Each element drives 15 mA high and 64 mA low — that 64 mA sink is the spec that decides the load: it handles TTL/CMOS fan-out to multiple downstream gates or a heavily loaded bus line without needing an external line driver. The 3-state outputs let you wire-OR multiple buffers onto the same bus — the high-Z state isolates the disabled element so the active one drives the line cleanly. ## Package and temperature — board-fit and environment This covers factory-floor enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics that see 70°C steady-state with 85°C peaks. No derating needed at the top end for this logic family. The part is RoHS non-compliant — the lead-bearing finish is intentional for high-reliability solder joints in industrial and aerospace assemblies where tin whisker risk is unacceptable.","metaTitle":"TI CY74FCT16827ETPAC Buffer Non-Inverting, 20-bit, 4.5-5.5V","metaDescription":"Texas Instruments CY74FCT16827ETPAC bus driver, 20-bit buffer with 3-state outputs, 15mA/64mA drive, -40 to 85°C, 56-TSSOP.

The CY74FCT16827ETPAC is a 20-bit buffer with 64 mA sink in a 56-pin TSSOP. Different pinout, different function — they are not drop-in replacements. The FCT series is a higher-drive, wider-bus family than the ABT transceiver."},{"question":"What does the 15mA/64mA output drive mean for my bus?","answer":"The 64 mA low-level sink current means this buffer can drive a heavily loaded backplane or a long trace with multiple receivers — each TTL input draws about 1.6 mA low, so 64 mA sinks roughly 40 standard loads. The 15 mA high-level source drives about 10 LSTTL loads. If your bus has more than that, you need a second buffer element or a bus transceiver."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CY74FCT16827ETPAC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CY74FCT16827ETPAC when reusing this data.
