74LCXH16245MTDX

Overview

The onsemi 74LCXH16245MTDX is a low-voltage CMOS bus transceiver featuring 16-bit bidirectional data paths and bus hold functionality. It operates within a supply voltage range of 2 V to 3.6 V, supporting LVTTL and TTL input levels with LVCMOS outputs. The device provides 24 mA high and low output drive currents and exhibits propagation delays of 5.2 ns. Packaged in a TSSOP-48 surface-mount format, it functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates bus hold circuitry to maintain stable logic states during invalid input conditions
• Supports bidirectional data transfer between two buses using non-inverting logic
• Features three-state outputs to isolate the device when disabled

Applications

• High-density memory modules requiring level translation
• Consumer electronics utilizing low-voltage logic interfaces
• Industrial control systems operating in harsh environments

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and moisture sensitivity handling requirements prior to assembly. Ensure the specific suffix matches design specifications for tape-and-reel quantities. Review RoHS compliance documentation for environmental adherence.

Selection Notes

Select this component for designs requiring 16-bit wide data paths with bidirectional capability. The LCXH series offers superior speed compared to standard HC families while maintaining low power consumption. Verify that the 2V to 3.6V supply range aligns with system power rails and that the TSSOP-48 footprint fits the PCB layout constraints.

Part Context

This part belongs to the 74LCXH family of low-voltage CMOS logic devices. It serves as a critical interface component for managing data flow between different voltage domains in complex digital systems. The inclusion of bus hold features distinguishes it from standard transceivers by preventing floating outputs.

Replacement Considerations

Check for equivalent parts such as the 74LVC16245 or 74LVCH16245 from other manufacturers. Ensure pin compatibility and electrical characteristics match before substitution.
