74LVT162240MTDX

Overview

The onsemi 74LVT162240MTDX is a low-voltage 16-bit inverting buffer and line driver featuring 3-STATE outputs with integrated 25Ω series resistors. It operates within a supply voltage range of 2.7V to 3.6V, supporting input voltages up to 5.5V for TTL interface compatibility. The device utilizes advanced BiCMOS technology to achieve high-speed operation with propagation delays as low as 1.0ns at 3.3V. It includes bushhold data inputs to eliminate external pull-up requirements and offers power-up/down high impedance for glitch-free bus loading.

Feature Summary

• Integrated 25Ω series resistance in output drivers reduces overshoot and undershoot without requiring external termination components
• Bushold data inputs maintain logic states for unused pins, removing the need for external pull-up resistors
• Nibble-controlled architecture allows independent or combined 16-bit operation via Output Enable inputs
• Power-up/down high impedance state ensures glitch-free bus loading during system initialization

Applications

• Memory address drivers
• Clock signal distribution
• Bus-oriented transmitter/receiver circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Ensure design compliance with absolute maximum ratings to prevent device damage. Cross-reference datasheet specifications against current revisions to validate electrical parameters before final integration.

Selection Notes

Select this component when designing systems requiring 3.3V logic interfacing with 5V environments. The integrated series resistance simplifies PCB layout by reducing EMI and eliminating external termination resistors. Verify that the TSSOP-48 package fits the available board space and thermal constraints. Consider the bushhold feature if minimizing external passive components is a priority.

Part Context

This device belongs to the LVT logic family, designed for low-power applications while maintaining performance comparable to older 5V ABT series devices. Originally manufactured by Fairchild Semiconductor, the product line continues under onsemi. The MTDX suffix indicates the Thin Shrink Small Outline Package (TSSOP) configuration with tape and reel packaging for automated assembly.

Replacement Considerations

The 74LVTH162240MTDX serves as a functional equivalent with identical pinout and electrical characteristics. Both variants share the same TSSOP-48 package and nibble control scheme. Verify that the replacement part number matches the specific ordering code required for tape and reel availability.
