The M74HC04 is a high-speed CMOS hex inverter manufactured using silicon gate C2MOS technology. The internal circuit is composed of 3 stages including a buffer output which enables high noise immunity and stable output. All inputs are equipped with protection circuits to guard against static discharge and transient excess voltage.

The M74HC08 is a high-speed CMOS quad dual-input and gate fabricated with silicon gate C2MOS technology. The internal circuit is composed of two stages including a buffer output which enables high noise immunity and stable output. All inputs are equipped with protection circuits to guard against static discharge and transient excess voltage.

The M74HC132 is a high-speed CMOS quad 2-input Schmitt NAND gate fabricated with silicon gate C2MOS technology. Pin configuration and function are identical to those of the M74HC00. The hysteresis characteristics (around 20 % VCC) of all inputs allow slowly changing input signals to be transformed into sharply defined jitter-free output signals. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

The M74HC14 is a high speed CMOS hex Schmitt inverter fabricated with silicon gate C2MOS technology. Pin configuration and functions are the same as those of the M74HC04 but all inputs have a 20 % VCChysteresis level. This, together with the Schmitt trigger function, allows the device to be used on line receivers with slow rise/fall input signals. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

The M74HC151 is a high-speed CMOS 8-channel multiplexer manufactured using silicon gate C2MOS technology. It provides, in one device, the ability to select one bit of data from up to eight sources. The M74HC151 can be used as a universal function generator to generate any logic function of four variables. Outputs Y and W are complementary; the selection depends on the address inputs A, B, and C. The strobe input must be taken low to enable this device. When the strobe is high, the W output is forced high and consequently the Y output goes low. All inputs are equipped with protection circuits to guard against static discharge and transient excess voltage.
