CD74FCT245M

Overview

The CD74FCT245M is a BiCMOS octal bus transceiver manufactured by Harris Corporation. It features non-inverting logic with three-state outputs and operates within a supply voltage range of 4.5V to 5.5V. The device is housed in a 20-SOIC package with a width of 7.50mm. It supports a maximum operating temperature of 125°C and includes direction control functionality for bidirectional data transfer.

Feature Summary

• BiCMOS technology implementation for high-speed performance
• Octal configuration providing eight-bit data transfer capability
• Three-state outputs enabling direct system bus interfacing
• Direction control input for managing signal flow

Applications

• Memory map controllers
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify the manufacturer designation, as Harris Corporation assets were acquired by Texas Instruments. Confirm RoHS compliance status, as older Harris-branded components may not meet current environmental regulations. Ensure the 20-SOIC package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when an octal bus transceiver with BiCMOS speed characteristics is required. The 20-SOIC package offers a balance between pin count and board space. Verify that the 5V logic level compatibility aligns with the connected system components to ensure proper signal integrity and voltage thresholds.

Part Context

This part belongs to the 74FCT series of fast CMOS logic devices. It serves as a standard interface solution for connecting microprocessors to memory or peripheral devices. The 'CD' prefix typically denotes commercial temperature range variants within the broader family of compatible logic transceivers.

Replacement Considerations

Compatible substitutes include the CD74FCT245DTQM and CD74FCT245SM from Harris Corporation/Texas Instruments. These alternatives offer similar functional specifications but differ in package types such as QSOP or SSOP. Verify pinout compatibility and electrical parameters before substitution.
