Overview
The MC74VHC1G126DF2G is a single-channel, non-inverting buffer and line driver from the VHC logic family. It operates within a supply voltage range of 3 V to 5.5 V. The device features three-state outputs with high-level output current of -8 mA and low-level output current of 8 mA. Static current is specified at 1 uA, while operating supply current is 40 uA. Power dissipation is rated at 200 mW. Propagation delay is 11.5 ns. It functions in temperatures from -55 C to +125 C.
Feature Summary
- Provides single-channel buffering with non-inverting logic functionality
- Features three-state outputs for bus-oriented applications
- Operates across a wide temperature range suitable for industrial environments
Applications
- Bus-oriented memory and signal switching
- Clock distribution and buffering
- High-speed data transmission lines
Procurement Notes
Verify the specific suffix DF2G against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for SC-70-5 packages. Cross-reference RoHS compliance status directly with the manufacturer's latest datasheet before procurement.
Selection Notes
Select this component when a single-channel, non-inverting buffer with three-state control is required. The VHC series offers CMOS performance with TTL-compatible inputs. Verify that the 3 V to 5.5 V supply range matches the system design requirements. Consider the SC-70-5 package size for space-constrained layouts.
Part Context
This part belongs to the MC74VHC1G series of single-gate buffers and drivers. It is designed for low-voltage applications requiring high speed and low power consumption. The VHC series is compatible with standard CMOS logic families while providing improved switching speeds compared to older HC series devices.
Replacement Considerations
Check for direct pin-to-pin replacements such as MC74VHC1GT126DF2G or MC74VHC1GT125DF2G if functional differences like gate count or inversion are acceptable. Verify electrical parameters match exactly before substitution.
