Overview
The CD74FCT543CTQM is a non-inverting bus transceiver manufactured by Harris Corporation. It features one functional unit with eight bits per element and provides three-state outputs. The device operates within a supply voltage range of 4.75V to 5.25V. It is housed in a 24-lead QSOP package with a width of 0.154 inches (3.90mm). The component utilizes CMOS technology and is designed for bidirectional data transfer applications requiring high-speed performance.
Feature Summary
- Non-inverting logic function for direct signal transmission
- Three-state output capability for bus line isolation
- Independent control mechanisms for directional data flow
Applications
- Bidirectional bus architectures
- Memory interface circuits
- I/O expansion systems
Procurement Notes
Verify the specific suffix CTQM confirms the 24-QSOP package configuration. Confirm RoHS compliance status as documentation indicates non-compliance. Ensure the manufacturer is identified as Harris Corporation or its successor entity. Check for moisture sensitivity level requirements during storage and handling procedures before assembly.
Selection Notes
Select this component when a non-inverting, 8-bit transceiver with three-state outputs is required. The 24-QSOP package suits surface-mount designs with limited board space. Verify that the operating voltage range of 4.75V to 5.25V aligns with the system power supply. Consider the CMOS technology characteristics for power consumption and speed requirements.
Part Context
This part belongs to the FCT series of bus transceivers from Harris Corporation. It serves as a digital interface component for transferring data between buses. The device complements other logic families by providing high-speed switching capabilities. It is distinct from registered variants like the CD74FCT543E which includes latch functionality.
Replacement Considerations
Check for equivalent parts from current manufacturers if Harris Corporation production has ceased. Verify pin compatibility and electrical specifications against alternatives such as the CD74FCT543E for functional similarity.
