DESCRIPTION
The DG2302 is a high-speed, 1-bit, low power, TTL- compatible bus switch. Using sub-micron CMOS technology, DG2302 achieves low on-resistance and negligible propagation delay. The DG2302 consist of a bi-dir ectional input/output pins A and B. When the output enable (OE ) is low, the input/output pins are connected. When the OE is high, the switch is open and a high-impedance state exists between input/output pins A and B.

Limit forward diode current to maximum current ratings. b. All leads welded or soldered to PC Board. c. Derate 3.1 mW/°C above 70 °C. Notes: a. Room = 25 °C, Full = as determined by the operating suffix. b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet. c. Typical values are for design aid only, not guaranteed nor subject to production testing. d. Guarantee by design, nor subjected to production test. e. VIN = input voltage to perform proper function. f. Guaranteed by design and not production test ed. The bus switch propagation delay is a function of the RC time constant contr ibuted by the on-resistance and the specified load capacitance with an ideal voltage source (zero output impedance) driving the switch. 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 in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
