74AHCT1G126GV,125

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT1G126GV,125 is a single bus buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level inputs. The device utilizes the SC-74A (SOT753) surface-mount package with five leads. It provides symmetrical output impedance and balanced propagation delays, ensuring reliable signal transmission in mixed-voltage environments due to overvoltage tolerant inputs.

• Provides non-inverting buffering with three-state output control via an enable input
• Features overvoltage tolerant inputs allowing operation as a translator in mixed-voltage systems
• Accepts TTL logic levels for compatibility with standard digital interfaces
• Offers high noise immunity and low CMOS power dissipation characteristics

Buffers, Drivers, Receivers, Transceivers Applications

• Signal buffering on system buses
• Line driving for communication interfaces
• Voltage translation between different logic domains
• Isolating components in mixed-voltage circuit designs

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix matches the required SC-74A package configuration. Confirm the AHCT designation aligns with TTL input requirements rather than CMOS levels. Ensure environmental compliance standards meet project specifications before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible input thresholds are necessary alongside three-state bus isolation capabilities. The SC-74A package offers a compact footprint suitable for space-constrained printed circuit board layouts. Verify that the operating voltage remains within the specified 4.5 V to 5.5 V range for optimal performance.

Buffers, Drivers, Receivers, Transceivers Part Context
