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
