7432 IC  4 input OR gate

The OR gate is a digital logic gate that implements logical disjunction – it behaves according to the truth table. A HIGH output (1) results if one or both the inputs to the gate are HIGH (1).

Description

7432 IC – Quad 2 – input OR gate

The OR gate is a digital logic gate that implements logical disjunction – it behaves according to the truth table. 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. In another sense, the function of OR effectively finds the maximum between two binary digits, just as the complementary AND function finds the minimum.

The CMT-7432 contains four independent 2-inputs OR gates, performing the Boolean function :

Y = A + B

The CMT-7432 can operate with supply voltages from 3.3 to 5V (±10%).

There are two symbols of OR gates: the American (ANSI or ‘military’) symbol and the IEC (‘European’ or ‘rectangular’) symbol, as well as the deprecated DIN symbol. For more information see Logic Gate Symbols.
