74ABT244CSC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT244CSC is an octal buffer and line driver with 3-STATE outputs. It operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of -40°C to +85°C. The device features non-inverting buffers with output sink capability of 64 mA and source capability of 32 mA. Propagation delay is typically 2.5 ns at VCC = 5V with a 50 pF load. The component is housed in a 20-Lead Small Outline Integrated Circuit (SOIC) package, JEDEC MS-013, 0.300” Wide Body.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering code suffix against the manufacturer's current documentation to confirm package type and tape/reel availability. Confirm RoHS compliance status and lifecycle stage directly with the supplier or manufacturer before procurement. Ensure the requested part matches the exact SOIC M20B package specification required for the design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed data buffering with significant drive current is required. The ABT logic family offers faster propagation delays compared to standard HC or HCT families. Ensure the system operates strictly within the 4.5V to 5.5V supply voltage range to maintain electrical characteristics and avoid damage.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ABT logic family, which combines the speed of Advanced Bipolar Technology with CMOS low power consumption. It is functionally similar to other octal buffers like the 74ACT244 but optimized for higher drive currents and specific switching specifications under the ABT standard.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check datasheets for equivalent parts such as SN74ABT244 from Texas Instruments or MC74ABT244 from onsemi. Verify pin compatibility, package dimensions, and electrical parameters match the original design requirements.
