SN74HCT244DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT244DWR is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74HCT logic family. It features two independent four-bit buffers with separate output enable inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and provides non-inverting data transfer from A inputs to Y outputs when enabled. It utilizes a 20-pin SOIC surface-mount package and supports tri-state outputs for bus driving applications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 20-SOIC package dimensions align with the target PCB footprint. Ensure the HCT logic family compatibility matches the existing system voltage and interface requirements before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring eight-channel signal buffering with high noise immunity provided by the HCT technology. It is suitable for applications needing low power consumption alongside standard CMOS performance. Consider the 20-pin SOIC form factor for space-constrained surface-mount designs requiring robust drive capability for multiple loads.
