74ACT16244MTDX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT16244MTDX is a 16-bit buffer and line driver featuring three-state outputs, designed for memory address drivers, clock drivers, and bus-oriented transmitters or receivers. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. The device utilizes a 48-lead Thin Shrink Small Outline Package (TSSOP) with JEDEC MO-153 specifications. Key electrical characteristics include TTL-compatible inputs, output source/sink currents up to 24mA, and propagation delays typically ranging from 2.5ns to 7.3ns at 5.0V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering code suffix against manufacturer documentation to confirm package type and reel configuration. Ensure compatibility with the required supply voltage range of 4.5V to 5.5V and the specified operating temperature limits. Confirm that the 48-lead TSSOP footprint matches the target PCB design constraints.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit wide data path requires buffering with high drive strength and three-state isolation. The ACT series is appropriate for systems requiring TTL input compatibility and operation at standard 5V logic levels. Consider the nibble-controlled architecture if independent control of four-bit segments is necessary for the application design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AC/ACT logic family, specifically the 16-bit buffer variant. It is functionally related to the 8-bit 74AC244/ACT244 but provides double the channel count in a similar package format. The device is manufactured using Fairchild's FACT/c165 CMOS process, ensuring robust performance in high-density digital applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct functional equivalents include the 74AC16244 and 74ACT16244 in SSOP packages. Cross-manufacturer replacements such as the SN54ACT16244 may be considered, provided pinout and electrical specifications are verified against the original datasheet requirements.

Buffers, Drivers, Receivers, Transceivers FAQ

How is the three-state functionality controlled?

The device features separate Output Enable (OE_n) inputs for each of the four nibbles. When OE_n is LOW, the outputs are active; when HIGH, they enter a high-impedance state.

What is the input compatibility of the ACT version?

The 74ACT16244 has TTL-compatible inputs, allowing it to interface directly with TTL logic families without additional level shifting components.
