74F245SC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74F245SC is an octal bidirectional transceiver with 3-STATE outputs, manufactured using Fairchild's FAST (Fast Advanced Schottky Transistor Logic) technology. It operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of 0°C to +70°C. The device features non-inverting buffers with asymmetric current sinking capabilities: Side A ports sink up to 24mA, while Side B ports sink up to 64mA. Propagation delay ranges from 2.0ns to 7.5ns depending on operating conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Asymmetric output drive strength allows Side B ports to sink significantly higher current than Side A ports for bus driving applications.
• Directional data flow is controlled by the Transmit/Receive input, enabling flexible bidirectional communication paths.
• Outputs enter a high-impedance state when the Output Enable input is HIGH, isolating the device from the bus.

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and instrument control systems
• High-speed data transmission between logic circuits
• Parallel data transfer in industrial automation equipment

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the datasheet ordering information, as the 'SC' suffix denotes the 20-Lead Small Outline Integrated Circuit (SOIC). Confirm that the application environment remains within the recommended operating temperature limits of 0°C to +70°C. Ensure power supply voltages do not exceed the absolute maximum ratings to prevent device damage.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when asymmetric drive strength is required, specifically utilizing the high-current capability of the Side B ports. Compare propagation delays against system timing requirements, noting variations across temperature ranges. Consider the SOIC package dimensions for PCB layout constraints relative to other available packages like SOP or SSOP.
