7432 IC Quad 2-Input OR Gate DIP-14

7432 IC Quad 2-Input OR Gate DIP-14 The SN74LS32N Quad 2-Input OR Gate IC DIP-14 5V 8mA TTL Logic is a high-speed digital logic integrated circuit belonging to the 74LS (Low Power Schottky TTL) family. It contains four independent OR gates, each performing the Boolean OR operation, where the output becomes HIGH when at least one input is HIGH. What does the 74LS32 do? The 74×32 gives you four basic OR gates that can be used individually. An OR gate is a logic gate that outputs 1 (HIGH) if one of its inputs are 1 (HIGH). In the truth table below, you can see what the output will be for any given input: The truth table for the OR gate How To Use This Chip Like every other chip in the 7400 series, this IC needs to be connected to power before you can use it. Most 7400 ICs support a VCC voltage of 5V. One difference between the HC and LS versions of the chip is that the 74HC32 supports 2V to 6V, while the 74LS32 supports only 5V. Once it’s connected, you can use any of the four basic OR gates inside. The 74HC32/74LS32 IC connected to power Output Current 74HC32: Each gate output of the 74HC32 can sink or source 4 mA when powered with 5V. 74LS32: HIGH-Level Output Current: 0.4 mA LOW-Level Output Current: 8 mA Features: Quad 2-input OR gates in a single IC. Standard TTL 5V operation (4.75V–5.25V). Low power Schottky (LS) technology for reduced power consumption. High-speed switching with ~10–15ns propagation delay. Compatible with TTL logic families. 74×32 Pinout The 74×32 has 14 pins and contains four basic OR gates laid out as shown in the pinout diagram below: Pin Name Pin # Type Description 1A 1 Input Input to the first OR gate. 1B 2 Input Input to the first OR gate. 1Y 3 Output Output from the first OR gate. 2A 4 Input Input to the second OR gate. 2B 5 Input Input to the second OR gate. 2Y 6 Output Output from the second OR gate.
