Overview
The MC74VHCT126ADT is a single non-inverting buffer and line driver from the 74VHCT logic family, manufactured by onsemi. It operates within a supply voltage range of 4.5 V to 5.5 V and features a TSSOP-14 surface-mount package. The device provides high-speed operation with low power dissipation, maintaining compatibility with standard TTL input levels while offering CMOS output characteristics. It includes three-state outputs controlled by an enable input, designed for efficient signal buffering in digital systems.
Feature Summary
- Single-channel non-inverting buffer configuration
- TTL-compatible input thresholds for reliable interfacing
- Three-state output control for bus isolation
- High noise immunity with low power consumption
Applications
- Memory address drivers
- Clock distribution circuits
- Bus-oriented system architectures
Procurement Notes
Verify the exact suffix against official datasheets to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your specific manufacturing process. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity before procurement.
Selection Notes
Select this component when a single-channel buffer with TTL-compatible inputs is required within a 5V logic environment. It is suitable for applications needing high-speed signal transmission with minimal power usage. Consider the VHCT series for improved noise immunity compared to standard HC or HCT families in noisy environments.
Part Context
This part belongs to the 74VHCT series, which combines the speed of VHCT technology with TTL-compatible inputs. It is part of a broader family of buffers and line drivers designed for high-performance digital applications. The single-buffer configuration offers space savings compared to quad-buffer alternatives in compact designs.
Replacement Considerations
Direct substitutes include other single non-inverting buffers with three-state outputs and TTL-compatible inputs from the same or compatible logic families. Verify pinout compatibility and electrical specifications such as propagation delay and output drive current before substitution.
