1P1G126QYEPR

Overview

The SN74LVC1G126 is a single bus buffer gate with a 3-state output, designed for 1.65-V to 5.5-V VCC operation. It features a non-inverting logic function where the output is disabled when the OE input is low. The device supports 5-V VCC operation and inputs that accept voltages up to 5.5 V. It offers a maximum propagation delay of 3.7 ns at 3.3 V and provides ±24-mA output drive capability at 3.3 V. Power consumption is low, with a maximum ICC of 10 µA. The component includes Ioff circuitry to support partial-power-down mode, preventing damaging current backflow.

Feature Summary

• Supports 5-V VCC operation with inputs accepting voltages up to 5.5 V
• Features Ioff circuitry to enable partial-power-down mode operation
• Provides high-impedance state during power-up or power-down sequences

Applications

Procurement Notes

Verify the specific package type (YEP) and ordering suffix against the manufacturer's latest documentation before procurement. Confirm that the active status aligns with current design requirements. Ensure compatibility with the intended voltage levels and temperature ranges specified in the official datasheet. Cross-reference the part number with authorized distributors to validate authenticity and availability.

Selection Notes

Select this component for designs requiring a single-channel buffer with 3-state output capabilities within the 1.65-V to 5.5-V supply range. Consider the YEP package for space-constrained applications if compatible with the PCB layout. Evaluate the propagation delay and output drive strength against the system's timing and load requirements. Ensure the OE pin configuration supports the desired high-impedance behavior during power cycles.

FAQ

How does the device handle partial-power-down scenarios?

The device incorporates Ioff circuitry that disables the outputs when powered down, preventing damaging current backflow through the device.

What is the function of the OE input?

The output-enable (OE) input controls the 3-state output; when OE is low, the output is disabled, placing it in a high-impedance state.
