The output drive is rated 32 mA source and 64 mA sink per channel — enough to drive a heavily loaded parallel bus or a bank of LED indicators without external buffers. ## Package reality: 56-pin SSOP, no field swap This is not a part you swap on site with a screwdriver — it needs a reflow station or hot-air rework. ## Lifecycle: still in current production","metaTitle":"SN74ABT16543DL 16-bit transceiver, 5 V, 56-SSOP, active","metaDescription":"Texas Instruments SN74ABT16543DL 16-bit non-inverting bus transceiver with 3-state outputs. 4.5 V to 5.5 V supply, -40°C to 85°C. 56-pin SSOP.
