74LCXP16245MTDX

Overview

The Fairchild Semiconductor 74LCXP16245MTDX is a dual bus transceiver from the 74LCX logic family. It integrates two non-inverting bidirectional buffers, each with sixteen channels and three-state outputs. The device operates within a supply voltage range of 2 V to 3.6 V. It supports LVTTL and TTL input levels while providing LVCMOS output levels. Key electrical parameters include a maximum propagation delay of 5.2 ns at 50 pF load capacitance. Output drive capabilities are specified as -24 mA for high level and 24 mA for low level. The component is housed in a 48-pin TSSOP package.

Feature Summary

• Integrates two independent 16-bit bidirectional buffer channels for efficient data routing
• Features three-state outputs to facilitate multiple driver connections on shared buses
• Provides direct interface compatibility between LVTTL/TTL inputs and LVCMOS outputs

Applications

• Bus-oriented memory mapping applications
• High-density data acquisition systems
• Consumer electronics requiring bidirectional data transfer

Procurement Notes

Verify the specific ordering suffix 'MTDX' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements if mandated by your project standards. Cross-reference the part number with official Fairchild or ON Semiconductor documentation to validate active status and availability before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring wide parallel data paths with bidirectional control. The 16-bit width reduces pin count compared to narrower alternatives. Verify that the system operating voltage falls within the 2 V to 3.6 V range. Confirm that the LVTTL/TTL input thresholds align with the source logic family. Consider the 48-pin TSSOP footprint for PCB layout constraints.

Part Context

This device belongs to the 74LCX series, which utilizes CMOS technology for low power consumption and high speed. The LCX family is designed for low-voltage digital applications. The 74LCXP variant typically denotes specific packaging or testing configurations within the standard LCX line. It serves as a bridge between different logic families in mixed-voltage environments.

Replacement Considerations

The 74LCX16245MTD is a closely related variant without the 'P' suffix, potentially differing in packaging or testing criteria. Verify functional equivalence and pinout compatibility before substitution. Consult official replacement guides to ensure no changes in electrical characteristics or package dimensions affect the design.
