SN74HCT244DWG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT244DWG4 is an octal buffer and line driver manufactured by Texas Instruments, belonging to the HCT logic series. It features eight non-inverting channels with three-state outputs housed in a 20-SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a maximum static current of 8 uA and a typical propagation delay of 45 ns at 4.5 V. Output drive capabilities are specified as -6 mA for high level and 6 mA for low level. The component supports surface mount installation and functions reliably across an operating temperature range from -40 C to +85 C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green manufacturing options when sourcing. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the 4.5V to 5.5V supply voltage aligns with your system design. Check for any recent production change notices that might affect pinout or material composition. Validate that the non-inverting logic function meets your circuit signal path needs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between different logic families requiring TTL-compatible input thresholds. The HCT series offers a balance of speed and power efficiency for standard digital applications. Consider the 20-pin SOIC package for space-constrained surface mount designs. Evaluate the three-state capability if bidirectional bus sharing is required in the architecture.
