74LCXR162245MTD

Overview

The Fairchild Semiconductor 74LCXR162245MTD is a low-voltage 16-bit bidirectional transceiver featuring non-inverting buffers with three-state outputs. It operates within a supply voltage range of 2 V to 3.6 V and supports LVTTL/TTL input levels with LVCMOS output levels. The device provides maximum high-level output current of -24 mA and low-level output current of 24 mA, with a typical propagation delay of 5.2 ns at 50 pF load capacitance. It is housed in a 48-pin TSSOP package measuring 12.5 x 6.1 x 0.9 mm and functions reliably between -40 °C and +85 °C.

Feature Summary

• Contains sixteen non-inverting bidirectional buffers designed for bus-oriented applications
• Features three-state outputs to facilitate efficient data transfer on shared buses
• Supports 5V tolerant inputs allowing interface between different voltage domains

Applications

• Bus-oriented data transmission systems
• Memory module interfacing
• High-density data routing in communication equipment

Procurement Notes

Verify the specific suffix 'MTD' confirms the 48-pin TSSOP package and tape-and-reel or tube availability as per the manufacturer's latest documentation. Ensure the component meets RoHS compliance standards if required by your assembly process. Cross-reference the exact part number with official distributor catalogs to confirm current production status and lead times before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring 16-bit wide bidirectional data paths with low voltage operation. It is suitable for applications needing compatibility between 3.3V logic families and 5V tolerant interfaces. Consider the 48-pin TSSOP footprint for PCB layout constraints and ensure the operating temperature range aligns with the environmental conditions of the target application.

Part Context

This device belongs to the 74LCX series of low-voltage CMOS logic components manufactured by Fairchild Semiconductor (now ON Semiconductor). The LCX family is characterized by high speed and low power consumption, making it ideal for portable and battery-operated devices. The 16245 variant specifically addresses the need for wide-bus data transfer in modern digital systems.

Replacement Considerations

The 74LCX16245MTDX is a direct functional equivalent within the same product line. Verify pinout compatibility and electrical specifications against the original datasheet before substitution. Other variants in the 74LCX16245 family may offer different packaging options but maintain identical logical functionality.
