PI3C3125
PI3C3126
2.5V/3.3V, High Bandwidth, Hot Insertion,4-Bit,
2-Port Bus Switch with Individual Enables
Product Description
Pericom Semiconductor聮s PI3C series of logic circuits are produced
using the Company聮s advanced sub micron CMOS technology,
achieving industry leading speed grades.
Product Features
聲 Near zero propagation delay
聲 5鈩?switches connect inputs to outputs
聲 High Bandwidth (>400 MHz)
聲 Rail-to-Rail, or 2.5V or 3.3V Switching
聲 5V I/O Tolerant
聲
2.5V Supply Voltage Operation
聲 Permits Hot Insertion
聲 Packages available:
聳 14-pin 150 mil wide plastic SOIC (W)
聳 14-pin 170 mil wide plastic TSSOP(L)
聳 16-pin 150 mil wide plastic QSOP (Q)
The PI3C3125A and PI3C3126A are 2.5V or 3.3 Volt, 4-bit bus
switches designed with four individual 5鈩?bus switches with fast
indiviual enables in an industry standard 74XX125/126 pinout.
When enabled via the associated Bus Enable (BE) pin, the 聯A聰 pin
is directly connected to the 聯B聰 pin for that particular gate. The bus
switch introduces no additional propagation delay or additional
ground bounce noise.
The PI3C3125 device has active LOW enables, and the PI3C3126A
has active HIGH enables. It is very useful in switching signals that
have high bandwidth (>400 MHz).
Applications
聲 High Bandwidth Data Switching
聲 Hot Docking
