Overview
The 74LCXR162245MTX is a low-voltage, 16-bit bidirectional transceiver from the Fairchild Semiconductor LCX family. It features non-inverting buffers with three-state outputs, designed for bus-oriented applications. The device operates within a supply voltage range of 2V to 3.6V and supports an output current of 12mA for both high and low states. It is housed in a surface-mount package suitable for automated assembly.
Feature Summary
- Provides sixteen non-inverting bidirectional buffer channels
- Features three-state outputs for effective bus management
- Designed specifically for bus-oriented system architectures
Applications
- Bus-oriented digital systems
- Low-voltage memory interface circuits
- Bidirectional data transmission pathways
Procurement Notes
Verify the manufacturer designation, as ON Semiconductor acquired Fairchild's semiconductor business. Confirm the specific suffix 'R' indicates reel packaging if required by your assembly line. Ensure the component matches the 2V-3.6V operating range and 12mA drive capability specified in the official datasheet before integration into your design.
Selection Notes
Select this component when a 16-bit wide bidirectional interface is required at low voltages. The three-state output allows multiple devices to share a common bus without electrical conflict. Consider the 2V minimum supply voltage when designing power rails, ensuring compatibility with other logic levels in the signal chain.
Part Context
This part belongs to the 74LCX series, which offers high-speed performance with low static power consumption. It serves as a bridge between different voltage domains in mixed-signal systems. The 16-bit width reduces pin count compared to using eight 2-bit transceivers, simplifying PCB layout for wide data buses.
Replacement Considerations
The 74LCX16245MTD is a documented substitute offering similar functionality. Verify that the replacement maintains the same 2V-3.6V supply range and 12mA output current specifications to ensure circuit compatibility.
