74LCX16245MTDX-T

Overview

The Fairchild Semiconductor 74LCX16245MTDX-T is a dual bus transceiver from the 74LCX logic family, housed in a 48-pin TSSOP package. It provides two non-inverting 16-bit bidirectional channels with LVCMOS outputs and LVTTL/TTL input compatibility. The device operates within a supply voltage range of 2V to 3.6V, supporting output currents of ±24mA. It features a maximum propagation delay of 5.2ns at 50pF load capacitance and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing two independent 16-bit bidirectional data paths
• Input level compatibility with LVTTL and TTL standards for mixed-voltage interfacing
• Bus hold functionality to maintain signal states during undefined conditions

Applications

• High-speed data bus interfaces in embedded systems
• Level shifting between low-voltage logic domains and 5V tolerant inputs
• Bidirectional data buffering in portable electronic devices

Procurement Notes

Verify that the suffix 'T' corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Confirm the manufacturer designation as Fairchild Semiconductor or its successor entity onsemi, as corporate transitions may affect part marking and documentation availability. Ensure the component meets current RoHS compliance standards before integration into final assemblies.

Selection Notes

Select this component when designing systems requiring high-density 16-bit data transfer with minimal power consumption. The wide input tolerance allows direct connection to legacy 5V systems without additional level shifters. The TSSOP-48 package offers a compact footprint suitable for space-constrained PCB layouts while maintaining adequate thermal performance for continuous operation.

Part Context

This device belongs to the 74LCX series, which utilizes advanced CMOS technology to achieve high-speed operation with low power dissipation. The LCXH variant specifically includes bus hold features to prevent floating inputs. As a standard logic component, it serves as a fundamental building block for digital communication interfaces in consumer electronics and industrial control applications.

Replacement Considerations

The 74LCX16245MTDX is listed as a similar replacement for discontinued parts such as the 74LCX32245GX and 74LCX16245GX.
