MC74VHC1G126DFT1G

Buffers, Drivers, Receivers, Transceivers Overview

The MC74VHC1G126DFT1G is a single-channel non-inverting 3-state buffer from the VHC logic family, manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 5.5 V and features CMOS-level input thresholds. The device provides high noise immunity through a buffered three-stage internal circuit and includes over-voltage tolerant inputs and outputs up to 5.5 V. It supports partial power down protection via IOFF and offers source/sink currents of 8 mA at 3.0 V. Packaged in SC-88A (SOT-353), it ensures stable signal transmission with propagation delays as low as 3.5 ns at 5 V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DFT1G' corresponds to the SC-88A package and tape & reel shipping configuration. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the design accounts for the maximum operating temperature range of -55°C to +125°C if used in harsh environments.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this part when a single-channel non-inverting buffer with 3-state control is required. It is suitable for applications needing CMOS-level threshold compatibility rather than TTL levels. Consider the SC-88A footprint constraints and verify that the 8 mA drive current meets the load requirements of the destination circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the MC74VHC1G126 series, which includes variants like the MC74VHC1GT126 featuring TTL-level inputs. The series is designed for low-power, high-speed digital applications. Other packages in the family include SC-74A, SOT-953, and UDFN6, offering flexibility for different board space requirements while maintaining identical electrical characteristics.
