74HCT1G126GV,125

Overview

The Nexperia 74HCT1G126GV,125 is a single non-inverting 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 utilizes TTL input switching levels. The device is housed in an SC-74A (SOT753) surface-mount package with five leads. It supports an ambient operating temperature range from -40 °C to +125 °C.

Feature Summary

• Provides one non-inverting buffer/line driver with three-state output controlled by the OE pin.
• Features inputs with clamp diodes for interfacing to voltages exceeding VCC using current limiting resistors.
• Offers high noise immunity and balanced propagation delays.

Applications

• Bus-oriented transmissions
• Clock distribution
• Timing control

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Confirm that the required temperature grade matches the standard industrial rating specified in the product data sheet before finalizing procurement orders.

Selection Notes

Select this component when a single-channel buffer with three-state capability is required for TTL-level logic systems. Ensure the design environment maintains the recommended 4.5 V to 5.5 V supply voltage range. Verify that the thermal dissipation requirements are met within the specified -40 °C to +125 °C operating temperature limits.

Part Context

This part belongs to the Nexperia 74HCT1G series of single-gate logic devices. It is designed as a compact solution for signal buffering in space-constrained applications. The HCT designation indicates compatibility with standard TTL logic families while utilizing CMOS technology for low power consumption.

Replacement Considerations

The 74HC1G126GV,125 serves as a functional equivalent but requires CMOS-compatible input levels rather than TTL levels. Other single-buffer variants within the same family may offer different speed or voltage characteristics.
