74LVT162240MTD

Overview

The onsemi 74LVT162240MTD is a low-voltage 16-bit inverting buffer and line driver featuring 3-STATE outputs. It incorporates equivalent series resistance of 25 ohms in both HIGH and LOW output states to reduce overshoot, undershoot, and line noise without requiring external termination resistors. Designed for 3.3V VCC applications, it provides TTL interface capability to 5V environments. The device utilizes advanced BiCMOS technology for high-speed operation with low power dissipation. It supports live insertion/extraction and offers glitch-free bus loading during power-up/down events.

Feature Summary

• Integrated 25 ohm series resistance in outputs eliminates the need for external termination resistors and reduces signal reflections.
• Provides 3-STATE outputs controlled by four independent Output Enable inputs, allowing nibble-level or full 16-bit operation.
• Supports live insertion and extraction while maintaining glitch-free bus loading during power transitions.

Applications

• Memory address drivers
• Clock drivers
• Bus oriented transmitter/receiver circuits

Procurement Notes

Verify that the specific ordering code matches the required package variant, as the MTD suffix denotes the 48-lead Thin Shrink Small Outline Package (TSSOP). Confirm whether the bushhold feature is necessary for the design; if so, ensure the LVTH variant is selected instead of the standard LVT version. Check datasheet specifications for absolute maximum ratings to ensure system voltages remain within safe operating limits.

Selection Notes

Select this component when designing systems requiring 16-bit data buffering with integrated series resistance to minimize EMI and signal integrity issues. It is suitable for interfaces between 3.3V logic and 5V tolerant environments. Consider the LVTH variant if input bushold functionality is required to manage unused inputs without external pull-up resistors. Ensure the TSSOP-48 package fits the PCB layout constraints.

Part Context

This device belongs to the 74LVT family of low-voltage CMOS logic devices. It is functionally compatible with the older 74 series 162240 but operates at lower supply voltages. The part is manufactured using BiCMOS technology to achieve performance levels similar to 5V ABT logic families while maintaining reduced power consumption typical of low-voltage standards.

Replacement Considerations

The 74LVTH162240MTD is a functional alternative that includes bushhold inputs. Other variants in the same family include SSOP packages (MEA suffix) and tape-and-reel options (X suffix). Verify pin compatibility and electrical characteristics before substituting.
