It sits between two voltage domains — say a 1.8V microcontroller and a 3.3V peripheral — and passes data in either direction with the direction control per element. Each of the two elements handles four bits independently, so you get two separate bidirectional translation channels in one 16-SOIC package. The supply range spans 1.2V to 3.6V, which covers the common logic levels: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. Output drive is 12 mA source and 12 mA sink per channel — typical for the 74AVCH family and adequate for point-to-point board-level interconnect or lightly loaded buses. The 3-State outputs let you share a bus with other transceivers without contention. ## Temperature grade and where it fits Rated for -40°C to 85°C ambient, so it's a fit for industrial control panels, outdoor telecom cabinets, and automotive cabin electronics (non-engine-bay). The surface-mount 16-SOIC body is a standard footprint that reflows easily in a convection oven with no special handling beyond the usual MSL 3 bake check if the moisture-barrier bag has been open. ## Lifecycle and sourcing reality That means no last-time-buy math for a new design.","metaTitle":"TI SN74AVCH4T245D Translation Transceiver, 1.2V-3.6V","metaDescription":"TI SN74AVCH4T245D dual 4-bit translation transceiver. 1.2V to 3.6V supply, 12mA output, industrial temp.

That covers 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V logic levels — the common voltages you find bridging an MCU and a peripheral on the same board."},{"question":"Is SN74AVCH4T245D compatible with 3.3V and 1.8V?","answer":"Yes. Both 3.3V and 1.8V are within the 1.2V to 3.6V supply range. You can power one side at 3.3V and the other at 1.8V, and the part will translate signals between the two domains."},{"question":"Is SN74AVCH4T245D equivalent to SN74AVCH4T245?","answer":"The SN74AVCH4T245 is the base part number; the 'D' suffix indicates the 16-SOIC package. They are the same die in the same package — the 'D' is TI's package designator for SOIC.
