SN74BCT25244NT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT25244NT is an octal buffer and line driver from Texas Instruments, belonging to the BCT logic family. It features eight non-inverting channels with three-state outputs, organized into two groups of four bits each. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides high drive capability with a maximum low-level output current of 188 mA and a high-level output current of -80 mA. The propagation delay is specified at 5.6 ns at 5 V. It is housed in a 20-pin PDIP package and supports operation temperatures from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'N' corresponds to the PDIP-20 package variant when sourcing. Confirm the BCT series designation ensures compatibility with required drive strengths and voltage levels. Check datasheet revisions for any pinout or electrical characteristic updates before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high current drive on standard 5 V systems. The BCT technology offers improved performance over standard HC/HCT logic while maintaining TTL-compatible input thresholds. Ensure the PCB layout accommodates the thermal requirements associated with high sink currents during active switching periods.
