74AC14 HEX INVERTER s s s s s s s s s HIGH SPEED: tPD = 6 ns (TYP.) at VCC = 3.3V LOW POWER DISSIPATION: ICC = 4 A (MAX.) at TA = 25 oC HIGH NOISE IMMUNITY: VNIH = VNIL = 28% VCC (MIN.) 50 TRANSMISSION LINE DRIVING CAPABILITY SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 24 mA (MIN) BALANCED PROPAGATION DELAYS: tPLH tPHL OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 14 IMPROVED LATCH-UP IMMUNITY B M (Plastic Package) (Micro Package) ORDER CODES : 74AC14B 74AC14M equivalent Bipolar Shottky TTL. The internal circuit is composed of 3 stages including buffer output, which enables high noise immunity and stable output. This together with its schmitt trigger function allows it to be used on line receivers with slow rise/fall input segnals. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. DESCRIPTION The AC14 is an advanced high-speed CMOS HEX 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 PIN CONNECTION AND IEC LOGIC SYMBOLS March 1998 1/7 74AC14 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 F UNCTIO N Data Inputs Data Oututs 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.
