74AC00 QUAD2-input NAND gates

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 technology. The internal

circuit is composed of 3 stages including buffer output, which enables high noise immunity

and stable output. All inputs and outputs are equipped with protection circuits against static

discharge, giving them 2 KV ESD immunity and transient excess voltage. Figure 30 shows

the device pinout.

The main characteristics are:

●

high speed: tPD = 4 ns (Typ.) at VCC = 5 V

●

low-power dissipation: ICC = 2 mA (max) at TA = 25 °C

●

high noise immunity: VNIH = VNIL = 28 % VCC (min.)

●

50 W transmission line driving capability

●

symmetrical output impedance: |IOH| = IOL = 24 mA (min.)

●

balanced propagation delays: tPLH at tPHL

●

operating voltage range: VCC (OPR) = 2 V to 6 V

●

pin and function compatible with 74 series 00

●

improved latch-up immunity
