74HCT3G34GD,125

Overview

The 74HCT3G34GD,125 is a triple buffer gate manufactured by Nexperia. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL-level input compatibility and CMOS low power dissipation. It includes input clamp diodes for interfacing with voltages exceeding VCC. The component provides high noise immunity and robust latch-up performance exceeding 100 mA per JESD 78 Class II Level B.

Feature Summary

• Triple non-inverting buffer configuration
• TTL-compatible input levels
• High noise immunity and low power consumption

Applications

• General-purpose buffering in digital logic circuits
• Signal line driving applications
• Interface level translation between TTL and CMOS domains

Procurement Notes

Verify the specific package type associated with the GD suffix against current manufacturer documentation, as revision history indicates changes to available packages. Confirm availability status directly with authorized distributors, as older XSON variants may have been superseded or discontinued in favor of TSSOP or VSSOP options.

Selection Notes

Select this component when TTL-level inputs are required at 5V operation. Ensure the design accommodates the specified propagation delay and transition times under the target load capacitance. Verify that the operating temperature range meets the environmental requirements of the final application.

Part Context

This part belongs to the 74HCT3G34 family of triple buffer gates. The datasheet revision history notes that the GD variant (XSON8) was removed in version 7, suggesting it has been superseded by other package types such as TSSOP8 or VSSOP8 within the same logical family.

Replacement Considerations

Public confirmed substitute part numbers: 74HC3G34DP,125; 74HCT3G34DC,125.
