C-MOS or TTL
1. External connection
(1) The connecting wiring of CO and each terminal must be as short as possible. Owing to type, value and wiring condition of
capacitor, it may oscillate. Confirm the output waveform under the actual condition before using.
(2) ON/OFF control terminal 5 is compatible with LS-TTL. It enables to be directly drive by TTL or C-MOS standard logic
(RCA4000 series). Please make sure to use this device, pulling up to the power supply with less than 7V at the resistor less than
50kin switching ON/OFF with open collector output or in not using ON/OFF function (in keeping "ON"), because input
impedance is high in ON/OFF terminals.
(3) If voltage is applied under the conditions that the device pin is connected divergently or reversely, the deterioration of
characteristics or damage may occur. Never allow improper mounting.
(4) If voltage exceeding the voltage of DC input terminal 1 is applied to the output terminal 2 , the element may be damaged.
Especially when the DC input terminal 1 is short-circuited to the GND in ordinary operating state, charges accumulated in the
output capacitor CO flow to the input side, causing damage to the element. In this case, connect the ordinary silicon diode as
shown in the figure.
2. Thermal protection design
Maximum power dissipation of devices is obtained by the following equation.
PD=IO×(VINVO)+VIN×Iq
When ambient temperature Ta and power dissipation PD (MAX.) during operation are determined, operate element within the safety
operation area specified by the derating curve. Insufficient radiation gives an unfavorable influence to the normal operation and
reliability of the device.
In the external area of the safety operation area shown by the derating curve, the overheat protection circuit may operate to shut-
down output. However please avoid keeping such condition for a long time.
3. ESD (Electrostatic Sensitivity Discharge)
Be careful not to apply electrostatic discharge to the device since this device employs a bipolar IC and may be damaged by electro
static discharge. Followings are some methods against excessive voltage caused by electro static discharge.
(1) Human body must be grounded to discharge the electro charge which is charged in the body or cloth.
(2) Anything that is in contact with the device such as workbench, inserter, or measuring instrument must be grounded.
(3) Use a soldering dip basin with a minimum leak current (isolation resistance 10Mor more) from the AC power supply line.
Also the soldering dip basin must be grounded.
