UNISONIC TECHNOLOGIES CO., LTD U74HC4049 CMOS IC HEX INVERTING HIGH-TO-LOW LEVEL SHIFTER DESCRIPTION The U74HC4049 is a high speed Si-gate CMOS device which contains six independent inverters and they perform the function Y= A . On the input circuit of this device has a modified input protection structure which has no diode connected to VCC. Input voltages of up to 15-V may therefore be used. This feature enables the inverters to be used as logic level translators, which will convert high level logic to low level logic, while operating from a low voltage power supply. For example15-V logic can be converted down to 2-V logic. At the same time each part can be used as a simple inverter without level translation. FEATURES * Inputs accept voltages to 15V * Low power dissipation * Enable to be used as a logic level translator ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HC4049L-S16-R U74HC4049G-S16-R U74HC4049L-S16-T U74HC4049G-S16-T U74HC4049L-P16-R U74HC4049G-P16-R U74HC4049L-P16-T U74HC4049G-P16-T www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., Ltd Package Packing SOP-16 SOP-16 TSSOP-16 TSSOP-16 Tape Reel Tube Tape Reel Tube 1 of 6 QW-R502-890.A U74HC4049 CMOS IC PIN CONFIGURATION Note: The N.C is stand for that the pin is not connected.
