Application to Typical Oscillation Circuits ⁴
Application to H-CMOS Inverter
Recently, high-speed C-MOS (H-CMOS) have been used
more frequently for oscillation circuits allowing high
speed and energy saving control for the microprocessor.
There are two types of H-CMOS inverters: the un-
buffered 74HCU series and the 74HC series with
buffers.
The 74HCU system is optimum for the CERALOCK^®
oscillation circuit.
Fig. 4-3 shows our standard H-CMOS circuit.
Since H-CMOS has high gain, especially in the high
frequency area, greater loading capacitor (CL) and
damping resistor (Rd) should be employed to stabilize
oscillation performance. As a standard circuit, we
recommend Toshiba's TC74CU04, but any 74HCU04
inverter from other manufacturers may be used.
The oscillation frequency for H-CMOS specifications is

adjusted by the circuit in Fig. 4-3.
