The DG2301 is a high-speed, 1-bit, low power, TTL-
compatible bus switch. Using sub-micron CMOS technology,
DG2301 achieves low on-resistance and negligible
propagation delay.
The DG2301 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.

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. V
IN
= 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.
