74LVT2245D,112

Overview

The Nexperia 74LVT2245D,112 is an octal bus transceiver featuring integrated 30 Ohm termination resistors and 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V. The device includes output enable (OE) and send/receive (DIR) control pins for direction management. It utilizes BiCMOS technology to provide high-speed performance with output capabilities of +12 mA and -12 mA. Inputs are overvoltage tolerant up to 5.5 V, allowing direct interface with TTL levels.

Feature Summary

• Integrated 30 Ohm output termination resistors
• Octal bidirectional bus interface with 3-state buffers
• Bus hold data inputs eliminate need for external pull-up resistors

Applications

• High-speed data transmission lines
• Memory bus interfaces
• Control signal routing in embedded systems

Procurement Notes

Verify the specific suffix '112' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the operating temperature range meets system requirements before finalizing procurement.

Selection Notes

Select this component when designing 3.3 V logic systems requiring precise impedance matching via built-in termination resistors. It is suitable for applications needing overvoltage tolerance on inputs while maintaining compatibility with 5 V tolerant signals. Consider the SOIC-20 package constraints and thermal dissipation characteristics during PCB layout.

Part Context

This part belongs to the 74LVT family of low-voltage CMOS logic devices manufactured by Nexperia. It is functionally related to other octal transceivers like the 74LVTH2245 but distinguished by its specific integration of termination resistors and BiCMOS process technology designed for enhanced speed and drive capability at 3.3 V.
