This device contains six buffers, four buffers are All inputs are equipped with protection circuits controlled by an enable input (G1) and the other against static discharge and transient excess two buffers are controlled by the other enable voltage. input (G2) the outputs of each buffer group are PIN CONNECTION AND IEC LOGIC SYMBOLS July 2001 1/10M74HC368 INPUT AND OUTPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No SYMBOL NAME AND FUNCTION 1, 15 G1, G2 3 State Output Enable Input 2, 4, 6, 10, 1A to 6A Data Inputs 12, 14 3, 5, 7, 9, 11, 1Y to 6Y Data Outputs 13 8 GND Ground (0V) 16 V Positive Supply Voltage CC TRUTH TABLE INPUTS OUTPUTS G An Yn LL H LHL HX Z X: Dont Care Z: High Impedance ABSOLUTE MAXIMUM RATINGS Symbol Parameter Value Unit V Supply Voltage -0.5 to +7 V CC V DC Input Voltage -0.5 to V + 0.5 V I CC V DC Output Voltage -0.5 to V + 0.5 V O CC I DC Input Diode Current 20 mA IK I DC Output Diode Current 20 mA OK I DC Output Current 35 mA O I or I DC V or Ground Current 70 mA CC GND CC P Power Dissipation 500(*) mW D T Storage Temperature -65 to +150 C stg T Lead Temperature (10 sec) 300 C L Absolute Maximum Ratings are those values beyond which damage to the device may occur.
