CY74FCT2543CTSOCT

Overview

The CY74FCT2543CTSOCT is an octal registered transceiver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting channels with three-state outputs housed in a 24-SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. Key electrical specifications include a propagation delay of 5.5 ns, a low-level output current of 12 mA, and a high-level output current of -15 mA. It functions as a latched transceiver suitable for surface mount installation across an operating temperature range of -40°C to +85°C.

Feature Summary

Octal Registered Transceiver Architecture
Three-State Output Capability
TTL Compatible Input and Output Levels

Applications

High-speed data bus interfacing
Memory buffer applications
I/O port expansion systems

Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature grade (-40°C to +85°C) and 'SOCT' denotes the SOIC-24 tube packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with 5V logic families given the specified voltage and current parameters.

Selection Notes

Select this component when an octal registered transceiver with latching functionality is required for bus isolation. The FCT series offers faster switching speeds compared to standard 74LS logic. Verify that the 24-pin SOIC footprint fits the PCB layout constraints and that the 12 mA/15 mA drive currents meet the load requirements of the destination circuitry.

Part Context

This part belongs to the CY74FCT2543T family of registered bus transceivers. It serves as a bridge between microprocessors and peripheral devices, providing temporary storage and direction control for data lines. The registered nature allows data capture on clock edges, ensuring stable bus operations during transitions.
