74LVT2245PW,112

Overview

The Nexperia 74LVT2245PW,112 is an octal bus transceiver featuring integrated 30 Ω output termination resistors and 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V. The device utilizes BiCMOS technology for high-speed performance and provides an output capability of +12 mA and -12 mA. It supports TTL input and output switching levels and includes overvoltage tolerant inputs up to 5.5 V. The component is housed in a TSSOP20 package (SOT360-1) and functions with direction control via DIR and OE pins.

Feature Summary

• Integrated 30 Ω output termination resistors for signal integrity
• Bus hold data inputs eliminate the need for external pull-up resistors
• IOFF circuitry enables partial power-down mode operation
• Supports live insertion and extraction without bus current loading

Applications

• Octal bidirectional bus interface systems
• Direct interfacing with TTL level logic circuits
• High-speed data transmission lines requiring termination

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP20 plastic thin shrink small outline package variant. Confirm that the required temperature range matches the specified -40 °C to +85 °C operational limits. Ensure design compatibility with the 2.7 V to 3.6 V supply voltage constraints before procurement.

Selection Notes

Select this component when designing systems requiring integrated termination resistors to reduce external component count. It is suitable for applications needing direct TTL interfacing with overvoltage tolerance. Consider the TSSOP20 package dimensions if PCB space is constrained relative to standard SO packages.

Part Context

This part belongs to the 74LVT/LVTH family of logic devices manufactured by Nexperia. It serves as an octal transceiver variant distinguished by its internal termination resistors. The PW suffix indicates the TSSOP20 package type, differentiating it from the D package variant which uses an SO20 form factor.

Replacement Considerations

The 74LVTH2245PW,112 is functionally equivalent and shares the same package and specifications. Verify pinout compatibility and electrical characteristics against the original requirement before substitution.
