SN74LVC8T245PWR

SN74LVC8T245PWR is the tape-and-reel TSSOP-24 ordering code for the Texas Instruments SN74LVC8T245, an 8-bit dual-supply bus transceiver with configurable voltage translation, listed as ACTIVE. Each port runs from its own supply — VCCA and VCCB each accept 1.65 V to 5.5 V — so one package bridges a 1.8 V processor bus to a 3.3 V or 5 V peripheral bank without a separate level-shifter stage. Verified figures: a supply current of 8 µA maximum per side and input current held to ±2 µA maximum, across −40 °C to +85 °C. The selection point is byte-wide translation with direction and output-enable control in a single reel-ready logic code. Selection advice: this is the dual-supply translator. The single-supply SN74LVC245A also supports the maker-listed down-translation cases, but its ports share one VCC rather than independent supply rails. Other voltage-domain combinations require input-threshold and loaded-output checks; it is not a general-purpose substitute for this dual-supply translator — so confirm both rails against the 8T245 code before substituting either way. Parameters verified against the TI SN74LVC8T245 datasheet and product page.
