IDT74LVC244APGG

Overview

The IDT74LVC244APGG is an octal buffer and line driver manufactured by Renesas Electronics under the LVC logic series. It features 16 input lines and 16 output lines with non-inverting polarity, organized as two 4-bit drivers with separate active-low output enable inputs. The device operates within a supply voltage range of 2.7V to 3.6V and utilizes a TSSOP-20 package. It provides high output drive capabilities of ±24mA and supports hot insertion for data bus communication.

Feature Summary

• Supports hot insertion for safe connection during system operation
• Provides rail-to-rail output swing to enhance noise margins
• Features 5V tolerant inputs and outputs for mixed-voltage interfacing

Applications

• Mixed voltage systems combining 5V and 3.3V logic levels
• Data communication systems requiring bus isolation
• Telecommunication equipment utilizing asynchronous interfaces

Procurement Notes

Verify that the ordering suffix PGG corresponds specifically to the Green Thin Shrink Small Outline Package (TSSOP) variant. Confirm the temperature grade matches the industrial range of -40°C to +85°C. Ensure the part number includes the 'A' designation for the specific device revision. Cross-reference the manufacturer IDT/Renesas documentation to validate the pinout configuration against your schematic requirements before procurement.

Selection Notes

Select this component when an octal buffer with 3-state outputs is required for driving moderate to heavy loads. The ±24mA drive capability makes it suitable for applications needing robust signal integrity. Choose this part over standard variants if 5V tolerance is necessary for interfacing with legacy 5V devices while operating at lower voltages. Verify package availability in TSSOP format for surface mount assembly constraints.

Part Context

This component belongs to the 74LVC244A family of octal buffers. It shares functional similarities with other LVC series drivers but is distinguished by its specific package type and manufacturing origin. The IDT branding indicates its lineage from Integrated Device Technology, now part of Renesas Electronics. It serves as a direct replacement for standard 74LVC244 devices in designs requiring the specified package and electrical characteristics.

Replacement Considerations

IDT74LVC244AQG is a confirmed substitute part number.
