Description:
Pericom Semiconductor’s PI5C16245 and PI5C162245 are 16-bit, 2-
port bus switches that are pin compatible with the 74 series 16245 16-
bit transceiver. Two enable signals (nBE) turn the switches on similar
to the enable signals of the 16245. The bus switch creates no
additional propagation delay or additional ground bounce noise.
The PI5C162245 device has a built-in 25-ohm series resistor to reduce
noise due to reflections, thus eliminating the need for an external
terminating resistor.

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, T
A
= 25°C 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 A and B pin at indicated current through the switch. On-Resistance is determined by the lower of the
voltages on the two (A,B) pins.
5. This parameter is determined by device characterization but is not production tested.

Notes:
1. See test circuit and wave forms.
2. This parameter is guaranteed but not tested on Propagation Delays.
3. 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 0.25 ns for 50 pF 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.
