Input Stage

Detailed Description

The input stage is a large N-Channel FET with a P-Channel

constant-current source. This circuit has a threshold of about

1.5V, relatively independent of the V+ voltage. This means

that the inputs will be directly compatible with TTL over the

entire 4.5V - 15V V+ range. Being CMOS, the inputs draw

less than 1µA of current over the entire input voltage range

of V- to V+. The quiescent current or no load supply current

of the ICL7667 is affected by the input voltage, going to

nearly zero when the inputs are at the 0 logic level and rising

to 7mA maximum when both inputs are at the 1 logic level. A

small amount of hysteresis, about 50mV to 100mV at the

input, is generated by positive feedback around the second

stage.

The ICL7667 is a dual high-power CMOS inverter whose

inputs respond to TTL levels while the outputs can swing as

high as 15V. Its high output current enables it to rapidly

charge and discharge the gate capacitance of power

MOSFETs, minimizing the switching losses in switchmode

power supplies. Since the output stage is CMOS, the output

will swing to within millivolts of both V- and V+ without any

external parts or extra power supplies as required by the

DS0026/56 family. Although most specifications are at

V+ = 15V, the propagation delays and specifications are

almost independent of V+.

In addition to power MOS drivers, the ICL7667 is well suited

for other applications such as bus, control signal, and clock

drivers on large memory of microprocessor boards, where

the load capacitance is large and low propagation delays are

required. Other potential applications include peripheral

power drivers and charge-pump voltage inverters.

Output Stage

The ICL7667 output is a high-power CMOS inverter,

swinging between V- and V+. At V+ = 15V, the output

impedance of the inverter is typically 7Ω. The high peak
