MC74LVXC3245DTRG

Translators, Level Shifters Overview

The MC74LVXC3245DTRG is a configurable dual-supply octal transceiver with three-state outputs designed for 3 V systems. It features a dedicated 3.0 V A port and a B port that tracks the VCCB supply level, which ranges from 3.0 V to 5.0 V. The device supports bidirectional data flow controlled by Transmit/Receive inputs and allows the B port and VCCB pin to float simultaneously when Output Enable is High. It operates within a temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Configurable dual-supply architecture enabling interface between 3.0 V and 3.0 V/5.0 V buses
• Allows B port and VCCB voltage source to float simultaneously when OE is High
• Control inputs compatible with TTL levels
• Outputs capable of sourcing and sinking up to 24 mA

Translators, Level Shifters Applications

• PCMCIA configurable I/O applications
• Real-time configurable I/O interfaces
• ISA bus standard connections (IEEE P996)

Translators, Level Shifters Procurement Notes

Verify the specific package suffix against the datasheet ordering information. The 'DT' suffix indicates TSSOP-24 packaging, while 'DW' indicates SOIC-24. Confirm the 'G' suffix denotes Pb-Free status as per manufacturer specifications. Ensure the component matches the required operating voltage conditions for both VCCA and VCCB pins before integration.

Translators, Level Shifters Selection Notes

Select this component for designs requiring voltage translation between fixed 3.0 V hosts and variable 3.0 V to 5.0 V peripheral buses. It is suitable for low-power notebook designs due to minimal quiescent power consumption. Ensure the application requires simultaneous floating capability on the B port during card insertion or removal events.

Translators, Level Shifters Part Context

This device belongs to the 74LVXC series of logic integrated circuits manufactured by onsemi. It functions as an octal bus transceiver providing non-inverting data transfer. The part is functionally compatible with the standard 74 Series 245 devices but offers enhanced configurability for dual-supply environments.

Translators, Level Shifters FAQ

How does the device handle PCMCIA card insertion?

The device allows the VCCB voltage source pin and I/O pins on the B port to float when OE is High, which is necessary for buffering data to and from PCMCIA sockets during card insertion and removal.

What are the supply voltage requirements?

VCCA must be tied to a 3.0 V supply. VCCB accepts a supply level ranging from 3.0 V to 5.0 V, configuring the B port I/O pins to match the VCCB voltage.
