Preliminary
QUAD 2:1 MUX/DEMUX BUS
SWITCH
DESCRIPTION
The UTC US5C3257 is a QUAD 2:1 multiplexer/demultiplexer
with low on-resistance and is pinout and function compatible with
the TTL device. Inputs can be connected to outputs with low on
resistance (5Ω) with no additional ground bounce noise or
propagation delay.
FEATURES
* 5Ω switches connect inputs to outputs
* ESD protection on pin
* Near zero propagation delay
* Ultra Low Quiescent Power (0.2µA Typical)
–Ideally suited for notebook applications
* Direct bus connection when switches are ON
* Pin compatible with U74 series logic devices

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=5.0V, TA=25°C ambient and maximum loading.
3. Per TTL driven input (VIN=3.4V, control inputs only); I and Y pins do not contribute to ICC.
4. This current applies to the control inputs only and represent the current required to switch internal
capacitance at the specified frequency. The I and Y inputs generate no significant AC or DC currents as
they transition. This parameter is not tested, but is guaranteed by design.
