PI3B162245 (25Ω)

3.3V, Hot Insertion, 16-Bit, 2-Port BusSwitch

Product Description

Product Features

PericomSemiconductor’sPI3Bseriesoflogiccircuitsareproduced

using the Company’s advanced 0.35 micron CMOS technology.

• Near-zero propagation delay

• 5Ω switches connect inputs to outputs

• Fast Switching Speed - 4ns max.

• Permits Hot Insertion

16-bit transceiver. Two enable signals (nBE) turn the switches on

similar to the enable signals of the 16245. The bus switches create

no additional propagational delay or additional ground bounce

noise.

•

Pin compatible with 74 series16245

Operating Vcc Range: 3.0V to 3.6V

• Industrial operating temperature: –40°C to +85°C

The PI3B162245 device has a built-in 25-ohm series resistor to

reduce noise resulting from reflections, thus eliminating the need

for an external terminating resistor.

• Packages available:

– 48-pin 240 mil wide thin plastic TSSOP (A)

– 48-pin 300 mil wide plastic SSOP (V)
