SN74BCT244DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT244DW is an octal buffer and line driver manufactured by Texas Instruments, belonging to the BCT logic family. It features eight non-inverting channels with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides high drive capability with maximum output currents of -80 mA for high state and 188 mA for low state. Propagation delay is specified at 5.6 ns under a 50 pF load at 5 V. The component supports surface mount installation and functions across a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Ensure the order matches the required operating temperature range and electrical characteristics. Confirm RoHS compliance status as per the latest product change notifications. Cross-reference the ordering part number with official distributor catalogs to avoid substitution errors during procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high current drive capability is required for long traces or multiple loads. The BCT series offers faster switching speeds compared to standard HC logic while maintaining CMOS input compatibility. Consider the thermal performance of the SOIC-20 package for high-density PCB layouts. Verify that the system voltage remains within the 4.5 V to 5.5 V operational window for reliable performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the SN74BCT family, designed for high-speed applications requiring strong drive strength. It serves as a direct replacement for similar octal buffers in legacy designs. The BCT technology combines the speed of bipolar circuits with the low power consumption of CMOS inputs. It is widely used in telecommunications and computing equipment where signal integrity is critical.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74BCT244DWR is the reel version of the same device. SN74ACT244DW offers similar functionality but with ACT logic characteristics. SN74HCT244DW provides HCT input compatibility instead of ACT/BCT levels.
