DG2303
Vishay Siliconix
High-Speed, Low rON, 1.8-V/2.5-V/3.3-V/5-V, SPST Analog Switch
(1-Bit Bus Switch)
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 negligiblepropagation delay.
The DG2303 consist of a bi-directional input/output pins Aand B. When the output enable (OE) is low, the input/outputpins are connected. When the OE is high, the switch is openand a high-impedance state exists between input/output pinsA and B.
FEATURES

•5Ω Switch Connection Between Two Ports •Minimal Propagation Delay
Through The Switch •Low ICC
•Zero Bounce In Flow-Through Mode

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 tested. The bus switch propagation delay is a function of the RC time constant contributed by theon-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 operationof the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximumrating conditions for extended periods may affect device reliability.
