CY74FCT257TQCT Description

Short technical summary and product information.

The CY74FCT257TQCT is a quad 2:1 multiplexer integrated circuit from Texas Instruments. It is designed for digital data routing and selection, offering four independent 2:1 multiplexer channels with 3-state outputs. The device operates from a single 4.75V to 5.25V supply, making it compatible with standard TTL logic levels. It features edge-rate control circuitry for improved noise characteristics and supports partial-power-down mode operation via Ioff protection. The multiplexer can sink up to 64 mA and source up to 32 mA, suitable for driving bus lines or capacitive loads. It is housed in a 16-pin SSOP package, ideal for space-constrained designs. The CY74FCT257TQCT is also pin-compatible with FCT and F logic families, simplifying upgrades in existing systems.
