74HCT2G125DP,125

Overview

The Nexperia 74HCT2G125DP,125 is a dual buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes TTL input switching levels. The device provides non-inverting logic functions with high noise immunity and low power dissipation characteristics typical of CMOS technology. It is housed in an SOT505-2 TSSOP8 package with eight leads. The component supports an ambient operating temperature range from -40 °C to +125 °C and includes input clamp diodes for interfacing with voltages exceeding VCC.

Feature Summary

• Features three-state outputs controlled by active-low enable inputs for bus-oriented applications
• Utilizes TTL-compatible input switching levels for direct interface with standard logic families
• Includes input clamp diodes allowing current limiting resistors for voltages exceeding VCC
• Provides high noise immunity and low power dissipation inherent to Si-gate CMOS construction

Applications

• Bus-oriented memory and data transmission systems
• Driving capacitive or resistive loads on communication lines
• Interface circuits requiring signal buffering between different logic domains
• Clock distribution networks requiring controlled output states

Selection Notes

Select this component when TTL-level compatibility is required alongside three-state bus control capabilities. Ensure the design environment accommodates the specified 4.5 V to 5.5 V supply voltage range. Consider the TSSOP8 package dimensions for PCB layout constraints. Verify that the application does not exceed the absolute maximum ratings for input clamping currents or total power dissipation derating curves provided in the datasheet.

Part Context

This part belongs to the Nexperia 74HCT series of high-speed silicon-gate CMOS logic devices. It is functionally compatible with other industry-standard 74HCT logic families but offers a compact dual-channel configuration in a small outline package. The DP variant specifically denotes the TSSOP8 plastic thin shrink small outline package version, distinguishing it from other package options like VSSOP8 available within the same logical family.

Replacement Considerations

Direct replacements include the 74HC2G125DP,125 for CMOS input level requirements, or other 74HCT2G125 variants from different manufacturers adhering to JEDEC standards. Ensure pinout compatibility and verify that substitute components meet the same electrical specifications for propagation delay and output drive capability.
