PI5C16210
20-Bit, 2-Port Bus Switch
Features
Description
ÎÎNear-Zero propagation delay
The PI5C16210 is configured as 20-bit, 2-port bus switches designed with a low ON resistance (5-ohm) allowing inputs to be
connected directly to outputs. The bus switch creates no additional propagational delay or additional ground bounce noise.
The switches are turned ON by the Bus Enable (xOE) input signal.
ÎÎ5-ohm switches connect inputs to outputs
ÎÎDirect bus connection when switches are ON
ÎÎ32X384 function with flow through pinout make board
layout easier
ÎÎUltra-low quiescent power (0.5μW typical)
àà Ideally suited for notebook applications
Pin Configuration
ÎÎIndustrial operating temperature: –40°C to +85°C

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. 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.

2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V, control inputs only); A and B 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 A and B inputs generate no significant AC or DC currents as they transition. This parameter is not tested, but is
guaranteed by design.

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 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.
