74LCXAWM is a low-voltage CMOS logic IC that features six inverter channels with Schmitt trigger inputs. It is designed for high-speed and low-power applications that require 5 V tolerant inputs. In this article, we will explain what 74LCXAWM is, how it works, and how to use it in your projects.
What is 74LCXAWM
74LCXAWM is a part of the 74LCX family of logic ICs manufactured by onsemi. It is a surface-mount device that comes in a 14-pin SOIC package. The pinout and function of 74LCXAWM are shown below:
As you can see, 74LCXAWM has six independent inverter channels, each with one input (A) and one output (Y). The inputs are Schmitt trigger type, which means they have hysteresis and can reject noise and slow input transitions. The outputs are capable of driving up to 24 mA of current at 3.3 V supply voltage.
74LCXAWM operates from a supply voltage range of 2 V to 3.6 V, but it can accept inputs up to 7 V, making it compatible with 5 V logic signals. It also has power-down protection on inputs and outputs, which prevents damage from excess voltage when the device is powered off.
The main advantages of 74LCXAWM are its high speed, low power consumption, and wide input voltage range. It has a maximum propagation delay of 6.5 ns at 3.3 V and 50 pF load capacitance, and a maximum quiescent current of 10 ÂµA at 25 ÂC. It is suitable for interfacing with various logic families, such as TTL, CMOS, LVTTL, LVCMOS, GTL, BTL, etc.
How to Use 74LCXAWM
74LCXAWM can be used for various logic functions that require inversion, such as buffers, drivers, oscillators, waveform generators, etc. Here are some examples of how to use 74LCXAWM in your circuits:
Buffer: You can use a single channel of 74LCXAWM as a buffer to isolate a logic signal from its load or source. This can help prevent signal degradation or interference caused by long wires, high capacitance, or low impedance. For example, you can use a buffer to connect a microcontroller output to an LED or a relay.
Driver: You can use multiple channels of 74LCXAWM in parallel to increase the output current and drive heavier loads. For example, you can use four channels to drive a seven-segment display or a speaker.
Oscillator: You can use two channels of 74LCXAWM in a feedback loop to create an oscillator circuit that generates a square wave signal. By adding a resistor and a capacitor to the loop, you can adjust the frequency and duty cycle of the output wave. For example, you can use an oscillator to generate a clock signal for another logic device or a tone for a buzzer.
Waveform Generator: You can use four channels of 74LCXAWM in a ring configuration to create a waveform generator circuit that produces four different phases of square waves. By adding resistors and capacitors to each channel, you can modify the shape and amplitude of each wave. For example, you can use a waveform generator to create PWM signals for motor control or LED dimming.
