Description
74HC series ICs are High-speed logic gates with very low power consumption that utilize advanced silicon-gate CMOS technology and 74HC32 is one of them. 74HC32 ICs contain 4 independent, 2 input OR gate. The Boolean expression can be written as Y = A+ B or Y = ( A’.B’ )’ for each OR gate.
Internal Structure of 74HC32 device,
The 74HC32 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 8-9 ns. They can drive 10 LS-TTL loads at a time. This means that the single output pin of the OR gate can drive 10 TTL-based Low-Power Schottky( 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.
