74LVT2241D,118

Overview

The Nexperia 74LVT2241D,118 is a BiCMOS 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 provides an output drive capability of +12 mA and -12 mA. Propagation delays are specified with maximum values of 5.0 ns for low-to-high transitions and 4.7 ns for high-to-low transitions at 2.7 V. At 3.3 V, these delays reduce to maximums of 4.2 ns and 4.3 ns respectively. The component includes bus hold inputs to eliminate external pull-up resistors and IOFF circuitry for partial power-down operation.

Feature Summary

• Integrated series termination resistors in each output path remove the requirement for external termination components.
• Bus hold data inputs maintain defined logic states for unused pins without requiring external pull-up resistors.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow currents from powered buses.
• Inputs tolerate voltages up to 5.5 V, allowing direct interfacing with 5 V systems while operating at lower supply voltages.

Applications

• Octal bus interface buffering
• Line driving applications
• Mixed 3.3 V and 5 V system interconnects

Procurement Notes

Verify the specific ordering suffix matches the required package type. The 'D' suffix indicates an SO20 plastic small outline package (SOT163-1). Confirm that the temperature range and lead-free status align with project specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring an 8-bit buffer with integrated series termination. It is suitable for applications needing direct TTL level interfacing and overvoltage tolerant inputs. Ensure the design accommodates the 2.7 V to 3.6 V supply voltage range and utilizes the bus hold feature to simplify input handling.

Part Context

This part belongs to the 74LVT logic family, designed for low-voltage CMOS applications. It serves as an octal buffer/line driver variant within Nexperia's standard logic portfolio. The device is manufactured using BiCMOS technology to achieve high speed and robust output drive capabilities suitable for demanding bus interface environments.

Replacement Considerations

The 74LVT2241PW is a functional equivalent utilizing a TSSOP20 package (SOT360-1) instead of the SO20 package found in the D variant. Verify pin compatibility and thermal requirements when substituting between these package types.
