74FCT octal buffer — 32 mA / 64 mA bus drive in a 20-SOIC wide-body
The Texas Instruments CY74FCT244DTSOC is a non-inverting octal buffer from the 74FCT logic family, packaged in a 20-SOIC wide-body (7.50 mm width) for surface-mount assembly. It integrates two independent 4-bit elements, each with 3-state outputs, delivering 32 mA source and 64 mA sink per output — the drive strength that distinguishes the FCT family from slower 74LS or 74HC alternatives. The active lifecycle status means no near-term obsolescence risk for production builds.
5 V supply, 64 mA sink — what the drive ratings mean for your bus
The 32 mA source / 64 mA sink capability is the headline selection parameter. The 3-state outputs let multiple buffers share a data bus.
