74ACTQ16543MTDX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ16543MTDX is a 16-bit registered transceiver with 3-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 operating temperature range of -40°C to +85°C. The device utilizes FACT Quiet Series technology for improved dynamic threshold performance and guaranteed simultaneous switching noise levels. It features independent registers for A and B buses with separate control logic for each byte, allowing multiplexed real-time and stored data transfers.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'X' indicates tape and reel packaging as documented in the datasheet. Confirm that the component is sourced from Fairchild Semiconductor or authorized successors, noting the historical context of the manufacturer. Ensure the package type matches the 56-lead TSSOP specification (JEDEC MO-153) required for the design. Cross-reference the part number against current availability lists as legacy components may have limited stock.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit bidirectional data transfer with latching capabilities at the 5V logic level. The device is suitable for applications demanding low simultaneous switching noise and precise pin-to-pin skew control. Consider the 56-lead TSSOP package constraints regarding board space and thermal management. Ensure the system power supply remains within the 4.5V to 5.5V range to maintain specified electrical characteristics.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ACT family of high-speed CMOS logic devices. It is functionally equivalent to the 74LCX16543 but operates at a higher voltage level (5V vs 2V/3.6V). The 74ACTQ16543 is a 16-bit version of the ACTQ543, offering expanded data width for complex bus architectures. It represents a specialized solution for byte-multiplexed data handling in industrial and commercial electronics.
