74ACT18825MTDX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT18825MTDX is an 18-bit non-inverting buffer and line driver featuring three-state outputs, housed in a 56-lead Thin Shrink Small Outline Package (TSSOP). It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range of -40°C to +85°C. The device contains two independent nine-bit buffers with separate output enable controls for each byte. Outputs provide 24mA source and sink current capability, while inputs are TTL-compatible.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Contains eighteen non-inverting buffers with three-state outputs designed for memory, address, and clock driving applications.
• Features byte-controlled operation with separate three-state control inputs for each nine-bit segment.
• Outputs capable of sourcing and sinking 24mA to drive wider address or data paths carrying parity.

• Memory drivers
• Address drivers
• Clock drivers
• Bus-oriented transmitter/receiver systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the datasheet ordering codes. The 'X' suffix indicates tape and reel packaging. Confirm that the component meets the required operating temperature and voltage specifications for the target application environment before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an 18-bit wide bus interface is required with independent byte-level control. Ensure the design accommodates the 56-lead TSSOP footprint. Verify that the system logic levels align with the specified TTL-compatible input thresholds and that the power supply remains within the 4.5V to 5.5V range.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the ACT series of high-speed CMOS logic devices. It functions as a dual nine-bit buffer, allowing flexible configuration for full 18-bit operation by shorting control pins or independent byte handling. The broadside pinout facilitates easier printed circuit board layout compared to traditional configurations.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-to-pin replacements from other manufacturers offering equivalent 18-bit buffer specifications. Verify that any substitute maintains the same 56-lead TSSOP package dimensions and electrical characteristics, including the 24mA output drive strength and three-state functionality.
