SN74LVC4245APWRG4

Translators, Level Shifters Overview

The SN74LVC4245APWRG4 is an octal bus transceiver and voltage level shifter from Texas Instruments, designed for asynchronous communication between data buses. It features three-state outputs and operates with a VCCA supply range of 4.5V to 5.5V and a VCCB range of 2.7V to 3.6V. The device provides bidirectional data transfer controlled by a DIR input, allowing movement from A to B or B to A. An OE input enables effective bus isolation. Packaged in a 24-pin TSSOP, it supports LVTTL logic levels and functions within an operating temperature range of -40°C to +85°C.

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package type is TSSOP-24 and the operating temperature range matches industrial requirements. Ensure the voltage domains align with your system's VCCA (4.5V-5.5V) and VCCB (2.7V-3.6V) supplies. Cross-reference the datasheet revision date to confirm current electrical characteristics and pinout definitions before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing 5V logic buses with 3.3V peripherals requiring bidirectional data flow. The VCCA/VCCB configuration allows flexible power domain separation. Consider the propagation delay and output drive strength relative to bus capacitance. Verify that the 24-pin TSSOP package fits the PCB footprint constraints. Ensure the ESD protection levels meet the environmental safety requirements of the target application.

Translators, Level Shifters Part Context

This part belongs to the SN74LVC4245A family of octal bus transceivers. It shares functional similarities with the SN74LVCC4245A but differs in specified voltage ranges. The 'G4' suffix typically denotes lead-free and RoHS-compliant manufacturing. It serves as a bridge for mixed-voltage digital systems, enabling seamless integration between different logic families while maintaining signal integrity across varying power supplies.

Translators, Level Shifters Replacement Considerations

SN74LVC4245APWT offers identical functionality in a TSSOP-24 tape-and-reel package. SN74LVCC4245APWR provides similar voltage shifting capabilities with potentially different electrical specifications. Verify pin compatibility and voltage tolerances before substituting.
