74LVXC3245WMX

Translators, Level Shifters Overview

The onsemi 74LVXC3245WMX is an 8-bit dual-supply configurable voltage interface transceiver with 3-STATE outputs. It operates with a fixed VCCA of 2.7V to 3.6V and a flexible VCCB range of 3.0V to 5.5V. The device features bidirectional data flow, TTL-compatible control inputs, and output drive capabilities of up to 24 mA. Propagation delays typically range from 1.0 ns to 9.5 ns depending on direction and load conditions. It is housed in a 24-pin SOIC package.

Translators, Level Shifters Feature Summary

• Configurable B Port tracks VCCB supply level for mixed voltage interfacing
• Allows B Port and VCCB to float simultaneously when OE is HIGH
• Implements proprietary EMI reduction circuitry
• Functionally compatible with the 74 series 245

Translators, Level Shifters Applications

• PCMCIA configurable I/O applications
• Real-time configurable I/O interfaces
• Mixed 3V/5V bus environments

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'X' indicates tape and reel packaging as per datasheet ordering codes. Confirm the part number corresponds to the 24-pin SOIC (M24B) package variant. Check current availability status as legacy Fairchild parts may have transitioned or discontinued statuses under ON Semiconductor management systems.

Translators, Level Shifters Selection Notes

Select this component when interfacing between a fixed 3V host system and variable 3V-to-5V peripheral buses. Ensure the application requires the ability to float the B Port during high-impedance states, such as hot-swappable card slots. Validate that input levels are compatible with TTL logic standards for control signals.

Translators, Level Shifters Part Context

This device belongs to the LVXC family of low-voltage CMOS translating transceivers. Originally manufactured by Fairchild Semiconductor, it is now distributed by ON Semiconductor following their integration. The part serves as a bridge for systems requiring dynamic voltage level translation without external configuration hardware.
