74LVT162245MTDX

Overview

The 74LVT162245MTDX is a 3.3-V ABT 16-bit buffer/driver with 3-state outputs manufactured by onsemi. It features bus-hold data inputs to eliminate external pull-up resistors and supports live insertion/extraction. The device provides power-up/down high-impedance for glitch-free bus loading. A Port outputs include equivalent series resistance of 25Ω, reducing overshoot and undershoot without external termination. Latch-up performance exceeds 500 mA, and ESD protection meets HBM > 2000V, MM > 200V, and CDM > 1000V standards.

Feature Summary

• Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs
• A Port outputs include equivalent series resistance making external termination resistors unnecessary
• Power Up/Down high impedance provides glitch-free bus loading
• Live insertion/extraction permitted

Applications

• High-speed data bus buffering
• System interface at 5V VCC
• Live insertion applications

Procurement Notes

Verify the manufacturer designation carefully, as this component was originally developed by Fairchild Semiconductor and is now part of onsemi's portfolio after acquisition. Confirm the specific suffix MTDX corresponds to the required tape and reel packaging format for your assembly line. Ensure the datasheet version matches the current revision to validate electrical characteristics and pinout compatibility before finalizing procurement orders.

Selection Notes

Select this component when interfacing between systems operating at different voltage levels, specifically supporting 3.3-V logic with 5-V system interfaces. The integrated 25Ω series resistance in the A Port outputs simplifies design by removing the need for external termination resistors. Choose this device for applications requiring robust ESD protection and latch-up immunity exceeding standard industry limits.

Part Context

This component belongs to the 74LVT (Low Voltage TTL) family of logic integrated circuits. It functions as an octal bus transceiver designed for high-speed data transfer. The device is characterized for operation over a temperature range of -40°C to +85°C. It is housed in a TSSOP-48 package, suitable for surface-mount technology applications requiring compact footprint and high pin density.

Replacement Considerations

The 74LVTH162245 is functionally compatible but lacks the bus-hold feature found in the 74LVT162245. Verify if external pull-up resistors are required if substituting with non-bus-hold variants. Check pinout compatibility across different manufacturers such as Texas Instruments or NXP to ensure direct replacement feasibility without schematic modifications.
