74AHCT1G07GV,125

Buffers, Drivers, Receivers, Transceivers Overview

The NXP USA Inc. 74AHCT1G07GV,125 is a high-speed Si-gate CMOS non-inverting buffer with an open-drain output. 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 input switching levels and provides ESD protection exceeding 2000 V (HBM), 200 V (MM), and 1000 V (CDM). It is housed in a SC-74A (SOT753) plastic surface-mounted package with five leads.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Open-drain output configuration allows for active-LOW wired-OR or active-HIGH wired-AND logic functions when connected to other open-drain outputs.
• High noise immunity and low power dissipation characteristics inherent to the Si-gate CMOS technology.
• Robust electrostatic discharge protection capabilities across Human Body Model, Machine Model, and Charged Device Model standards.

Buffers, Drivers, Receivers, Transceivers Applications

• Implementing active-LOW wired-OR logic functions
• Implementing active-HIGH wired-AND logic functions
• General-purpose digital buffering applications requiring open-drain outputs

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the component matches the specific AHCT logic family requirements, as it differs electrically from the AHC variant regarding input thresholds and operating voltage. Confirm the SC-74A package designation aligns with PCB footprint constraints. Ensure the supplier source is authorized to guarantee authenticity, particularly given the corporate transition history involving Nexperia.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible input levels are required at 5 V operation. The open-drain architecture necessitates an external pull-up resistor to establish a logic HIGH level. Verify that the load capacitance and propagation delay specifications meet the system timing requirements under the intended operating voltage and temperature conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74AHC/AHCT1G0x series of single-gate logic buffers. It shares functional similarities with the 74AHC1G07 but utilizes TTL input switching levels suitable for 5 V systems. The GV suffix indicates the SC-74A (SOT753) surface-mount package option, distinguishing it from the GW TSSOP5 variant.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHC1G07GV,125 serves as a pin-compatible alternative within the same series, though it requires CMOS input levels and a wider voltage range. Other single-buffer open-drain devices in the 74LVC or 74HC families may be considered if electrical parameters such as drive current and speed are compatible.

Buffers, Drivers, Receivers, Transceivers FAQ

Why is a pull-up resistor required for this device?

Because the output is open-drain, it can only sink current to ground. An external pull-up resistor is necessary to provide the path for sourcing current and establishing a logic HIGH voltage level at the output.

What distinguishes the AHCT version from the AHC version?

The AHCT version features TTL input switching levels and is designed for a 4.5 V to 5.5 V supply range, whereas the AHC version uses CMOS input levels and operates from 2.0 V to 5.5 V.
