The symmetric 16mA output drive at both high and low levels is enough to drive a 74-series load or a short backplane trace; for longer runs or higher fan-out, plan on a buffer stage or a higher-drive variant like the 74LVTH family. ## Lifecycle and compliance For dual-sourcing resilience, the 74LVTH16245ADGVR offers a 2.7V to 3.6V supply and 32mA drive but operates only to 85°C — check the temperature grade if your environment exceeds that.","metaTitle":"SN74LV245APWR 74LV Transceiver, 8-bit, 2V-5.5V, 20-TSSOP","metaDescription":"Texas Instruments SN74LV245APWR 8-bit non-inverting transceiver with 3-state outputs. 2V to 5.5V supply, 16mA drive, -40°C to 125°C.
