SN74LVC4245APWR

SN74LVC4245APWR is the tape-and-reel TSSOP-24 ordering code for the Texas Instruments SN74LVC4245A dual-supply octal bus transceiver, listed as ACTIVE on the TI part-details page for this code. Its verified figures: a 5 V-side supply (VCCA) of 4.5 V to 5.5 V and a low-voltage side (VCCB) of 2.7 V to 3.6 V, maximum data rate of 200 Mbps, propagation delay of 6.7 ns and maximum supply current of 0.13 mA, over −40 °C to +85 °C. The selection point is byte-wide 5 V to 3.3 V translation with three-state outputs and a direction pin: the bridge for a legacy 5 V bus meeting a 3.3 V processor, without eight single-gate translators or a level-shifting redesign of the backplane. Selection advice: the two rails are not interchangeable — the A side is specified only at 5 V-class voltages, so a design needing 3.3 V to 2.5 V translation belongs to a different member of the LVC translator family; confirm both rail voltages against the code before layout. Parameters verified against the TI SN74LVC4245A product page (part-details for this code).
