IDT74LVC4245ASOG

Translators, Level Shifters Overview

The IDT74LVC4245ASOG is an octal bus transceiver manufactured using 0.5 micron CMOS technology, designed for industrial temperature ranges from -40°C to +85°C. It features two separate supply rails: VCCA operates at 5V ± 0.5V, while VCCB operates between 2.7V and 3.6V. The device provides noninverting data transfer with 3-state outputs and ±24mA drive capability. All inputs and I/O are 5V tolerant, supporting hot insertion. It utilizes a common control scheme where the DIR pin determines direction and OE disables ports.

Translators, Level Shifters Feature Summary

• Dual power rail architecture enabling translation between 5V and 3.3V environments
• High output drivers capable of ±24mA current to maintain speed under moderate to heavy loads
• All inputs and I/O pins are 5V tolerant, ensuring compatibility across mixed voltage systems
• Input hysteresis design improves noise margin for reliable asynchronous communication

Translators, Level Shifters Applications

• Mixed voltage systems combining 5V and 3.3V logic levels
• Data communication systems requiring bidirectional bus interfacing
• Telecommunication equipment utilizing asynchronous bus protocols

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix 'SOG' corresponds specifically to the Shrink Small Outline Package (SSOP) variant as defined in the manufacturer's ordering guide. Confirm the component meets RoHS Green standards if environmental compliance is required. Ensure the application environment remains within the specified industrial temperature range of -40°C to +85°C for guaranteed performance parameters.

Translators, Level Shifters Selection Notes

Select this component when designing interfaces between 5V and 3.3V buses requiring high drive strength and 5V tolerance on all pins. The SSOP package offers a compact footprint suitable for space-constrained designs. Consider the propagation delay characteristics and quiescent power consumption when evaluating system timing and power budgets against alternative LVC family devices.

Translators, Level Shifters Part Context

This part belongs to the IDT 74LVC4245A series of octal bus transceivers. It shares functional similarities with other dual-supply level shifters but is distinguished by its specific 0.5 micron CMOS process and 5V-tolerant input structure. The device serves as a bridge for asynchronous data transfer between different voltage domains in digital logic circuits.

Translators, Level Shifters Replacement Considerations

Compatible substitutes include SN74LVC4245 variants from Texas Instruments or CD74LVC4245 from Renesas, provided they match the SSOP-24 package and support the same 5V/3.3V dual-rail operation.
