SN74LVC1T45DBVR

SN74LVC1T45DBVR is the tape-and-reel SOT-23-6 ordering code for the Texas Instruments SN74LVC1T45 single-bit dual-supply bus transceiver, listed as Active in the datasheet package option addendum. Its verified figures: two supply rails, VCCA and VCCB, each from 1.65 V to 5.5 V in any relation to the other, data rates up to 420 Mbps, propagation delay of 3.9 ns, maximum supply current of 4 µA and output drive of ±24 mA at 3.3 V, over −40 °C to +85 °C, with a direction-control pin setting the transfer direction. The selection point is one-bit level translation with direction control in six pins: the standard fix for a single control or data line crossing between 1.8 V, 2.5 V, 3.3 V and 5 V domains without a bus-wide translator package. Selection advice: this is a directed transceiver, not an auto-sensing one — if your line must change direction without a control signal (an open-drain bus, for example), choose an auto-direction family instead; if the direction is known, the 1T45 is the smaller and faster answer. Parameters verified against the TI SN74LVC1T45 datasheet (package option addendum) and the TI product page.
