January 1988MM54HC00/MM74HC00Quad 2-Input NAND GateGeneral DescriptionThese NAND gates utilize advanced silicon-gate CMOStechnology to achieve operating speeds similar to LS-TTLgates with the low power consumption of standard CMOSintegrated circuits. All gates have buffered outputs. All de-vices have high noise immunity and the ability to drive 10LS-TTL loads. The 54HC/74HC logic family is functionallyas well as pin-out compatible with the standard 54LS/74LSlogic family. All inputs are protected from damage due tostatic discharge by internal diode clamps to VCC andground. FeaturesY Typical propagation delay: 8 nsY Wide power supply range: 2-6VY Low quiescent current: 20 mA maximum (74HC Series) Y Low input current: 1 mA maximumY Fanout of 10 LS-TTL loads
