Product details

The CY74FCT541ATSOCT is a single-element, 8-bit non-inverting buffer from the 74FCT logic family, with 3-state outputs. It operates from a 4.75 V to 5.25 V supply and is specified across -40°C to 85°C.

Output drive and bus interface

Rated output drive is 32 mA source and 64 mA sink per channel. The 3-state outputs let you disable the bus when another device drives it.

Housed in a 20-SOIC wide-body package (0.295" body width, 7.50 mm), the CY74FCT541ATSOCT uses a surface-mount footprint compatible with industry-standard SOIC-20 land patterns. The wide-body variant provides better thermal dissipation than the narrow SOIC for continuous high-drive operation.

Frequently asked questions

What is the exact replacement for CY74FCT541ATSOCT?

No direct replacement has been announced by the manufacturer. The part is still active, so no successor order code exists. For a functional equivalent, look for other 74FCT-series octal buffers in 20-SOIC with 3-state outputs and 5 V supply, such as the SN74ABT2245DW (transceiver variant) or SN74LVTH16245ADGVR (dual-supply transceiver), but verify pin compatibility and logic function for your specific application.
