Description
The PI3B3253 is a 3.3V, Dual4:1 Multi-plexer/ Demultiplexer with
Hi-Z outputs that is pinout compatible with the PI74FCT253T,
74F253, and 74ALS/AS/LS 253. Inputs can be connected to outputs
with low On-Resistance (5Ω) with no additional ground bounce
noise or propagation delay.

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading.
3. Measured by the voltage drop between I and Y pin at indicated current through the switch. On-Resistance is determined by the lower of the voltages on the two
(I,Y) pins.

Notes:
1. This parameter is guaranteed but not tested on Propagation Delays.
2. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the
switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little
propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the
switch and its interaction with the load on the driven side.
Applications Information
Logic Inputs
The logic control inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a +3.3V supply, IN may be
driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail® minimizes power consumption.
Power-Supply Sequencing and Hot Plug Information
Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC and GND before applying signals to
input/output or control pins.
