The device is designed to interface directly High Speed CMOS systems with TTL, NMOS and CMOS output voltage levels This together with its schmitt trigger function allows it to be used on line receivers with slow rise/fall input signals. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. DESCRIPTION The ACT14 is an advanced high-speed CMOS HEX SCHMITT INVERTER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power applications mantaining high speed operation similar to equivalent Bipolar Shottky TTL. The internal circuit is composed of 3 stages including buffer output, which enables high noise PIN CONNECTION AND IEC LOGIC SYMBOLS March 1999 1/7 74ACT14 INPUT AND OUTPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No 1, 3, 5, 9, 11, 13 2, 4, 6, 8, 10, 12 7 14 SYMBOL 1A to 6A 1Y to 6Y GND VCC NAME AND FUNCT ION Data Inputs Data Outputs Ground (0V) Positive Supply Voltage TRUTH TABLE A L H Y H L ABSOLUTE MAXIMUM RATINGS Symbol VCC VI VO IIK IOK IO Tstg TL Supply Voltage DC Input Voltage DC Output Voltage DC Input Diode Current DC Output Diode Current DC Output Current Storage Temperature Lead Temperature (10 sec) Parameter Value -0.5 to +7 -0.5 to VCC + 0.5 -0.5 to VCC + 0.5 20 20 50 300 -65 to +150 300 Unit V V V mA mA mA mA o o ICC or IGND DC VCC or Ground Current C C Absolute Maximum Ratings are those values beyond which damage to the device may occur.
