U74CBT3306
DUAL FET BUS SWITCH
DESCRIPTION
The U74CBT3306 dual FET bus switch features independent
line switches.
Each switch is disabled when the associated output-enable
( OE ) input is high.
FEATURES
* 5-Switch Connection Between Two Ports
* TTL-Compatible Input Levels
CMOS IC

Notes: 1. CL includes probe and jig capacitance.
2. All input pulses are supplied by generators having the following characteristics: PRR10MHz,
ZO=50, tr2.5ns, tf2.5 ns.
3. The outputs are measured one at a time with one transition per measurement.
4. tPLZ and tPHZ are the same as tdis.
5. tPZL and tPZH are the same as ten.
6. tPLH and tPHL are the same as tpd(s).
7. All parameters and waveforms are not applicable to all devices.
