74HC30 An 8 Input NAND Gate IC (7430 IC) DIP-14 Package

74HC series ICs are High-speed logic gates with very low power consumption that utilize advanced silicon-gate CMOS technology and 74HC30 is one of them. It has balanced propagation delay and transition times. 74HC30 ICs contain an 8 input NAND gate in one package. The Boolean expression can be written as Y = ( A.B.C.D.E.F.G.H )’ or Y= A’+B’+C’+D’+E’+F’+G’+H’ for each NAND gate.

Internal Structure of 74HC30 device,

The 74HC30 ICs have a wide operating range of VCC from 2 V to 6 V. Maximum current consumption is 20 uA through Icc and 1 uA per input pin. And the propagation delay is 10 ns. They can drive 10 LS-TTL loads at a time. Which means that the output pin of 8 pin NAND gate can drive 10 TTL based Low-PowerSchottky( LS ) input pins. They can provide 4 mA on outputs at 5 V VCC. They allow inputs and outputs up to VCC. Recommended operating VCC is 5 V. Load Current can reach up to 25 mA per output pin and 50 mA for overall pins in between 0 V to VCC.
