Overview
The Fairchild Semiconductor 74LCXZ2245MTCX is a low-voltage bidirectional transceiver from the LVC/LCX/Z series. It features eight bits of non-inverting data transmission with three-state outputs in a 20-TSSOP package. The device supports a supply voltage range of 1.4V to 3.6V and provides 5V tolerant inputs and outputs. It includes integrated 26 Ω series resistors for signal integrity.
Feature Summary
- Bidirectional data transmission capability between two buses
- Five-volt tolerant input and output interfaces
- Integrated series resistors for impedance matching
Applications
- Memory card interface circuits
- Bus-oriented system architectures
- Low-voltage embedded controller interconnects
Procurement Notes
Verify the specific suffix 'MTCX' confirms the tape-and-reel packaging format required for automated assembly processes. Confirm RoHS compliance status matches current environmental regulations for your target market. Ensure the manufacturer designation aligns with original Fairchild or ON Semiconductor sourcing channels to guarantee component authenticity and traceability.
Selection Notes
Select this component when designing systems requiring level shifting between 1.8V, 2.5V, and 3.3V logic domains while maintaining compatibility with 5V peripherals. The integrated series resistors simplify PCB layout by reducing external component count. Verify that the 20-TSSOP footprint fits within the available board space constraints.
Part Context
This part belongs to the 74LCXZ family, which extends the standard LCX line with enhanced 5V tolerance characteristics. The Z suffix typically denotes specific electrical enhancements or pin-compatible upgrades within the broader 74LCX logical gate portfolio manufactured by Fairchild Semiconductor.
Replacement Considerations
Direct substitutes include the 74LCX2245MTCX if series resistor integration is not required. Verify pinout compatibility before replacing with generic 74LVC or 74LVXC variants, as electrical characteristics and tolerance levels may differ significantly.
