74LCX652WM

Overview

The onsemi 74LCX652WM is an octal bus transceiver and register featuring D-type flip-flops within the LCX logic family. It supports low-voltage operation at 2.5V or 3.3V VCC while providing 5V tolerant inputs and outputs for interfacing with 5V signal environments. The device includes control circuitry for multiplexed transmission of data directly from the input bus or from internal registers, which are clocked by appropriate HIGH logic levels. It offers independent output enable pins to manage the transceiver function in both directions.

Feature Summary

• Integrates D-type flip-flops for registered data storage alongside direct bus transmission capabilities
• Provides 5V tolerant inputs and outputs to facilitate safe interfacing between low-voltage and 5V systems
• Features independent output enable controls for managing data flow directionality

Applications

• Low voltage memory interface circuits
• Clock drivers and buffered clocks
• Bus-oriented communications systems

Procurement Notes

Verify the specific manufacturer designation as onsemi, noting that Fairchild Semiconductor was acquired by onsemi. Confirm the package type corresponds to the WM suffix, typically a small outline package. Ensure the component meets the required operating temperature range and voltage specifications for your target application environment before finalizing procurement.

Selection Notes

Select this component when designing systems requiring bidirectional data transfer between 2.5V or 3.3V logic domains and 5V peripherals. The integrated registration feature makes it suitable for applications needing data latching during transmission. Consider the propagation delay and power consumption characteristics relative to other LCX series devices to ensure compatibility with system timing requirements.

Part Context

This part belongs to the LCX series of low-voltage CMOS logic devices, designed for high-speed operations with reduced power consumption. The 74LCX652 specifically addresses the need for registered bus transceivers in portable and battery-powered applications where voltage translation and data integrity are critical. It complements other LCX components like buffers and inverters in comprehensive logic design solutions.
