The PI5C16210 is configured as 20-bit, 2-port bus switches de-
signed with a low ON resistance (5-ohm) allowing inputs to be
connected directly to outputs. The bus switch creates no addi-
tional propagational delay or additional ground bounce noise.
The switches are turned ON by the Bus Enable (xOE) input signal.
Near-Zero propagation delay
5-ohm switches connect inputs to outputs
Direct bus connection when switches are ON
32X384 function with flow through pinout make board
layout easier
Ultra-low quiescent power (0.5μW typical)

2. Typical values are at V
CC
= 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.

Notes:
1. This parameter is guaranteed but not tested on Propagation Delays.
2. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load ca-
pacitance. 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.
