Overview
Description
74VHC125MTCX is a quad buffer/line driver with 3-state (tri-state) outputs in a small package (MTCX variant). Key points:
- Four independent buffer channels: each with an input (A), an output (Y), and an output-enable input (OE).
- When OE is active (low for 125 devices), Y follows A; when OE is inactive (high), Y is high-impedance.
- Very High Speed CMOS (VHC) family: operates from a supply range of about 2 V to 6 V (commonly 3.3 V or 5 V).
- TTL/CMOS input compatible, low static power, fast switching.
- Used for buffering signals between different logic sections or for bus isolation/drive-strength enhancement.
- Packaging: MTCX denotes a specific small-outline package variant (generally 14-pin).
If you need exact pinout and OE polarity for your exact package, consult the datasheet for the 74VHC125MTCX variant from the manufacturer.
