74LVT2241PW,118

Overview

The Nexperia 74LVT2241PW,118 is an octal buffer and line driver featuring 3-state outputs housed in a TSSOP20 package. It operates within a supply voltage range of 2.7 V to 3.6 V. The device provides output drive capabilities 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 integrated series termination resistors.

Feature Summary

• Integrated 30 Ω series termination resistors eliminate the need for external components.
• Bus hold data inputs maintain unused input states without requiring external pull-up resistors.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent backflow current.
• Overvoltage tolerant inputs allow direct interfacing with systems operating at 5 V supply levels.

Applications

• Octal bus interface applications
• Systems requiring live insertion and extraction
• Interfacing between 3.3 V logic and 5 V system buses

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm the temperature range aligns with operational requirements, noting this variant is rated for -40 °C to +85 °C. Ensure design compliance with JEDEC standards JESD8C for the specified voltage range. Check for any recent datasheet revisions that may impact pinning or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring an octal buffer with built-in series termination to simplify layout. It is suitable for applications needing direct TTL level interfacing and overvoltage tolerance up to 5.5 V on inputs. Consider the TSSOP20 package constraints regarding body width and lead pitch. Verify that the 3-state control logic matches the system's enable requirements for both active LOW and active HIGH configurations.

Part Context

This device belongs to the 74LVT logic family, designed for low-voltage CMOS applications. It serves as a high-speed buffer solution within Nexperia's portfolio of logic ICs. The PW suffix specifically denotes the TSSOP20 plastic thin shrink small outline package variant, distinguishing it from other physical form factors available under the same logical specification.

Replacement Considerations

The 74LVT2241D is a functional equivalent utilizing an SO20 package instead of TSSOP20. Both share identical electrical specifications and pinouts. Designers must verify mechanical footprint compatibility when substituting between these package types.

FAQ

How does the bus hold feature function?

The bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs, maintaining their state internally.

What is the purpose of the IOFF circuitry?

The IOFF circuitry provides partial power-down mode operation by disabling the output, preventing damaging backflow current through the device when it is powered down.

Can this device interface directly with 5 V systems?

Yes, the inputs are overvoltage tolerant to 5.5 V, allowing direct interface capability to systems at 5 V supply.
