from Texas Instruments for Signal_Chain designs that need translation between lower-voltage and higher-voltage logic domains. The device uses auto-direction sensing for bidirectional voltage-level translation, so no separate direction-control input is specified in the extracted facts.
The A-port supply operates from 1.2 V to 3.6 V, while the B-port supply operates from 1.65 V to 5.5 V. Recommended operation requires VCCA to be less than or equal to VCCB. Data input thresholds are defined as 0.65 x VCCI for high level and 0 to 0.35 x VCCI for low level, where VCCI is the input port supply voltage.
The device is supplied in the PW, TSSOP-20 package with a 6.50 mm x 4.40 mm nominal body. OE is referenced to VCCA; pulling OE low places all outputs in the high-impedance state. Operating free-air temperature is -40 to 85 °C, with storage temperature from -65 to 150 °C and junction temperature rated to 150 °C.
