74126 IC Quadruple Bus Buffers with 3-State Outputs DIP-14

Description

74126 Features Quad Bus Buffers with 3-State Outputs Separate Control for each Channel High-Impedance Output State Standard TTL Switching Voltages Specifications: Product Attribute Attribute Value Product Category: Buffers & Line Drivers Logic Family: LS Number of Input Lines: 4 Input Number of Output Lines: 4 Output Polarity: Non-Inverting Package/Case: PDIP-14 High Level Output Current: – 2.6 mA Low Level Output Current: 24 mA Quiescent Current: 36 mA Supply Voltage – Min: 4.75 V Supply Voltage – Max: 5.25 V Operating Supply Current: 62 mA Minimum Operating Temperature: 0 C Maximum Operating Temperature: + 70 C Function: Buffer/Line Driver Input Signal Type: Single-Ended Logic Type: Bipolar Number of Channels: 4 Channel Operating Supply Voltage: 4.75 V to 5.25 V Output Type: 3-State Product Type: Buffers & Line Drivers Propagation Delay Time: 18 ns at 5 V Series: SN74LS126A Subcategory: Logic ICs Technology: Bipolar Note: Like every other chip in the 74 series, this IC must be connected to power before you can use it. Most 74126 ICs support a VCC voltage of 5V. One difference between the HC and LS version of the chip is that the 74HC126 supports 2V to 6V, while the 74LS126 supports only 5V. 74126 Pinout Diagram 74126 Pin Description Pin No Pin Name Description 1 1G, 1G*’ LOW/High pin of Buffer 1 2 1A Input Of Buffer 1 3 1Y Output Of Buffer 1 4 2G,2G*’ LOW/High pin of Buffer 2 5 2A Input Of Buffer 2 6 2Y Output Of Buffer 2 7 GND Ground 8 3Y Output Of Buffer 3 9 3A Input Of Buffer 3 10 3G,3G*’ LOW/High pin of Buffer 3 11 4Y Output Of Buffer 4 12 4A Input Of Buffer 4 13 4G,4G*’ LOW/High pin of Buffer 4 14 VCC Positive Supply Applications A digital buffer (or a voltage buffer) is an electronic circuit element used to isolate input from the output.
