DG2302 Vishay Siliconix High-Speed, Low rON, SPST Analog Switch (1-Bit Bus Switch with Level-Shifter) DESCRIPTION FEATURES The DG2302 is a high-speed, 1-bit, low power, TTL- • SC-70 5-Lead Package compatible bus switch. Using sub-micron CMOS technology, • 5 Ω Switch Connection Between Two Ports DG2302 • Minimal Propagation Delay achieves low on-resistance and negligible propagation delay. Pb-free Available RoHS* COMPLIANT Through The Switch The DG2302 consist of a bi-directional input/output pins A • Low ICC and B. When the output enable (OE) is low, the input/output • Zero Bounce In Flow-Through Mode pins are connected. When the OE is high, the switch is open • Control Inputs Compatible with TTL Level and a high-impedance state exists between input/output pins A and B.

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 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. 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. www.vishay.com 2 Document Number: 72072 S-70852–Rev.
