Hex unbuffered inverter

13. Application information

Some applications are:

• Linear amplifier (see Figure 13)

• Crystal oscillator design (see Figure 14)

• Astable multivibrator (see Figure 15)

Remark: All values given are typical unless otherwise specified.

Maximum Vo(p-p) =VCC  2.0 V centered at 0.5  VCC.

Gol = open loop gain

Gv = voltage gain

R1

 3k,R2  1M

ZL >10k; Gol =20(typical)

VCC = 6.0 V

Typical unity gain bandwidth product is 5 MHz.

C1 = 47 pF (typical)

C2 = 33 pF (typical)

R1 = 1 M

 to 10 M (typical

R2 optimum value depends on the frequency and

required stability against changes in VCC or average

minimum ICC. ICC is typically 5 mA at VCC = 5 V and

fi =10 MHz.
