74LVT162240ADL,112

Overview

The Nexperia USA Inc. 74LVT162240ADL,112 is a high-performance BiCMOS inverting 16-bit buffer/driver designed for VCC operation at 3.3 V. It features four output enable pins (1OE, 2OE, 3OE, 4OE), each controlling four of the 3-state outputs. The device includes 30 Ω series resistance in both pull-up and pull-down output structures to reduce line noise. It supports TTL input and output switching levels and interfaces with systems at 5 V supply. Bus-hold data inputs eliminate external pull-up resistors. Specified from -40 °C to +85 °C.

Feature Summary

• Inverting 16-bit bus interface with 3-state buffers
• Integrated 30 Ω series termination resistors in output structures
• Bus-hold data inputs to hold unused inputs without external components
• Power-up 3-state and no bus current loading when tied to 5 V bus

Applications

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

Procurement Notes

Verify the specific package variant against the datasheet revision history. The ADL suffix corresponds to the SSOP48 package (SOT370-1), which was removed from the product data sheet in version 4 released on June 4, 2018. Confirm availability and current manufacturing status directly with Nexperia or authorized distributors, as this specific ordering suffix may be obsolete or superseded by other package options like the DGG (TSSOP48).

Selection Notes

Select this component for applications requiring a 3.3 V inverting buffer with integrated termination to minimize signal reflections. Ensure the design accommodates the 30 Ω internal series resistance. Verify that the 5 V tolerant inputs and outputs meet the system voltage requirements. Check if the SSOP48 package is still supported or if an alternative package like TSSOP48 is required for the PCB layout.

Part Context

The 74LVT162240A belongs to the LVT logic family, optimized for 3.3 V operation. It is part of a range of 16-bit bus interface devices offering various configurations such as non-inverting buffers and transceivers. The device utilizes BiCMOS technology to provide high speed and output drive capabilities while maintaining low power consumption.
