The MC74HC1G32 is a high-speed CMOS 2-input OR gate fabricated using a silicon-gate CMOS process. This internal circuit consists of multiple stages, including a buffer output that provides high noise immunity and stable output. MC74HC1G32 output drive current is 1/2 of MC74HC series.

The high-performance silicon-gate CMOS MC74HC174A has the same pin-out as the LS174. The device inputs are compatible with standard CMOS outputs; pull-up resistors are included for compatibility with LSTTL outputs. The device consists of six D-type flip-flops with common clock and reset inputs. Each flip-flop is loaded on a low-to-high transition of the clock input. Reset is asynchronous and active low.

The MM74HCT74 uses an advanced silicon-gate CMOS process and operates at speeds similar to LS-TTL parts. It has high noise immunity and low power consumption of a standard CMOS integrated circuit and can drive 10 LS-TTL loads. This flip-flop has independent data, preset, clear and clock inputs, and Q and Q# outputs. During the forward transition of the clock pulse, the logic level at the data input is transferred to the output. The preset and clear inputs are clock independent and are accomplished with a low on the appropriate input. The 74HCT logic family is functionally and pin-out compatible with the standard 74LS logic family. All inputs are protected from electrostatic discharge damage by clamping internal diodes to VCC and ground. The MM74HCT device is suitable for interfacing between TTL and NMOS components and standard CMOS devices. These parts are also plug-in replacements for LS-TTL devices and can be used to reduce power consumption in existing designs.
