74ACT11543DW

Buffers, Drivers, Receivers, Transceivers Overview

The 74ACT11543DW is an octal registered transceiver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data transfer rates characterized by propagation delays up to 16 ns. The device features TTL-compatible inputs, high-level output current of -24 mA, and low-level output current of 24 mA. It is housed in a 28-pin SOIC package and functions across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Contains two sets of D-type latches for temporary storage of data flowing in either direction
• Features separate latch enable and output enable inputs for independent control of data flow direction
• Utilizes center-pin VCC and GND configurations to minimize high-speed switching noise

Buffers, Drivers, Receivers, Transceivers Applications

• Temporary storage of bidirectional data flow
• Bus-oriented memory register applications
• Clocking data registers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix (e.g., DW vs DWR) against the manufacturer's latest documentation to confirm packaging type and moisture sensitivity level. Confirm RoHS compliance status and lead finish details directly from the official datasheet or product page before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional data buffering with integrated storage is required. Ensure the system logic levels are compatible with the specified TTL input thresholds. Verify that the 28-pin SOIC footprint matches the PCB layout constraints and that the operating temperature range meets environmental requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT series of advanced CMOS logic devices. It serves as a registered transceiver, combining bus driving capabilities with data latching functionality. The device is designed for high-speed digital systems requiring reliable data retention during transmission between different bus segments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74ACT11543 variants with different suffixes such as DWE4 or DWRG4 for identical electrical specifications but potentially different packaging or environmental compliance attributes.
