74ACT16244DGG

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT16244DGG is a 16-bit buffer and line driver from Texas Instruments' ACT logic family, housed in a 48-pin TSSOP package. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features TTL-compatible CMOS inputs and three-state outputs with symmetric drive capabilities, providing a high-level output current of -24 mA and a low-level output current of 24 mA. Static current consumption is typically 8 µA, while operating supply current reaches 1 mA. It supports a minimum operating temperature of -40°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides true and complementary (low-active) output enable inputs for flexible bus control
• Utilizes distributed VCC and GND pin configurations to minimize high-speed switching noise
• Features flow-through architecture optimized for printed circuit board layout efficiency

Buffers, Drivers, Receivers, Transceivers Applications

• Three-state memory address drivers
• Clock drivers
• Bus receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DGG corresponds to the 48-TSSOP plastic shrink small outline package. Confirm that the component status is End-of-Life, as manufacturer discontinuation may impact long-term availability. Ensure input voltage levels match TTL compatibility requirements for the target system design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between TTL and CMOS logic families requiring 16-bit wide data paths. The ACT technology offers higher speed than standard ALS series while maintaining CMOS power efficiency. Verify that the 48-TSSOP footprint fits the available PCB area compared to standard SOIC packages.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Widebus family, designed to double I/O pin density within the same PCB area as standard small outline packages. It is part of the EPIC enhanced high-performance injection CMOS process, offering typical latch-up immunity of 500 mA at 125°C.
