74LCX32245G

Overview

The Fairchild Semiconductor 74LCX32245G is a low-voltage CMOS bus transceiver featuring four independent 8-bit channels, totaling 32 bits of data transmission capability. It operates within a supply voltage range of 2V to 3.6V and utilizes a 96-pin FBGA package with dimensions of 13.5mm by 5.5mm. The device provides tri-state outputs capable of sourcing and sinking up to 24mA. Designed for high-speed applications, it supports input levels compatible with LVTTL and TTL standards while driving LVCMOS loads. The component functions as a non-inverting transceiver with propagation delays specified under standard test conditions.

Feature Summary

• Provides bidirectional data transfer across four independent 8-bit buses
• Features tri-state outputs for effective bus line management
• Supports interface between low-voltage logic and 5V tolerant environments

Applications

• High-density memory bus architectures
• Data acquisition systems requiring multi-channel isolation
• Industrial control networks utilizing parallel data transmission

Procurement Notes

Verify the specific suffix 'G' against official onsemi documentation to confirm pinout compatibility and RoHS status. Confirm that the 96-FBGA package matches your PCB footprint requirements. Check current manufacturing status as this series may be discontinued or superseded by newer revisions. Ensure thermal dissipation capabilities align with your system's operating temperature range of -40°C to +85°C.

Selection Notes

Select this component when designing systems requiring multiple isolated 8-bit data paths in a compact form factor. The 96-FBGA package offers significant pin density compared to TSSOP alternatives. Consider the 2V to 3.6V operating range for compatibility with modern low-power logic families. Evaluate the 24mA drive strength against the capacitive load of the destination buses to ensure signal integrity at target clock speeds.

Part Context

This device belongs to the 74LCX family of low-voltage CMOS logic components originally manufactured by Fairchild Semiconductor, now part of onsemi. The LCX series is characterized by its ability to operate at lower voltages than traditional 5V logic while maintaining compatibility with legacy interfaces. The 32245 designation indicates a wide-bus transceiver configuration, distinct from the narrower 16-bit variants like the 16245.

Replacement Considerations

Publicly confirmed substitute part numbers include 74LCX16245MTDX and Renesas 74LVCH32245ABFG.
