MC74ACT244DTR2G

Overview

The MC74ACT244DTR2G is an octal buffer and line driver manufactured by onsemi, belonging to the AC logic family. It features eight non-inverting inputs with three-state outputs controlled by separate enable signals. The device operates within a supply voltage range of 2 V to 6 V and utilizes a TSSOP-20 surface-mount package. Key electrical characteristics include a propagation delay of 15 ns at 5 V and output drive currents of ±24 mA. It supports industrial operating temperatures from -40°C to +85°C.

Feature Summary

• Provides octal buffering for high-speed data transmission applications
• Features three-state outputs to facilitate bus-oriented architectures
• Ensures TTL-compatible input thresholds for system integration

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• High-speed data transceivers

Procurement Notes

Verify the specific ordering suffix DTR2G to confirm the tape-and-reel packaging format and lead-free status. Ensure the component matches the required TSSOP-20 footprint and verify RoHS compliance documentation prior to final procurement decisions.

Selection Notes

Select this component when designing systems requiring octal buffering with TTL-compatible inputs and wide supply voltage flexibility. It serves as a suitable alternative to standard HC or HCT families where higher speed and broader voltage operation are necessary.

Part Context

This part belongs to the MC74ACT244 series of octal buffers. It shares functional similarities with other members like the MC74AC244 but offers enhanced input compatibility. The device is designed for general-purpose digital logic applications requiring reliable signal isolation and driving capabilities.

Replacement Considerations

Compatible substitutes include the MC74AC244DTR2G and MC74ACT244ADTR2G. Verify pinout consistency and ensure that the replacement maintains the same three-state control logic and package dimensions.
