Operating from a 4.5V to 5.5V supply, it provides bidirectional data transfer with 3-State outputs for bus-oriented applications. With a robust output current capability of 32mA source and 64mA sink, it can drive heavily loaded buses and long transmission lines. The device is available in a compact 48-pin TFSOP package and operates over an industrial temperature range of -40°C to +85°C. Its fast propagation delays and low power consumption make it ideal for memory interfacing, backplane communication, and general-purpose data buffering in 5V digital systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh Output Drive (64mA Sink): Ensures signal integrity on long or heavily loaded buses, reducing the need for additional buffer ICs.\u003c\/li\u003e\n\u003cli\u003eIndustrial Temperature Range (-40°C to +85°C): Suitable for automotive and industrial environments where temperature extremes are common.\u003c\/li\u003e\n\u003cli\u003e3-State Outputs: Allows multiple devices to share a common data bus without contention, simplifying system design.\u003c\/li\u003e\n\u003cli\u003eFCT Logic Family Speed: Provides fast propagation delays (typically \u0026lt; 5ns), enabling high-frequency operation in performance-critical paths.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHigh-Density Bus Interfacing\u003c\/h3\u003e\u003cp\u003eIn systems with wide data buses (16-bit or more), the CD74FCT16245ATMT provides a single-chip solution for bidirectional communication.
