General Description

/ordering information This bus buffer is designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

The SN74LVTH125

Overview

D Controlled Baseline − One Assembly/Test Site, One Fabrication Site D Enhanced Diminishing Manufacturing Sources (DMS) Support D Enhanced Product-Change Notification D Qualification Pedigree† D Supports Mixed-Mode Signal Operation (5-V Input and Output Voltages With 3.3-V VCC) D Supports Unregulated Battery Operation Down to 2.7 V D Typical VOLP (Output Ground Bounce) <0.8 V at VCC = 3.3 V, TA = 25°C † Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range.

This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life.

Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits.

Key Features

  • independent line drivers with 3-state outputs. Each output is in the high-impedance state when the associated output-enable (OE) input is high. Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended. When VCC is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5 V, OE should be tied to VCC th.
