CD74HCT245M96

Overview

The CD74HCT245M96 is an octal bus transceiver from the Texas Instruments CDx4HC(T)245 series, utilizing high-speed CMOS technology. It features three-state outputs and non-inverting logic functionality. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 20-pin SOIC package. It is designed for bidirectional data transmission between buses and peripheral devices.

Feature Summary

• Provides octal (8-bit) bidirectional data transfer capability between two buses.
• Features three-state outputs to facilitate direct connection to system data lines without additional buffering.
• Utilizes high-speed CMOS technology for low power consumption and fast switching speeds.
• Includes direction control and output enable functions for flexible bus management.

Applications

• Mobile applications requiring compact bus interfacing
• Computing systems for data bus expansion
• Consumer products with high-density logic requirements

Procurement Notes

Verify the specific suffix M96 against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the target PCB footprint and reflow soldering profile. Confirm RoHS compliance status as defined in the latest environmental documentation.

Selection Notes

Select this component when an octal, non-inverting, three-state bus transceiver is required for 5V logic systems. Compare propagation delay and drive current specifications against alternative HC or HCT series parts if signal integrity or loading conditions are critical constraints in the design.

Part Context

This part belongs to the CD74HCT family of high-speed CMOS logic devices manufactured by Texas Instruments. The '245' designation specifically identifies it as an octal bus transceiver. The 'M96' suffix typically denotes the SOIC-20 package variant with specific reel packaging configurations.

Replacement Considerations

Compatible substitutes include other octal bus transceivers such as the SN74HCT245 or equivalent parts from other manufacturers offering identical pinouts and electrical characteristics. Verify logic family voltage compatibility before substitution.
