74LVT162240ADL,118

Overview

The Nexperia 74LVT162240ADL,118 is a BiCMOS inverting buffer/driver designed for 3.3 V operation. It features 16-bit bus interface capability with four independent 3-state output enable pins (1OE, 2OE, 3OE, 4OE). The device incorporates internal 30 Ω series termination resistors to reduce line noise. Recommended operating conditions specify a supply voltage range of 2.7 V to 3.6 V and an ambient temperature range of -40 °C to +85 °C. Propagation delays are typically 2.6 ns at 3.3 V.

Feature Summary

• Integrated 30 Ω series resistance in pull-up and pull-down structures eliminates the need for external termination resistors.
• Bus-hold data inputs maintain unused input states without requiring external pull-up resistors.
• Four separate output enable pins allow granular control over groups of four outputs each.
• Supports live insertion and extraction while preventing bus current loading when tied to a 5 V bus.

Applications

• Memory address drivers
• Clock drivers
• Bus receivers and transmitters

Procurement Notes

Verify the package type matches the design requirements, as the datasheet revision history indicates that the SSOP48 version was removed. Confirm the specific ordering suffix corresponds to the TSSOP48 package variant currently listed in the official ordering information table. Ensure compliance with the specified temperature range for the intended application environment.

Selection Notes

Select this component for applications requiring high-speed signal inversion with integrated impedance matching. The inclusion of bus-hold functionality simplifies PCB layout by removing the need for discrete pull-up components. Verify that the 12 mA output drive capability meets the load requirements of the destination circuitry within the specified voltage range.

Part Context

This device belongs to the 74LVT162240A family of 3.3 V logic buffers. It utilizes BiCMOS technology to achieve high performance and low power consumption. The product is specified in compliance with JEDEC standards for latch-up protection and ESD tolerance, ensuring reliability in industrial environments.

Replacement Considerations

The datasheet revision history notes that the 74LVT162240ADL (SSOP48) part number has been removed from the product lineup. Designers must transition to the available TSSOP48 package variant or equivalent functional replacements if the original package is no longer supported.

FAQ

How does the device handle unused inputs?

The device features bus-hold data inputs which eliminate the need for external pull-up resistors to hold unused inputs in a defined state.

What is the function of the internal 30 Ω resistors?

The internal 30 Ω series resistance reduces line noise in applications such as memory address drivers and clock drivers, making external termination resistors unnecessary.
