Product Features:
• Near-zero propagation delay
• 5Ω switches connect inputs to outputs when enabled
• Direct bus connection when switches are ON
16-Bit BusSwitch
Product Description:
Pericom Semiconductor’s PI5C series of logic circuits are pro-
duced in the Company’s advanced 0.6 micron CMOS technology.
• Ultra-low quiescent power (0.2 µA typical)
– Ideally suited for notebook applications
• Pin compatible with 74 series16244
• Industrial operating temperature: –40°C to +85°C
• Packages available:
– 48-pin 240 mil wide thin plastic TSSOP (A)
– 48-pin 300 mil wide plastic SSOP (V)
– 48-pin 150 mil wide plastic BQSOP (B)
The PI5C16244 and PI5C162244 are 16-bit, 4-port bus switches
that are pin compatible with the 74 series 16244 16-bit driver. Four
enable signals (nBE) turn the switches on similar to the enable
signals of the 16244. The bus switch creates no additional propagation
delay or ground bounce noise.
The PI5C162244 device has a built-in 25-ohm series resistor to
reduce noise because of reflections, thus eliminating the need for an
external terminating resistor.
