Description

74VHC125MTCX is a high-speed CMOS quad buffer with tri-state outputs. It contains four noninverting buffers (A1→Y1, A2→Y2, A3→Y3, A4→Y4) with independent output-enable controls. Each buffer outputs the input when its OE pin is driven low; when OE is high, the output is high-impedance. It operates on a single supply from about 2.0 to 5.5 V (typically 5 V) with TTL-compatible input thresholds and fast propagation. Applications include buffering signals, driving buses, level shifting between devices, and isolating circuit portions. The MTCX suffix denotes the manufacturer’s packaging/delivery option (check the datasheet for exact package type, temperature grade, and mechanical details). For precise drive strength, leakage, and timing specs, consult the datasheet.

Features

Key features of 74VHC125MTCX (quad buffer with 3-state outputs):
- Quad non-inverting buffers with four independent outputs
- Independent output-enable inputs (OE) for each buffer; OE is active-low
- 3-state outputs to share buses
- Wide supply range: Vcc = 2 V to 6 V
- Ioff protection for partial-power-down and back-powering protection
- High-speed CMOS with low static power
- Interfaces well with both CMOS and TTL logic levels (CMOS thresholds)
- Packaged in MTCX (14-pin) format
Concise summary: four buffers, tri-state control, wide Vcc, Ioff, high-speed CMOS, compatible with diverse logic levels.

Package

14-pin package: TI’s MTCX suffix denotes the TSSOP-14 (Thin Shrink Small‑Outline) RoHS package.

Pinout

- Pin count: 14 pins (14-pin package, e.g., SOIC/TSSOP as in MTCX version).
- Function: Quad 3-state noninverting buffer/line driver. Four independent buffers with inputs A1–A4, outputs Y1–Y4, and separate active-low enable inputs (OE1–OE4). When the corresponding OE is low, Y follows A; when OE is high, the output is high-impedance.

Manufacturer

Manufacturer: Nexperia (formerly part of Philips/NXP).
What kind of company: A global semiconductor company that designs and manufactures discrete and logic integrated circuits (e.g., buffers/gates, protection devices, MOSFETs) for automotive, industrial, consumer, and other markets.

Application

74VHC125MTCX is a quad buffer/line driver with tri-state outputs. Applications:
- Buffering and isolating data/address buses between a CPU/microcontroller and memory or peripherals
- Level shifting between voltage domains (e.g., 5V ↔ 3.3V)
- Bus multiplexing/demultiplexing and preventing bus contention
- Clock or enable signal distribution and fan-out to multiple devices
- General-purpose buffering for interfacing peripherals, memory, LCDs, and ADC/DACs

Equivalent

Equivalents (quad buffer with 3-state outputs at 5V):
- SN74VHC125 (Texas Instruments)
- 74VHC125 (Nexperia, STMicroelectronics, ON Semiconductor – vendor variants)
- 74HC125 (older HC family, same function)
- 74HCT125 (TTL-input thresholds; use if TTL compatibility is needed)
Note: choose based on voltage/threshold requirements and pinout/footprint compatibility.
