UNISONIC TECHNOLOGIES CO., LTD U74LVC14A CMOS IC HEX SCHMITT-TRIGGER INVERTERS DESCRIPTION The U74LVC14A devices contain six independent inverters with Schmitt-trigger action which perform the Boolean function Y= A in positive logic. This device has power-down protective circuit preventing destruction of the device when it is powered down. FEATURES * Operate From 1.65V to 3.6V * Inputs Accept Voltages to 5.5V * IOFF Supports Partial-Power-Down Mode * Low Power Dissipation * Max tPD of 6.4 ns at 3.3V ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74LVC14AL-P14-R U74LVC14AG-P14-R U74LVC14AL-S14-R U74LVC14AG-S14-R www.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., Ltd Package Packing TSSOP-14 SOP-14 Tape Reel Tape Reel 1 of 5 QW-R502-436.B U74LVC14A CMOS IC PIN CONFIGURATION FUNCTION TABLE (Each Inverter) INPUT(A) OUTPUT(Y) H L L H Note: H: HIGH voltage level; L: LOW voltage level.
