Description:

Pericom Semiconductor’s PI5C16245 and PI5C162245 are 16-bit, 2-port bus switches that are pin compatible with the 74 series 16245 16-bit transceiver. Two enable signals (nBE) turn the switches on similar to the enable signals of the 16245. The bus switch creates no additional propagation delay or additional ground bounce noise.

The PI5C162245 device has a built-in 25-ohm series resistor to reduce noise due to reflections, thus eliminating the need for an external terminating resistor.

Features:

• Near-Zero propagation delay

• 5-ohm switches connect inputs to outputs

• Direct bus connection when switches are ON

• Ultra-low quiescent power (0.2 μA typical) – Ideally suited for notebook applications

• Pin compatible with 74 series16245

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

• Packages (Pb-free & Green available):

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

   – 48-pin 150-mil wide plastic BQSOP (B)

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