Product Features
Product Description
2-Port Bus Switch
Near-zero propagation delay
5-Ohm switch connects inputs to outputs
Direct bus connection when switch is ON
32X384 function with flow through pinout makes
board layout easier
Ultra-low quiescent power (0.2mA typical)
ideally suited for notebook applications
Industrial operating temperature: 40°C to +85°C
Pericom Semiconductors PI3C series of Bus Switch circuits are
produced using the Companys advanced submicron CMOS
technology, achieving industry leading speed.
The PI3C16210 is configured as a 20-bit, 2-port bus switch 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 switch
is turned ON by the Bus Enable (xOE) input signal.
Packages available:
48-pin 173-mil wide plastic TVSOP (K)
