74LCXZ245SJ

Overview

The onsemi 74LCXZ245SJ is an eight-channel non-inverting bidirectional bus transceiver with three-state outputs, housed in a 20-lead Small Outline Package (SOP). It operates within a supply voltage range of 2.3V to 3.6V and supports 5V tolerant inputs and outputs. The device features a maximum propagation delay of 7.0 ns at 3.3V and provides output drive currents up to 24 mA at 3.0V. It includes power-down high impedance protection and implements patented noise reduction circuitry.

Feature Summary

• Provides five-volt tolerant input and output capabilities for interfacing low-voltage logic with 5V signal environments.
• Maintains high impedance state during power-up or power-down to prevent intermittent loading and glitching.
• Incorporates patented noise and EMI reduction circuitry to enhance signal integrity.

Applications

• Bus-oriented data transmission applications
• Low voltage to 5V signal environment interfacing
• Live insertion and withdrawal support

Procurement Notes

Verify the specific package designation M20D corresponds to the requested 20-lead SOP form factor. Confirm that the ordering code matches the exact suffix requirements for lead-free compliance per JEDEC standards. Ensure compatibility with the intended operating temperature range of -40°C to 85°C.

Selection Notes

Select this component when bidirectional data transfer between buses with differing voltage levels is required. The 5V tolerance allows direct connection to legacy 5V systems without additional level shifting components. Consider the 24 mA drive capability for driving moderate capacitive loads on the bus lines.

Part Context

This device belongs to the LCX family of low-voltage CMOS logic products. It shares functional similarities with other octal bus transceivers but is distinguished by its specific 5V tolerance and low-power characteristics. The SJ suffix identifies the physical package type as a 20-lead SOP.

Replacement Considerations

Direct pin-compatible replacements include the 74LCX245 from various manufacturers such as Fairchild, NXP, and ON Semiconductor. Verify that substitute parts maintain the same 5V tolerance specifications and package dimensions.
