概述

Description

The 74LCX32MTCX is a quad 2-input OR gate in the 74LCX low‑voltage CMOS family. It contains four independent OR gates (A1 OR B1 → Y1, A2 OR B2 → Y2, etc.) in a single package. It operates from a single supply in the low‑voltage range (typical about 2.0–3.6 V; check the specific vendor’s datasheet). Features include low static power, fast switching, and good noise margins, making it suitable for portable or battery-powered digital logic. The MTCX suffix identifies a specific small-outline package (likely a 14-pin surface-mount package) used for this device. Applications include simple OR logic, signal routing, clock gating, and other digital logic tasks. For exact electrical characteristics (propagation delay, input/output levels, maximum ratings) and package details, refer to the datasheet from the manufacturer, as values can vary slightly between vendors.

Features

74LCX32MTCX features:
- Quad 2-input OR gates (four independent OR functions)
- CMOS low-voltage operation
- Supply voltage: 2.0 V to 3.6 V
- Bus-hold on all inputs (reduces need for external pull-ups)
- Ioff support for partial-power-down (no back-powering when Vcc is 0)
- High noise immunity with standard CMOS input thresholds
- Low static and dynamic power consumption
- Wide operating temperature range: -40°C to 125°C
- 14-pin MTCX surface-mount package

Package

14-pin TSSOP (Thin Shrink Small-Outline Package). The MTCX suffix is TI’s code for that 14‑pin TSSOP package.

Pinout

- Pin count: 14 pins
- Function: Quad 2-input OR gate (four independent OR gates: Y1 = A1 OR B1, Y2 = A2 OR B2, Y3 = A3 OR B3, Y4 = A4 OR B4) in the 74LCX32 family.

Manufacturer

Manufacturer: Nexperia (formerly Philips/NXP). Nexperia is a global semiconductor company that designs and manufactures discrete components and logic ICs (including 74-series parts) and MOSFETs for electronics applications.

Application

- General-purpose quad 2-input OR gate for digital logic
- OR-ing multiple control or status signals
- Fan-in for microcontroller interfaces and bus lines
- Enable/wake-up gating and simple power-on/reset logic
- Signal routing and data/path merging in low-voltage CMOS systems
- Bus arbitration and basic clock/data gating in 2–3 V logic environments

Equivalent

Equivalent devices: quad 2-input OR gates in similar CMOS families. Examples include:
- TI: SN74HC32, SN74HCT32, SN74LVC32, SN74LVX32, SN74ACT32
- NXP/ST/Onsemi: 74HC32, 74LVC32, 74VHC32
Check exact pinout and supply: 1.65–3.6V (LV/LX variants) vs 4.5–5.5V (HCT/ACT). Ensure MTCX package compatibility or adapt to your footprint.
