CD74HC243M96

Overview

The CD74HC243M96 is a high-speed CMOS bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features four non-inverting channels per chip. The device utilizes a 14-pin SOIC surface-mount package with dimensions of 8.65 mm in length, 3.91 mm in width, and 1.58 mm in height. It supports a maximum propagation delay of 90 ns at 2 V with a 50 pF load and functions reliably across an operating temperature range from -55 °C to +125 °C.

Feature Summary

• Provides bidirectional data transmission through four independent non-inverting channels.
• Features CMOS input and output levels compatible with standard logic families.
• Supports surface mount installation for automated PCB assembly processes.

Applications

• Bidirectional data bus architectures requiring signal isolation or buffering.
• System interconnects between microprocessors and peripheral devices.
• Memory interface circuits utilizing parallel data transfer protocols.

Procurement Notes

Verify the specific suffix M96 corresponds to the SOIC-14 package configuration when sourcing. Confirm RoHS compliance status via official manufacturer documentation prior to integration. Ensure thermal management aligns with the specified -55 °C to +125 °C operational range for the intended application environment.

Selection Notes

Select this component for applications requiring low-voltage operation down to 2 V with high-speed performance. The 14-pin SOIC form factor suits space-constrained designs needing four-channel isolation. Evaluate propagation delay specifications against system timing requirements to ensure signal integrity during data transfers.
