CD74FCT245M96

Overview

The CD74FCT245M96 is an octal bus transceiver from the FCT logic series by Texas Instruments. It features eight non-inverting channels with three-state outputs, designed for TTL input and output levels. The device operates within a supply voltage range of 4.75 V to 5.25 V. It supports surface-mount installation in a 20-pin SOIC package. Key electrical parameters include a maximum propagation delay of 7 ns at 5 V and a low-level output current capability of 64 mA. The component functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Provides bidirectional data transmission via eight independent channels
• Features three-state outputs to facilitate direct system bus connections
• Supports TTL-compatible logic levels for inputs and outputs

Applications

• High-speed data bus architectures requiring octal buffering
• Memory and disk controller interface circuits
• Communication systems utilizing parallel data transfer

Procurement Notes

Verify the specific manufacturer designation, as the CD74FCT245 part family has been historically associated with Cypress Semiconductor before acquisition by Infineon. Confirm that the source document explicitly identifies Texas Instruments as the current manufacturer or authorized supplier for this specific marking code. Ensure the datasheet matches the 20-pin SOIC physical dimensions and electrical characteristics listed above.

Selection Notes

Select this component when designing systems that require high-speed octal bus interfacing with TTL compatibility. The FCT series offers faster switching speeds compared to standard HC or HCT logic families. Consider the 64 mA sink current capability for driving heavier loads on the bus lines. Verify that the 5 V nominal supply voltage aligns with the target system power rails.

Part Context

This device belongs to the FCT (Fast CMOS Technology) logic family, which bridges the performance gap between standard CMOS and ECL technologies. The CD74 prefix indicates a commercial grade variant manufactured using CMOS processes. As an octal transceiver, it serves as a critical interface element for managing data flow between microprocessors and peripheral devices in complex digital systems.
