CY74FCT543TQCT

Overview

The CY74FCT543TQCT is an octal bus transceiver from the Texas Instruments FCT logic series. It features non-inverting data paths with three-state outputs, enabling bidirectional communication on a single bus. The device operates within a supply voltage range of 4.75V to 5.25V and supports TTL input and output levels. It is housed in a 24-pin SSOP package and is rated for operation between -40°C and +85°C.

Feature Summary

• Provides bidirectional data transfer capability across eight channels
• Features three-state outputs for effective bus isolation
• Supports non-inverting signal transmission

Applications

• Bidirectional bus-oriented memory and register transfers
• Control signals driving multiple receivers
• A/D and D/A converters interfacing

Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate different packaging or temperature ratings. Confirm current availability status, as this component may be discontinued or subject to long lead times. Ensure the selected variant matches the required pinout and electrical specifications for the target application design.

Selection Notes

Select this component when designing systems requiring high-speed bidirectional data transfer with low power consumption. Verify that the system voltage aligns with the 4.75V to 5.25V operating range. Consider the propagation delay characteristics relative to the system clock speed to ensure timing requirements are met during data transitions.

Part Context

This part belongs to the CY74FCT543T family of registered transceivers. It shares functional similarities with other FCT series devices but is distinguished by its octal configuration and specific control inputs. It serves as a key interface component in digital logic circuits requiring reliable data latching and transmission.
