US5C3309
Preliminary
3:1 MUX/DEMUX BUS SWITCH
DESCRIPTION
The UTC US5C3309 is a single 1-of-3 Multiplexer/Demultiplexer.
The low on-resistor (5Ω) allows connected to be made without any
additional ground bounce noise or propagation delay when one
channel is selected. An additional 3-State output is introduced if no
channel is selected.
FEATURES
* Low on-resistor connection between input and output (5Ω typical)
* Near-Zero propagation delay
* Direct bus connection when switches are ON
* Ultra Low Quiescent Power (0.2μA typical)
- Ideally suited for notebook applications

Notes: 1. CL includes probe and jig capacitance.
2. Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by
the output control. Waveform 2 is for an output with internal conditions such that the output is high, except
when disabled by the output control.
3. All input pulses are supplied by generators having the following characteristics: PRR≤10MHz, ZO=50Ω,
TR≤2.5ns, TF≤2.5ns.
4. The outputs are measured one at a time, with one transition per measurement.
5. TPLZ and TPHZ are the same as TDIS.
6. TPZL and TPZH are the same as TEN.
7. TPLH and TPHL are the same as TPD (S).
8. All parameters and waveforms are not applicable to all devices.
