Product details

The CY74FCT2244CTSOC is a 74FCT-series non-inverting buffer from Texas Instruments, organized as two independent 4-bit elements with 3-state outputs. It runs on a 4.75V to 5.25V supply rail — strictly 5V logic, not 3.3V compatible. Each output can source 15mA or sink 12mA, enough for standard TTL fan-out on a backplane or shared data bus. The 20-SOIC package (7.50mm wide body) is a common footprint for board-level buffering in industrial control, telecom line cards, and test equipment that still runs a 5V rail.

Temperature grade and deployment

The commercial-grade SN74LS645-1N (0°C to 70°C) would not survive those environments.

Frequently asked questions

Is CY74FCT2244CTSOC 3.3V compatible?

No. The minimum supply voltage is 4.75V. For a 3.3V bus buffer, look at the SN74LVTH16245ADGVR family which operates down to 2.7V.
