74LCXR2245MTC

Overview

The Fairchild Semiconductor 74LCXR2245MTC is a low-voltage bidirectional bus transceiver featuring five-volt tolerant inputs. It operates within a supply voltage range of 2V to 3.6V and supports data rates up to 100 Mbps. The device provides three-state outputs with a maximum output current of 24mA. It is housed in a 20-pin TSSOP package and functions across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Bidirectional data transfer capability between two buses
• Five-volt tolerant input structure for mixed-voltage systems
• Low power consumption design suitable for battery-operated applications

Applications

• Memory bus architectures requiring level shifting
• High-speed data transmission interfaces
• Portable electronic devices with mixed voltage domains

Procurement Notes

Verify the specific suffix 'MTC' corresponds to the 20-TSSOP package configuration. Confirm RoHS compliance status as some listings indicate non-compliance. Ensure the supplier provides official datasheets from Fairchild or onsemi to validate electrical characteristics and pinout definitions before procurement.

Selection Notes

Select this component when interfacing 2V-3.6V logic with 5V tolerant peripherals. The bidirectional nature simplifies circuit design for shared data lines. Consider the 24mA drive strength for moderate capacitive loads. Verify thermal requirements against the -40°C to 85°C operating range for the intended environment.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices. It serves as a standard interface solution for converting between different voltage levels while maintaining signal integrity. The 74LCXR2245 variant specifically emphasizes robustness against electrostatic discharge and noise immunity in high-density digital systems.

Replacement Considerations

Check for direct equivalents such as the 74VCXH2245MTC, which shares similar functional characteristics but may differ in specific electrical parameters or packaging details. Always cross-reference pinouts and voltage tolerances before substitution.
