(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
6.2 ESD Ratings

6.5 Electrical Characteristics—Oscillator
VCC = 5 V, TA = full operating range (unless otherwise noted) (see block diagram)| PARAMETER | TEST CONDITIONS | TA | MIN | TYP | MAX | UNIT | |

6.6 Electrical Characteristics—Output Switch
VCC = 5 V, TA = full operating range (unless otherwise noted) (see block diagram)(1)| PARAMETER | TEST CONDITIONS | TA | MIN | TYP | MAX | UNIT | |
|---|---|---|---|---|---|---|---|
| VCE(sat) | Saturation voltage – Darlington connection |
ISW = 1 A, pins 1 and 8 connected | Full range | 1 | 1.3 | V | |
| VCE(sat) | Saturation voltage – non-Darlington connection(2) |
ISW = 1 A, RPIN8 = 82 Ω to VCC, forced β ∼ 20 |
Full range | 0.45 | 0.7 | V | |
| hFE | DC current gain | ISW = 1 A, VCE = 5 V | 25°C | 50 | 75 | — | |
| IC(off) | Collector off-state current | VCE = 40 V | Full range | 0.01 | 100 | μA | |
(1) Low duty-cycle pulse testing is used to maintain junction temperature as close to ambient temperature as possible.
(2) In the non-Darlington configuration, if the output switch is driven into hard saturation at low switch currents (≤300 mA) and high driver currents (≥30 mA), it may take up to 2 μs for the switch to come out of saturation. This condition effectively shortens the off time at frequencies ≥30 kHz, becoming magnified as temperature increases. The following output drive condition is recommended in the non-Darlington configuration:
Forced β of output switch = IC,SW / (IC,driver – 7 mA) ≥ 10, where ∼7 mA is required by the 100-Ω resistor in the emitter of the driver to forward bias the Vbe of the switch.
Forced β of output switch = IC,SW / (IC,driver – 7 mA) ≥ 10, where ∼7 mA is required by the 100-Ω resistor in the emitter of the driver to forward bias the Vbe of the switch.
