UNISONIC TECHNOLOGIES CO., LTD U74HC32 CMOS IC QUADRUPLE 2-INPUT POSITIVE-OR GATES DESCRIPTION DIP-14 The UTC U74HC32 devices contain four independent 2-input OR gates. They perform the Boolean function Y = A • B or Y = A+B in positive logic. SOP-14 FEATURES * Wide Operating Voltage Range of 1.0V ~ 7.0V * Low Power Consumption, 20µA Max ICC * ±20mA Output Drive at 5V * Low Input Current of 1µA Max TSSOP-14 *Pb-free plating product number: U74HC32L ORDERING INFORMATION Order Number Normal Lead Free Plating U74HC32-D14-T U74HC32L-D14-T U74HC32-S14-T U74HC32L-S14-T U74HC32-S14-R U74HC32L-S14-R U74HC32-P14-T U74HC32L-P14-T Package Packing DIP-14 SOP-14 SOP-14 TSSOP-14 Tube Tube Tape Reel Tube U74HC32L-D14-R (1)Packing Type (2)Package Type (3)Lead Plating www.unisonic.com.tw Copyright © 2005 Unisonic Technologies Co., Ltd (1) R: Tape Reel, T: Tube (2) D14: DIP-14, S14: SOP-14, P14: TSSOP-14 (3) L: Lead Free Plating, Blank: Pb/Sn 1 of 5 QW-R502-075,B U74HC32 CMOS IC PIN CONFIGURATION 1A 1 14 VCC 1B 2 3 13 12 4B 1Y 2A 4 11 4Y 3B 2Y 5 6 10 9 GND 7 8 3Y 2B 4A 3A LOGIC DIAGRAM (positive logic) A B Y FUNCTION TABLE (each inverter) INPUT A H X L B X H L OUTPUT Y H H L UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-075,B U74HC32 CMOS IC ABSOLUTE MAXIMUM RATINGS (unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Supply Voltage Range VCC 1.0~7.0 V IIK (VIN＜0 or VIN＞VCC (see Note 1) ±20 mA Input Clamp Current IOK (VOUT＜0 or VOUT＞VCC(see Note 1) ±20 mA Output Clamp Current Continuous Output Current IO(VOUT = 0 ~ VCC) ±25 mA Continuous Current Through VCC or GND ±50 mA Storage Temperature TSTG -65 ~ +150 ℃ Note : 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied.
