It integrates two 8-bit elements, each with its own direction and output-enable controls, so a single device handles a full 16-bit data path without external muxing. The 4.5V to 5.5V supply range keeps it compatible with legacy 5V logic families and mixed-voltage backplanes. Output drive is rated at 32 mA sourcing and 64 mA sinking, enough to drive a heavily loaded parallel bus or a bank of LED indicators without external buffers. The industrial temperature range (-40°C to 85°C) suits it for factory-floor controllers, telecom line cards, and outdoor equipment where the ambient can swing. ## Package and mounting — 56-TSSOP footprint Housed in a 56-lead TFSOP (0.240\", 6.10 mm width) package, the CY74FCT162646CTPAC is a surface-mount device. The supplier device package is 56-TSSOP. ## Supply voltage and 5V tolerance The supply voltage range is 4.5V to 5.5V, which means the part is fully 5V-tolerant on the supply rail. Inputs are 5V-logic compatible across the range. This is a straight 5V device — no 3.3V operation, no dual-rail trick. If your design runs a 3.3V core and a 5V peripheral bus, this transceiver sits on the 5V side and level-shifting happens at the boundary. The 5.5V absolute maximum on the supply means a regulated 5V rail with ±10% tolerance stays inside the window; a 5V rail that drifts to 5.6V is already out of spec. ## Output drive — 32 mA / 64 mA Output drive is 32 mA sourcing (IOH) and 64 mA sinking (IOL). ## Lifecycle and compliance The CY74FCT162646CTPAC is listed as Active in production status. The RoHS status is marked as non-compliant.","metaTitle":"CY74FCT162646CTPAC 16-bit Transceiver, 5V Supply, 56-TSSOP","metaDescription":"CY74FCT162646CTPAC 16-bit non-inverting transceiver with 3-state outputs. 4.5V-5.5V supply, 32mA/64mA drive, -40°C to 85°C.
