At 3.3V the 24 mA drive gives clean edges on short stubs; at 1.8V the drive current is lower but still adequate for point-to-point links under a few inches. If your bus has more than a handful of loads, budget a derating check at the lower supply corner. Housed in a 24-TSSOP package with a 4.40mm body width (0.173\"), it fits a standard 0.65mm-pitch TSSOP-24 footprint. The 3-state outputs let you share the bus with other transceivers or a microcontroller without contention; the output-enable control (not detailed here) is typically active-low per the 74LVC convention. For new designs, there is no LTB risk; the part is available through the standard TI distribution channel and independent supply.","metaTitle":"SN74LVC646APW 74LVC 8-bit Transceiver, 1.65V–3.6V, 24-TSSOP","metaDescription":"Texas Instruments SN74LVC646APW 8-bit non-inverting transceiver with 3-state outputs.
