DS1640/DS1640C

4 of 4

NOTES:

1. All voltages are referenced to ground.

5. Each switch is capable of carrying 300 mA maximum at 200 mV forward drop.

6. Input leakage applies to the four gate inputs and the latch input only.

7. Applies to each of four gate inputs and the latch input.

Dallas Semiconductor devices are built to the highest quality standards and manufactured for long term

reliability. All DS1640 devices are made using the same quality materials and manufacturing methods.

However, consumer versions of the DS1640 are not exposed to environmental stresses that some

commercial device manufacturing flows require. Devices that are designated as consumer product have a

“C” designator in the product number. For example, the DS1640C is a consumer grade product.
