74LVT2241DB,118

Overview

The Nexperia 74LVT2241DB,118 is an octal buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V. The device includes integrated series termination resistors of 30 Ω per output channel. It supports BiCMOS technology for high-speed performance and provides an output drive capability of +12 mA and -12 mA. Inputs are overvoltage tolerant up to 5.5 V, allowing direct interfacing with TTL levels and 5 V systems. The component utilizes bus hold data inputs to eliminate the need for external pull-up resistors on unused lines.

Feature Summary

• Integrated 30 Ω series termination resistors in each output path
• Bus hold data inputs to define logic states without external components
• Overvoltage tolerant inputs compatible with 5.5 V signals
• Power-up 3-state functionality to prevent bus contention

Applications

• Octal bus interface applications
• Systems requiring live insertion and extraction
• Mixed 3.3 V and 5 V logic environments

Procurement Notes

Verify the specific package designation matches the required footprint. The 'D' suffix indicates an SO20 plastic small outline package (SOT163-1). Confirm that the ordering code includes the ',118' suffix for correct reel packaging specifications. Ensure design compatibility with the specified 2.7 V to 3.6 V operating voltage range before finalizing procurement.

Selection Notes

Select this component when designing circuits that require octal buffering with built-in impedance matching. The integrated 30 Ω resistors simplify layout by removing the need for discrete termination components. Verify that the application environment remains within the -40 °C to +85 °C temperature specification. Consider the 5.5 V input tolerance if interfacing directly with higher voltage buses.

Part Context

This part belongs to the 74LVT logic family, designed for low-voltage CMOS applications. It serves as a buffer or line driver variant within the broader 74-series logic catalog. The device is manufactured by Nexperia USA Inc. and complies with JEDEC standards JESD8C for the 2.7 V to 3.6 V supply range.

Replacement Considerations

The 74LVT2241PW is a pin-compatible alternative housed in a TSSOP20 package. Other variants within the 74LVT2241 family may offer different package options but maintain identical electrical characteristics.
