74LVC1G17FZ4-7

Overview

The 74LVC1G17FZ4-7 is a single-input Schmitt-trigger buffer manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.65V to 5.5V and features a standard push-pull output capable of ±24mA drive at 3.3V. The device includes IOFF circuitry for partial power-down applications, preventing damaging backflow current when powered down. Inputs are tolerant to 5.5V, enabling use in mixed-voltage environments. It is packaged in an X2-DFN1410-6 format.

Feature Summary

• Single-channel non-inverting buffer with Schmitt-trigger input characteristics
• Integrated IOFF circuitry supports partial power-down mode operation
• Input tolerance up to 5.5V allows compatibility in mixed-voltage systems
• Standard push-pull output configuration

Applications

• Voltage level shifting between different logic domains
• General purpose logic signal buffering
• Power down signal isolation in electronic circuits

Procurement Notes

Verify the specific package marking code UR corresponds to the X2-DFN1410-6 footprint on the PCB. Confirm that the design accommodates the recommended pad layout dimensions provided in the datasheet to ensure reliable soldering. Ensure input pins are tied to VCC or Ground if unused to prevent floating states.

Selection Notes

Select this component when noise immunity is required due to its Schmitt-trigger inputs. It is suitable for designs requiring protection against backflow currents during power-down sequences. Verify that the operating temperature range of -40°C to +125°C meets the environmental requirements of the target application.

Part Context

This part belongs to the 74LVC1G17 series of single Schmitt-trigger buffers from Diodes Incorporated. The FZ4 suffix specifically denotes the X2-DFN1410-6 package type. The series is designed for low-power CMOS applications across a wide voltage spectrum.

Replacement Considerations

Direct pin-to-pin replacements may include other manufacturers' equivalents such as the SN74LVC1G17YZPR from Texas Instruments, provided electrical parameters and package dimensions are verified against the original specifications.

FAQ

What is the function of the IOFF circuitry?

The IOFF circuitry disables the output to prevent damaging current backflow when the device is in a partial power-down state.

Can this device interface with 5.5V logic signals?

Yes, the inputs are tolerant to 5.5V, allowing the device to be used in mixed-voltage environments.
