74ACTQ245SJX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ245SJX is an octal bidirectional transceiver utilizing ACTQ logic technology. It features eight non-inverting buffers with three-state outputs housed in a Pb-Free 20-Lead Small Outline Package (SOP). The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. It provides a current sinking capability of 24 mA at both ports A and B, ensuring robust drive strength for bus-oriented applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Utilizes FACT Quiet Series/G165 technology to guarantee quiet output switching and improved dynamic threshold performance.
• Features GTO output control and undershoot correction alongside a split ground bus for superior signal integrity.
• Provides guaranteed simultaneous switching noise levels and pin-to-pin skew AC performance.

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented data communication systems
• Driving bus lines or memory address registers
• Asynchronous two-way data transfer between buses

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package designation M20D corresponds to the required SOP form factor. Confirm that the Pb-Free status aligns with environmental compliance requirements. Ensure the ordering code includes the 'X' suffix if tape and reel packaging is necessary for the manufacturing process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed bidirectional data transfer is required with low noise characteristics. The ACTQ series offers faster propagation delays compared to standard ACT245 devices. Verify that the system power supply remains strictly within the 4.5V to 5.5V range to maintain electrical specifications.
