MC74AC244DTG

Overview

The MC74AC244DTG is an octal buffer and line driver from the onsemi AC logic series, housed in a 20-pin TSSOP surface-mount package. It features non-inverting polarity with three-state outputs and operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a maximum high-level output current of -24 mA and a low-level output current of 24 mA. The device exhibits a propagation delay of 9 ns at 3.3 V and 7 ns at 5 V, with a static current of 8 uA and a maximum power dissipation of 200 mW.

Feature Summary

• Provides eight independent non-inverting buffer channels for signal conditioning.
• Features three-state outputs to facilitate bus-oriented architectures.
• Operates across a wide 2 V to 6 V supply voltage range.

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify the specific suffix 'DTG' against the manufacturer's official datasheet to confirm the TSSOP-20 package configuration and tape-and-reel orientation. Ensure the component meets RoHS compliance requirements as specified in the latest environmental declarations. Cross-reference the ordering information with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when designing systems requiring octal buffering with three-state control capabilities. It is suitable for applications needing operation between 2 V and 6 V. Consider the TSSOP-20 package for space-constrained designs. Verify that the required drive current and propagation delay specifications align with the system's timing constraints and load requirements.

Part Context

This part belongs to the MC74AC244 family of octal buffers and line drivers. It shares functional similarities with other variants like MC74AC244DTR2G and MC74AC244DWG, differing primarily in packaging and reel specifications. The AC series offers higher speed performance compared to standard 74LS counterparts while maintaining CMOS compatibility.

Replacement Considerations

MC74AC244DTR2G (TSSOP-20 Reel), MC74AC244DWG (SOIC-20 Tube). Verify pinout and electrical characteristics match before substitution.
