PI5C3253
Dual 4:1 Mux/DeMux Bus Switch
Features
Description
Near-Zero propagation delay
Pericom Semiconductors PI5C3253 is a Dual 4:1 Multiplexer/
5 switches connect inputs to outputs demultiplexer with three-state outputs that is pinout compatible
with the PI74FCT253T, 74F253, and 74ALS/AS/LS 253. Inputs
Direct bus connection when switches are ON
can be connected to outputs with low On-Resistance (5) with no
ESD Protection up to 2kV HBM
additional ground bounce noise or propagation delay.
Ultra Low Quiescent Power (0.2A typical)
Ideally suited for notebook applications
Pin compatible with 74 series 253 logic devices
Packaging (Pb-free & Green available):
16-pin 150-mil wide plastic QSOP (Q)
16-pin 173-mil wide plastic TSSOP (L)
16-pin 150-mil wide plastic SOIC (W)

Notes:
1. For Max. or Min. conditions, use appropriate value speci ed under Electrical Characteristics for the applicable device type.
2. Typical values are at V = 5.0V, T = 25C ambient and maximum loading.

3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. 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.
