SN74LVC4245ADW

Translators, Level Shifters Overview

The SN74LVC4245ADW is an octal bus transceiver and voltage-level shifter manufactured by Texas Instruments. It operates with a dual-supply configuration, supporting VCCA from 4.5 V to 5.5 V and VCCB from 2.7 V to 3.6 V. The device features eight channels in a non-inverting direction, housed in a 24-SOIC package. Key electrical parameters include a propagation delay of 2.7 ns, output currents of ±24 mA, and a maximum operating temperature of +85 °C.

Translators, Level Shifters Feature Summary

• Provides bidirectional data transmission between buses with different voltage levels
• Supports asynchronous communication via independent A and B bus supplies
• Features three-state outputs for effective bus isolation when disabled

Translators, Level Shifters Applications

• Asynchronous communication between data buses
• Voltage translation between 3.3-V and 5-V systems
• Memory and memory mapping applications

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-24 package and tube packaging format. Confirm RoHS compliance status and ensure the component meets JESD 17 latch-up performance requirements exceeding 250 mA. Check for green product specifications regarding antimony and bromine content before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic families requiring distinct supply voltages, specifically translating between 3.3-V and 5-V domains. Ensure the design accommodates the separate VCCA and VCCB power pins. Verify that the required data rate does not exceed the specified propagation delay limits for the target application environment.

Translators, Level Shifters Part Context

This part belongs to the SN74LVC4245A series of octal bus transceivers. It is designed to facilitate data transfer between buses operating at different voltage levels without requiring board layout changes compared to standard 245 devices. The LVC series offers low voltage CMOS technology for reduced power consumption.

Translators, Level Shifters Replacement Considerations

SN74LVCC4245ADW: Offers similar functionality but supports a wider VCCB range up to 5.5 V.
