The push-pull output eliminates the need for external pull-ups on the translated side. Bidirectional per channel — each of the two channels can independently translate in either direction without a direction-control pin. Single circuit, two channels per circuit — the 1:2 ratio means you get two independent translation paths in one package. ## Package and board-fit: 8-X1SON, 1.95 x 1 mm Housed in an 8-XFDFN Exposed Pad (supplier device package 8-X1SON, 1.95 x 1 mm). Surface-mount only — no through-hole variant. The 0.5 mm pitch and 0.4 mm pad width require standard SMT assembly; no special stencil aperture needed for the small package. ## Peer comparison: CAXC4T774QBQBRQ1 — automotive-grade, slower, 4-channel The closest functional peer is the CAXC4T774QBQBRQ1 (TI 74AXC family). It offers four bidirectional channels at 310 Mbps, AEC-Q100 qualified, with a lower minimum supply (0.65 V). The SN74LXC2T45DTTR trades channel count (2 vs 4) and automotive qualification for higher data rate (420 Mbps vs 310 Mbps) and a wider VCC range (1.1-5.5 V vs 0.65-3.6 V). Pinout is not compatible — the CAXC4T774 is a 14-pin package, while the SN74LXC2T45DTTR is 8-pin. No drop-in replacement without a board spin.","metaTitle":"TI SN74LXC2T45DTTR Voltage Level Translator, 420Mbps","metaDescription":"Texas Instruments SN74LXC2T45DTTR dual-bit bidirectional voltage-level translator, 420 Mbps, 1.1-5.5 V, 8-X1SON.
