74LCXZ245SJX

Overview

The onsemi 74LCXZ245SJX is an octal bus transceiver featuring non-inverting bidirectional buffers with three-state outputs. Designed for low-voltage applications, it operates within a supply voltage range of 2.3V to 3.6V and supports 5V tolerant inputs and outputs. The device utilizes advanced CMOS technology to achieve high-speed operation while maintaining low power dissipation. It includes dedicated OE and T/R control pins to manage data flow direction and output states. The SJX suffix indicates availability in tape and reel packaging.

Feature Summary

• Provides five-volt tolerant inputs and outputs for interfacing between different voltage domains
• Maintains high-impedance state during power-up or power-down to prevent bus loading
• Implements patented noise and EMI reduction circuitry for signal integrity
• Supports live insertion and withdrawal operations

Applications

• Bus-oriented memory and disk drive controller systems
• High-density microprocessors
• Consumer electronics requiring low-voltage logic translation

Procurement Notes

Verify the specific ordering code against manufacturer documentation to confirm package type and suffix requirements. Ensure that the OE pin is properly biased with a pull-up resistor if live insertion support is required. Confirm RoHS compliance status and lead-free specifications match project standards before finalizing procurement.

Selection Notes

Select this component when designing systems requiring bidirectional data transfer between 2.5V or 3.3V logic levels and 5V environments. Consider its low quiescent current and high output drive capability for power-sensitive designs. Evaluate propagation delay specifications relative to system clock speeds to ensure timing margins are met.

Part Context

This part belongs to the LCX family of low-voltage CMOS logic devices. It serves as a direct replacement for older LVC series components in many applications. The device is manufactured using advanced CMOS processes optimized for speed and power efficiency in portable and battery-operated equipment.

Replacement Considerations

Check pin compatibility with existing PCB layouts when substituting similar octal transceivers. Verify that alternative packages maintain identical electrical characteristics and voltage tolerances.
