74ls32 pinout

74LS32 is a Dual Input OR Gate with Quad package

 

It contains four independent gates, each performing the logic OR function. Each gate has two inputs, which is why it is called Quad 2-Input OR Gate. Logic level gates like 74LS32 and flip-flops play a vital role in digital electronics.

 

This blog is a brief introduction to 74LS32 about its pinout, features, equivalents, and how to use this device and so on.

 

This is a video introducing 74LS32's truth table.

How to Use 74LS32 OR Gate IC?

74LS32 or 74LS32N has 12 input output pins for a total of four OR gates. To use the 74LS32 Logic gate IC, just power it with the Vcc and ground pins. The typical operating voltage of the IC is +5V, but it can also be operated in +7V. The output voltage of the IC on the pin Y is equal to the operating voltage of the IC. As per the OR gate truth table, if either one or both of the gate inputs are high, the output will be high. The truth table of OR gate is given below:

OR Gate Truth Table

 

According to the truth table, when both the inputs are low, output will be zero.

When either one or both the input of the Gate is high, the output will be high.

FAQ

  • What is 74ls32?

The 74LS32 is a Dual Input OR Gate with Quad package. It contains four independent gates each of which performs the logic OR function. Each gate has two inputs that’s why it is named Quad 2-Input OR Gate. Logic level gates like 74LS32 and flip-flops play a vital role in digital electronics.

  • What is the difference between 74ls32 and 74ls32n?

74LS32N and 74LS32 have the same performance and function, both are 2-input four-OR gates. 74LS32 omits the description of the package form of the device. The package form of 74LS32N is plastic dual in-line.

  • What is the difference between 74hc32 and 74ls32?

74HC32 is a COMS device

74LS32 is a TTL device

They have different current levels, different speeds, and different stability performance.

  • What is the output current of 74ls32?

High level output current, IOH= -0.4ma. Low-level output current IOL=8ma.

  • What does the OR Gate do?

The OR gate is a digital logic gate that implements logical disjunction – it behaves according to the truth table to the right. A HIGH output (1) results if one or both the inputs to the gate are HIGH (1). If neither input is high, a LOW output (0) results.
