74HCT1G08GV,125

Overview

The Nexperia 74HCT1G08GV,125 is a single 2-input AND gate in the HCT logic family. 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 utilizes a SC-74A (SOT753) surface-mount package with five leads. Key electrical parameters include a maximum propagation delay of 27 ns at 4.5 V with a 50 pF load, input leakage current up to 1.0 μA, and supply current up to 20 μA.

Feature Summary

• Features TTL-compatible input levels for direct interfacing with standard digital logic systems.
• Includes internal clamp diodes on inputs to allow safe operation with voltages exceeding VCC when using current-limiting resistors.
• Provides high noise immunity and symmetrical output impedance characteristics.

Applications

• General-purpose digital logic signal processing
• Interface circuits requiring TTL-to-CMOS level translation
• Embedded system control logic

Procurement Notes

Verify that the component matches the specific HCT logic family requirements, as HC variants differ in input thresholds. Confirm the SC-74A package designation corresponds to SOT753. Ensure the operating environment stays within the specified -40 °C to +125 °C range. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this part when TTL-level compatibility is necessary for inputs while maintaining CMOS low power dissipation. The SC-74A package is suitable for space-constrained surface-mount designs. Consider the 27 ns propagation delay limit for timing-critical applications. Verify that the 4.5 V to 5.5 V supply range aligns with the target system voltage.

Part Context

This component belongs to the Nexperia 74HCT1G08 series, which includes variants in TSSOP5 and XSON5 packages. The 'GV' suffix indicates the SC-74A package type, while '125' denotes the tape and reel packaging format. It is part of the broader 74HC/HCT single-gate portfolio designed for compact digital logic implementations.

Replacement Considerations

The 74HC1G08GV,125 serves as a functional alternative but requires verification of input voltage threshold compatibility, as it uses CMOS levels rather than TTL levels.
