Because it is a single-supply transceiver, both sides of the bus run at the same VCC; if you need asymmetric translation (e.g., 1.8V to 3.3V), pair it with a dedicated level-shifting device. The 24 mA output current at 3.3V is typical for 74LVC and drives standard CMOS or TTL loads with good noise margin. ## Package and board layout The 56-lead SSOP (BSSOP body width 0.295 inches, 7.50 mm) is a surface-mount package. ## Temperature grade and environment If the board sees sustained junction temperatures above 85°C, check the derating curves in the datasheet for output current versus temperature — the 24 mA drive is specified at 25°C and may need derating at the high end.","metaTitle":"SN74LVC16646ADL 16-bit bus transceiver, 1.65V–3.6V, 56-SSOP","metaDescription":"Texas Instruments SN74LVC16646ADL 16-bit non-inverting bus transceiver with 3-state outputs.
