DESCRIPTION
The DG2303 is a high-speed, 1-bit, low power, TTL-compatible bus switch. Using sub-micron CMOS technology, DG2303 achieves low on-resistance and negligible propagation delay. The DG2303 consist of a bi-directional 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.

Power Supply
Power Supply Range Power Supply Current Notes: a. b. c. d. e. f. Room = 25°C, Full = as determined by the operating suffix. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet. Typical values are for design aid only, not guaranteed nor subject to production testing. Guarantee by design, nor subjected to production test. VIN = input voltage to perform proper function. Guaranteed by design and not production tested. The bus switch propagation delay is a function of the RC time constant contributed by the on-resistance and the specified load capacitance with an ideal voltage source (zero output impedance) driving the switch.
