74HC32 Quad 2 Input OR Gate
The High Speed-CMOS has the characteristics of both standard CMOS logic series and LS-TTL series.
The features of this High Speed-CMOS logic are:
High-Speed equivalent to the LS-TTL’s
Capable of driving 10LS-TTL loads
Maximum input current of ± 1 μA at 6 V power supply
Wide supply voltage range: HC series 2 to 6 V
Wide noise margin
