74AC00B Datasheet PDF - ST Microelectronics

●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 = 2µA(MAX.) 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
