Product Information

Features

Qualified for Automotive Applications
ESD Protection Exceeds 2000 V Per MIL-STD-883, Method 3015; Exceeds 200 V Using Machine Model (C = 200 pF, R = 0)
Supports Mixed-Mode Signal Operation (5-V Input and Output Voltages With 3.3-V V_CC)
Supports Unregulated Battery Operation Down to 2.7 V
Typical V_OLP (Output Ground Bounce)
<0.8 V at V_CC = 3.3 V, T_A = 25°C
I_off Supports Partial-Power-Down Mode Operation
Bus-Hold Data Inputs Eliminate the Need for External Pullup Resistors

DESCRIPTION/ORDERING INFORMATION

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

The SN74LVT125-Q1 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.

This device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

To ensure the high-impedance state during power up or power down, OE should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
