SN74AXC8T245PWR

SN74AXC8T245PWR is an 8-bit dual-supply voltage level translator with direction control, in a 24-pin TSSOP (PW) tape-and-reel code. The selection point is the AXC supply envelope: both the A-side and B-side rails accept 0.65 V to 3.6 V, so the device bridges the newest sub-1 V SoC and FPGA I/O domains to established 1.8 V, 2.5 V and 3.3 V peripherals, in either direction, at data rates up to 380 Mbps. The eight channels are organised as two 4-bit banks with independent direction pins, letting one package serve, for example, a transmit nibble and a receive nibble with opposite data flow. Glitch-free power sequencing and Ioff protection keep partially powered systems from back-driving rails during hot-plug and staged start-up, a common failure in modular compute and communications blades. Selection advice: for a full byte-wide bus that changes direction as a unit, this 245-style control scheme is simpler than auto-direction parts, which can misbehave with pull-ups or heavily loaded lines. Fix both rail voltages in the design review before ordering support components, because the wide 0.65 V floor is the reason to pay for AXC over the older AVC family.
