四路2输入与非门 QUAD 2-INPUT NAND GATE
DESCRIPTION
The 74AC00 is an advanced high-speed CMOS QUAD 2-INPUT NAND GATE fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology.
The internal circuit is composed of 3 stages in cluding buffer output, which enables high noise immunity and stable output.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
■ HIGH SPEED: tPD = 4ns TYP. at VCC = 5V
■ LOW POWER DISSIPATION:
ICC = 2µAMAX. at TA=25°C
■ HIGH NOISE IMMUNITY:
VNIH = VNIL = 28 % VCC MIN.
■ 50Ω TRANSMISSION LINE DRIVING CAPABILITY
■ SYMMETRICAL OUTPUT IMPEDANCE:
|IOH| = IOL = 24mA MIN
■ BALANCED PROPAGATION DELAYS:
tPLH = tPHL
■ OPERATING VOLTAGE RANGE:
VCC OPR = 2V to 6V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 00
■ IMPROVED LATCH-UP IMMUNITY
