74HCT244PW,112

Overview

The Nexperia 74HCT244PW,112 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level inputs. The device provides two independent output enable controls (1OE and 2OE), each managing four outputs. It supports ambient temperatures from -40 °C to +125 °C and is housed in a TSSOP20 package.

Feature Summary

• Octal bus interface with non-inverting three-state outputs
• TTL input levels for compatibility with standard logic families
• Dual output enables allowing flexible configuration as two 4-bit or one 8-bit buffer

Applications

• Bus-oriented transmissions
• Clock driving
• Buffering memory and data registers

Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and tape-and-reel specifications. Confirm that the component meets required environmental standards for the intended application before finalizing procurement decisions.

Selection Notes

Select this component when interfacing between TTL-compatible sources and high-impedance loads requiring isolation. Ensure the operating voltage remains within the specified 4.5 V to 5.5 V range to maintain correct logic thresholds and performance characteristics.

Part Context

This part belongs to the 74HCT series of hex/octal buffers. It shares functional similarities with other 3-state drivers but is distinguished by its specific HCT input levels and TSSOP20 packaging. It serves as a standard solution for digital signal buffering in mixed-voltage systems.

Replacement Considerations

Compatible substitutes include the 74HCT244D and 74HCT244BQ from Nexperia, provided the package footprint matches the design constraints.
