10-Bit, 2-Port Bus Switch
Product Features:
• Near zero propagation delay
• 5Ω 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
• Packages available:
– 24-pin 150 mil wide plastic QSOP (Q24)
– 24-pin 300 mil wide plastic SOIC (S24)
Product Description:
Pioneer Semiconductor’s PI5C series of logic circuits are pro-
duced in the Company’s advanced 0.8 micron CMOS technology,
achieving industry leading performance.
The PI5C3861 is a 10-bit, 2-port bus switch designed with a low ON
resistance (5Ω) allowing inputs to be connected directly to outputs.
The bus switch creates no additional propagational delay or additional
ground bounce noise. The switches are turned ON by the Bus
Enable (BE) input signal.
